- 60 g unsweetened cocoa powder (3/4 cup; provides rich chocolate flavor)
- 250 g granulated sugar (1 1/4 cups; sweetness)
- 2 teaspoons baking powder (For leavening)
- 1 teaspoon baking soda (For leavening)
- 1/4 teaspoon kosher salt (For flavor balance)
- 300 ml strong black coffee (1 1/4 cups; brewed at double strength for deep chocolate flavor)
- 300 g mayonnaise (1 1/4 cups; full-fat mayonnaise recommended for richness)
- 1 teaspoon vanilla extract (For aroma and depth)
- 200 g unsalted butter (14 tablespoons; softened for easy mixing)
- 40 g cocoa powder (1/2 cup; sifted to prevent clumps)
- 420 g confectioners’ sugar (3 3/4 cups; sifted for smoothness)
- 2 tablespoons whole milk (For creaminess)
- 1 teaspoon vanilla extract (For enhanced flavor)
How to Make Moist Chocolate Mayonnaise Cake Step-by-Step
- Step 1: Preheat the oven to 350°F (175°C) and grease a 9- by 13-inch pan with nonstick spray. Dust with flour and shake off any excess.
- Step 2: Sift together the flour and cocoa powder into a large bowl. Add sugar, baking powder, baking soda, and salt, and whisk everything together.
- Step 3: In a separate bowl, whisk together coffee, mayonnaise, and vanilla extract until the mixture becomes foamy and well combined.
- Step 4: Pour the wet ingredients into the dry ingredients and whisk gently until the batter comes together, with a few small lumps remaining. Be careful not to overmix.
- Step 5: Scrape the batter into the prepared pan and smooth the top. Bake for 35 to 38 minutes, or until a cake tester comes out clean and the cake pulls away slightly from the sides of the pan.
- Step 6: Let the cake cool in the pan on a wire rack for 1 1/2 to 2 hours, until completely cool.
- Step 7: Beat the softened butter on medium-high speed for about 30 seconds until creamy.
- Step 8: Add sifted confectioners’ sugar and cocoa powder, followed by milk and vanilla. Mix on low speed to incorporate, then increase speed and beat for 3 minutes until smooth and fluffy.
- Step 9: Once the cake has cooled, spread the frosting evenly over the top using a spatula.
- Step 10: Slice and serve.
