Diving Deeper into Key Ingredients for the Perfect Vegan Chocolate Sheet Cake
Understanding the role of each ingredient is key to successful vegan baking. Here’s a closer look at some essential components of this delicious sheet cake:
Apple Cider Vinegar (ACV): This is a crucial player in our egg-free cake! Since we’re not using eggs for leavening, the vinegar steps in to react with the baking soda. This acid-base reaction creates carbon dioxide bubbles, which are trapped in the batter and cause the cake to rise, resulting in a light and airy texture. While some eggless cakes might rise adequately without vinegar, for this specific recipe, its inclusion ensures consistent results and optimal lift. If you don’t have ACV on hand, white vinegar or even fresh lemon juice can be used interchangeably, as they provide the necessary acidity for the reaction.
Cocoa Powder: The type of cocoa powder you choose can subtly influence the cake’s flavor and color. You can confidently use either natural cocoa powder or Dutch-processed cocoa powder in this recipe. The main difference lies in their acidity: natural cocoa is acidic, while Dutch-processed cocoa has been treated to neutralize its acidity. Typically, this acidity difference dictates which leavening agent (baking soda or baking powder) to use. However, because our recipe includes additional acidity from the apple cider vinegar, both types of cocoa will work wonderfully. Natural cocoa will yield a slightly lighter colored cake with a sharper, more fruity chocolate flavor, while Dutch-processed cocoa will give you a darker cake with a smoother, mellow chocolate taste. Feel free to use your preferred type!
Flour: The original recipe calls for whole wheat flour, which adds a lovely nutty flavor and a bit more density to the cake, along with increased fiber. However, if you prefer a lighter, more traditional cake texture, all-purpose white flour works perfectly as a substitution. When using all-purpose flour, you might find that the baking time needs a slight adjustment, typically an additional 3-5 minutes, so keep an eye on it. For a gluten-free option, a good quality 1:1 gluten-free baking blend (one that contains xanthan gum) can be used, though results may vary slightly in texture and you might need to adjust liquid or baking time.
Oil: In vegan baking, oil plays a vital role in creating moisture and richness, mimicking the functions of butter. Extra virgin olive oil is specified here, which imparts a subtle, pleasant flavor that complements the chocolate beautifully. However, any neutral-flavored oil like canola oil, vegetable oil, or melted coconut oil (if you don’t mind a slight coconut flavor) can be used as a substitute. The key is to ensure it’s a liquid oil at room temperature for easy mixing into the batter.
Effortless Guide: How to Make a Chocolate Sheet Cake from Scratch
Creating this delicious vegan chocolate sheet cake is incredibly straightforward. Follow these simple steps for a perfect bake every time:
- Prepare the Dry Ingredients: In a generously sized mixing bowl, combine all your dry ingredients – that’s the flour, coconut sugar, cocoa powder, baking soda, and kosher salt. Give them a good whisk to ensure they are thoroughly combined and there are no clumps, especially if your cocoa powder tends to be lumpy (a quick sift can prevent this).
- Incorporate Wet Ingredients: Next, pour in the room-temperature water, extra virgin olive oil, apple cider vinegar, and vanilla extract. Using your whisk, mix gently but thoroughly until all the dry ingredients are fully incorporated into a smooth, consistent batter. Be careful not to overmix; just combine until no streaks of flour remain.
- Pan Preparation and Pouring: Prepare your 9×13 inch cake pan by greasing it lightly and lining the bottom and sides with parchment paper. This step is crucial for easy removal of the cake once baked. Pour the chocolate cake batter evenly into the prepared pan. Once poured, gently tap the bottom of the pan against your counter a few times to release any trapped air bubbles, ensuring an even bake.
- Bake to Perfection: Place the pan in your preheated oven at 350°F (175°C) and bake for approximately 25-27 minutes. The cake is done when a toothpick inserted into the center comes out clean or with a few moist crumbs attached. Avoid overbaking, as this can lead to a dry cake. Allow the cake to cool completely on a wire rack before attempting to frost it.
- Whip Up the Frosting: While the cake cools, prepare your simple peanut butter frosting. Scoop out the thick, solidified coconut cream from your refrigerated cans of coconut milk into a deep mixing bowl (you can discard the remaining coconut water or save it for a smoothie!). Beat the coconut cream on high with an electric mixer until it’s light and fluffy, about 1-2 minutes. Then, add the natural smooth peanut butter and maple syrup. Continue to beat on high for another few minutes until the frosting is wonderfully whipped and creamy. Be mindful not to overmix, as coconut cream can sometimes separate if beaten too long.
- Frost and Garnish: Once your cake is completely cool, spread the creamy peanut butter frosting generously over the top. For an extra touch of flair and texture, sprinkle with some colorful sprinkles or a handful of crushed peanuts. Slice and serve immediately, or store for later enjoyment!
