How to Make Chocolate Mayonnaise Cake

This chocolate cake recipe is so simple to make! Just stir the ingredients together, pour the batter into a pan, and bake. It’s an easy and delicious dessert that comes together in just 10 minutes of prep time. Perfect for beginner bakers!

1. Mix Wet Ingredients: Preheat the oven to 350ºF. Spray a 9 x 13 x 2-inch cake pan with nonstick cooking spray and set aside. In a large bowl, whisk mayonnaise, warm coffee, eggs, and vanilla extract until combined.
2. Whisk Dry Ingredients: In a medium bowl, whisk together flour, sugar, unsweetened cocoa powder, baking soda, baking powder, and salt.
3. Combine: Add the flour mixture to the mayonnaise mixture and gently whisk together until fully combined.
4. Bake, Cool, and Frost: Fill the prepared cake pan and bake for 30-35 minutes, until the center of the cake springs back lightly when pressed on or a toothpick comes out clean. Allow the cake to cool completely before frosting it. I like to use my chocolate buttercream! You can also just dust it with powdered sugar and serve.

Chocolate Mayonnaise Cake Tips and Variations

Use these tips to take your cake from good to great! Trust me, one taste, and you’ll never want a store-bought cake again!

• Do I have to use coffee? You don’t have to use coffee in this cake, although I do recommend it. It adds the most incredible depth to the chocolate flavor. The coffee can be replaced with buttermilk or hot water.
• Can I use Miracle Whip instead? Yes, you can use Miracle Whip instead of mayonnaise.
• Don’t use Dutch process cocoa powder! For this cake, do not use Dutch process cocoa powder. It has been neutralized, so it will not react the same way with the other ingredients. Your cake may end up sinking in the middle.
• Some Suggested Toppings: I made my Chocolate buttercream frosting to top my cake. But you could use cream cheese frosting, vanilla frosting, a dusting of powdered sugar, cherry pie filling, fresh strawberries, or just dig in without any topping at all!

How to Store Leftover Cake

• Room Temperature: Store chocolate mayonnaise cake covered tightly with plastic wrap or in an airtight container at room temperature for up to 5 days.
• Refrigerator: To keep fresh for up to 7 days, place in an airtight container in the fridge. 
• To Freeze: The unfrosted cake may be baked and frozen for up to 3 months. Let the cake cool to room temperature before wrapping it tightly in 2-3 layers of plastic wrap. Let it thaw at room temperature before enjoying. I recommend frosting it while either frozen or chilled.
