Ingredients You’ll Need to Make Vegan Chocolate Peanut Butter Cake

This recipe uses simple, wholesome ingredients you may already have on hand. You’ll need to gather the following:

For the cake

• 1½ cups all-purpose flour
• 1 cup organic cane sugar or coconut sugar
• ½ cup unsweetened cocoa powder
• 1 tsp baking soda
• ½ tsp salt
• 1 cup unsweetened plant milk (such as almond or oat)
• ½ cup neutral oil (like avocado or sunflower)
• 1 tbsp apple cider vinegar
• 1 tsp vanilla extract
• ½ cup hot water or freshly brewed coffee (for a deeper chocolate flavor)

For the peanut butter frosting

• ½ cup creamy peanut butter
• ¼ cup vegan butter, softened
• 1½ to 2 cups powdered sugar (adjust to preferred consistency)
• 2 to 3 tbsp plant milk

• Pinch of salt

How to Make Vegan Chocolate Peanut Butter Cake

This cake is simple to prepare and doesn’t require any fancy tools. Here’s how to bring it all together.

1. Preheat the oven
   Set your oven to 350°F (175°C). Grease and line an 8-inch round or square baking pan with parchment paper.
   
2. Mix dry ingredients
   In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, and salt until well combined.
   
3. Add the wet ingredients
   Pour in the plant milk, oil, vinegar, and vanilla. Mix gently until just combined. Then slowly stir in the hot water or coffee. The batter will be thin. This is what helps create a moist, tender texture.
   
4. Bake
   Pour the batter into the prepared pan and bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Let cool in the pan for 10 to 15 minutes before transferring to a wire rack to cool completely.
   
5. Make the frosting
   In a mixing bowl, beat the peanut butter and vegan butter together until smooth. Gradually add powdered sugar, vanilla, salt, and plant milk. Continue to beat until light and fluffy, adding more milk as needed for a spreadable consistency.
   
6. Assemble and frost
   Once the cake is completely cool, spread the frosting over the top. For extra flair, top with chopped peanuts, chocolate shavings, or a drizzle of melted dark chocolate.

Fun Ways to Customize Your Vegan Chocolate Peanut Butter Cake

You can adapt this recipe easily to match your preferences or what’s in your kitchen. Here are a few ideas to get you started:

• Add chopped peanuts or chocolate chips to the batter for texture
• Use a chocolate ganache instead of peanut butter frosting
• Turn into cupcakes by baking for 18 to 20 minutes in a lined muffin tin
• Try swirling peanut butter into the batter before baking for a marbled effect
• Add a pinch of cinnamon or espresso powder to the batter for extra depth

How to Store Vegan Chocolate Peanut Butter Cake

This cake keeps beautifully at room temperature in an airtight container for up to 3 days. 

If your kitchen is warm or the frosting is very soft, store it in the refrigerator for up to 5 days. Let it come to room temperature before serving for the best texture and flavor. 

If you prefer, you can also freeze unfrosted cake layers for up to a month. You’ll simply need to thaw and frost them when ready.