Frequently Asked Questions About Vegan Chocolate Sheet Cake
A sheet cake is a single-layer rectangular cake, typically baked in a large, shallow pan (like a 9×13 inch or larger). They are usually around 2 inches high, frosted generously, and are a fantastic choice for feeding a crowd or for easy transport to parties and potlucks. Their flat, expansive surface makes frosting and decorating a breeze!
This particular chocolate sheet cake recipe is designed for a standard 9×13 inch rectangular baking pan. While other sheet cake recipes might use larger jelly roll pans or 11×17 inch rimmed baking sheets, this specific recipe has not been tested in those alternative sizes. Sticking to the 9×13 inch pan will ensure the correct cake height and baking time.
When cut into generous, rectangular portions, this 9×13 inch sheet cake typically yields about 24 pieces. However, you have the flexibility to cut it into larger, more indulgent slices for fewer people, or smaller squares if you’re serving a very large gathering.
Absolutely! To make a smaller batch, simply halve all the ingredients listed in this recipe. Bake the half-sized batter in an 8-inch square cake pan at the same temperature, 350°F (175°C). The baking time will be slightly longer, generally between 30-35 minutes, or until a toothpick inserted into the center comes out clean.
If the cake is unfrosted, it can be stored in an airtight container at room temperature for up to 2-3 days. However, if you’ve frosted it with the delicious peanut butter frosting included in this recipe (which is coconut milk-based), the cake should be stored in an airtight container in the refrigerator to maintain its freshness and texture.
When stored properly in the refrigerator (especially if frosted), this vegan chocolate sheet cake will remain fresh and delicious for 3-4 days. Ensure it’s in an airtight container to prevent it from drying out or absorbing other odors from the fridge.
You can certainly freeze the unfrosted cake to enjoy later! Once the cake has cooled completely, wrap it tightly in several layers of plastic wrap, followed by a layer of aluminum foil, and freeze for up to 3 months. I don’t recommend freezing it with the peanut butter frosting, as the texture of the frosting may change upon thawing. To defrost, simply transfer the wrapped cake to the refrigerator overnight before unwrapping and frosting.
Yes, you can! For a gluten-free version, substitute the whole wheat flour with a good quality 1:1 gluten-free all-purpose baking flour blend that contains xanthan gum. Keep in mind that gluten-free flours can sometimes absorb more liquid, so the cake’s texture might be slightly different. You may also need to adjust the baking time by a few minutes, so keep a close watch and use the toothpick test.
Absolutely! This chocolate sheet cake provides a wonderful base for a variety of frostings. While the peanut butter frosting is a fantastic pairing, feel free to get creative. A classic vegan chocolate ganache, a simple vanilla buttercream, a tangy vegan cream cheese frosting, or even a light dusting of powdered sugar would all be delicious options depending on your preference.
Several factors can contribute to a dry or sunken cake. A dry cake is often a result of overbaking, so ensure you’re using the toothpick test accurately and removing it from the oven as soon as it’s done. A sunken cake can be caused by opening the oven door too early, overmixing the batter (which develops too much gluten and can make the cake tough and prone to sinking), or using old, inactive leavening agents like baking soda. Always ensure your baking soda is fresh for optimal lift.
Pro Tips & Smart Substitutions for Your Vegan Chocolate Sheet Cake
- Achieve an Even Bake: The batter for this cake is naturally quite thick. After pouring it into your prepared pan, make sure to spread it out evenly to the edges and into the corners. Gently tap the bottom of the pan on your kitchen counter a few times. This simple trick helps to level out the batter and release any trapped air bubbles, promoting a more consistent and even bake.
- Sweetener Options: While coconut sugar adds a subtle caramel note and a slightly richer flavor, if you don’t have it, regular granulated sugar works perfectly well as a direct 1:1 substitute. The cake will still be deliciously sweet and moist.
- Flour Flexibility: As mentioned, this recipe works beautifully with both whole wheat flour and all-purpose white flour. If you opt for all-purpose flour, simply add another 3-5 minutes to the baking time and continue to check for doneness with a toothpick. For gluten-free needs, a quality 1:1 gluten-free blend can be used, but observe the batter consistency and adjust baking time as needed.
- Vinegar Alternatives: Apple cider vinegar is fantastic for its leavening properties, but if it’s not available, plain white vinegar will achieve the exact same chemical reaction with the baking soda and work just as effectively without altering the taste of the cake.
- Cocoa Powder Choice: Both natural cocoa and Dutch-processed cocoa powder perform well in this recipe. Natural cocoa is more acidic and provides a slightly sharper chocolate flavor, while Dutch-processed cocoa is less acidic and offers a smoother, darker chocolate profile. Choose based on your preference!
