Chocolate Mayonnaise Cake
The Chocolate Mayonnaise Cake is a rich, moist dessert where mayonnaise replaces the traditional eggs and oil, creating an incredibly tender crumb. With a deep chocolate flavor, this cake is easy to make and delivers a uniquely delicious experience that’s surprisingly light.
Equipment
- 2 Mixing bowls (large & medium)
- Electric mixer or whisk
- Measuring cups and spoons
- Rubber spatula
- 9×13-inch baking pan or two 9-inch round cake pans
- Cooling rack
- Offset spatula (for frosting)
- Sifter (for cocoa and powdered sugar)
Ingredients
For the Chocolate Mayonnaise Cake:
- 2 cups all-purpose flour
- 1¾ cups granulated sugar
- 1½ cups unsweetened cocoa powder
- 1 teaspoon baking soda
- 1½ cups mayonnaise
- 1½ cups water
- 1 teaspoon vanilla extract
For the Chocolate Buttercream Frosting:
- ¾ cup unsweetened cocoa powder sifted
- 2 to 5 tablespoons milk cream, or half-and-half (as needed for consistency)
- 1 cup unsalted butter softened to room temperature
- 4½ cups confectioners’ sugar sifted
- 2 teaspoons pure vanilla extract
Instructions
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C). Grease and lightly flour your baking pan(s) or line with parchment paper.
Step 2: Mix Dry Ingredients
- In a large mixing bowl, whisk together the flour, granulated sugar, unsweetened cocoa powder, and baking soda until well combined.
Step 3: Add Wet Ingredients
- Add mayonnaise, water, and vanilla extract to the dry ingredients. Beat with a mixer or whisk until smooth and evenly combined.
Step 4: Pour and Bake
- Pour the batter into the prepared pan(s). Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Step 5: Cool the Cake
- Remove the cake from the oven and allow it to cool in the pan for 10–15 minutes. Then transfer to a wire rack to cool completely before frosting.
Step 6: Make the Frosting
- In a separate bowl, beat the butter until creamy. Add the sifted cocoa powder and gradually mix in the confectioners’ sugar. Add the vanilla extract and enough milk or cream to achieve a smooth, spreadable consistency.
Step 7: Frost the Cake
- Once the cake is fully cooled, spread the chocolate buttercream evenly over the surface using an offset spatula or knife.
Step 8: Serve and Enjoy
- Slice, serve, and enjoy your rich, moist Chocolate Mayonnaise Cake!
Notes
For an extra indulgence, I like to top this cake with a rich chocolate frosting or a simple dusting of powdered sugar.
If you want to add a bit of crunch, chopped nuts or chocolate chips can be stirred into the batter before baking. This cake also freezes well, making it a great option for preparing in advance.