- Frosting Nut Butter Swaps: The peanut butter frosting is incredibly popular, but you’re not limited to just peanut butter! Feel free to use any smooth nut butter you enjoy, such as almond butter, cashew butter, or even sunflower seed butter for a nut-free alternative. Each will bring its unique flavor profile, pairing wonderfully with the rich chocolate cake.
- Perfect Coconut Whipped Cream: When preparing the coconut whipped cream frosting, it’s crucial to use full-fat coconut milk that has been thoroughly refrigerated (preferably for 24 hours) so the solids can separate and firm up. Be cautious not to overmix the coconut whipped cream, as prolonged beating can cause it to lose its fluffy texture and potentially start to separate, becoming grainy or oily. Beat just until light and creamy.
- Measure Accurately: Especially when it comes to flour, use the ‘spoon and level’ method rather than scooping directly from the bag. This prevents over-packing the flour, which can lead to a dry cake.
- Don’t Peek Too Soon: Avoid opening the oven door frequently during baking, especially in the first 15-20 minutes. Sudden temperature changes can cause the cake to sink.
- Cool Completely: Ensure the cake is entirely cool before applying frosting. A warm cake will melt your beautiful frosting!

Description
Easy Chocolate Sheet Cake is a simple vegan chocolate cake recipe that’s made without eggs, butter or milk. You need just a few basic pantry ingredients to make this rich and delicious chocolate dessert!
Ingredients
For the cake:
- 3 cups whole wheat flour
- 1 1/2 cups coconut sugar
- 1/2 cup cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon kosher salt
- 2 cups water, room temperature
- 3/4 cup extra virgin olive oil
- 2 tablespoons apple cider vinegar
- 2 teaspoons vanilla extract
For the coconut whip:
- 2 cans (400 ml) full fat coconut milk, refrigerated (see note)
- 3 tablespoons natural smooth peanut butter
- 2 teaspoons maple syrup
Optional toppings:
- Sprinkles
- Crushed peanuts
Instructions
- Pre-heat your oven to 350°F (175°C). Prepare your 9×13 inch cake pan by greasing it lightly, then lining the bottom and sides with parchment paper, leaving an overhang on two sides to easily lift the cake later.
- In a large mixing bowl, thoroughly whisk together all the dry ingredients: flour, coconut sugar, cocoa powder, baking soda, and kosher salt. If your cocoa powder is clumpy, sift it first to ensure a smooth batter.
- Add the wet ingredients to the dry mixture: water (at room temperature is best), extra virgin olive oil, apple cider vinegar, and vanilla extract. Whisk until all the dry ingredients are well combined and the batter is smooth. Be careful not to overmix, as this can lead to a tough cake.
- Pour the prepared batter evenly into your greased and parchment-lined pan. Gently tap the bottom of the pan against a hard surface a few times to release any air bubbles and help level the batter.
- Bake for 25-27 minutes, or until a wooden skewer or toothpick inserted into the middle of the cake comes out clean or with a few moist crumbs attached. Avoid overbaking.
- Remove the cake from the oven and let it cool in the pan for about 10-15 minutes. Then, using the parchment paper overhang, carefully lift the cake out of the pan and transfer it to a wire rack to cool completely. Alternatively, you can let the cake cool fully in the pan and frost it there, which can sometimes make transport easier.
- To make the frosting, open your two cans of refrigerated full-fat coconut milk. Scoop out only the thick, solidified coconut cream into a deep mixing bowl. You can discard the clear coconut water or reserve it for use in smoothies or other recipes.
- Using an electric mixer, beat the solidified coconut milk on high speed for about one minute until it begins to lighten and fluff. Scrape down the sides of the bowl, then add the natural smooth peanut butter and maple syrup. Continue to beat on high for a few more minutes until the frosting is light, airy, and creamy. Remember not to overmix, as coconut cream can sometimes separate if beaten excessively.
- Once the cake is entirely cool, spread the luscious peanut butter frosting evenly over the top. Decorate with sprinkles, crushed peanuts, or your favorite toppings for an extra festive touch.
- Serve your easy chocolate sheet cake immediately and enjoy! Store any leftovers in an airtight container in the refrigerator for 3-4 days to maintain freshness.
Notes
- For the best coconut whipped cream, the full-fat coconut milk needs to be refrigerated overnight, or ideally for 24 hours. This allows the coconut milk solids to completely separate and solidify, making them perfect for whipping.
- This versatile cake can be made using regular all-purpose white flour instead of whole wheat. If you make this substitution, simply add an additional 3-5 minutes to the baking time to ensure it cooks through.
- If you do not have apple cider vinegar on hand, white vinegar is an excellent alternative that will function identically in the recipe, providing the necessary acidity for leavening.
- Both natural cocoa powder and Dutch-processed cocoa powder work wonderfully in this recipe, yielding slightly different but equally delicious chocolate flavors.
