CAKE

Preheat oven to 350°F.

Grease and flour a 9×13 inch baking dish.

In a medium bowl, sift together flour, sugar, cocoa powder, baking soda and salt. Set aside.

In a large bowl, use an electric mixture to mix together mayonnaise, vanilla, water and coffee until combined.

Slowly add in the dry ingredients until just combined.

Pour batter into prepared cake pan and bake for 30 minutes until a toothpick inserted into the center comes out clean.

Allow to cool completely.

FROSTING

In a large bowl using an electric mixer, mix together butter, cocoa and vanilla until smooth.

Alternately add in confectioner's sugar and milk until frosting reaches a spreadable consistency. You may need to add a little more sugar and/or milk to reach the desired consistency.

Tips & Tricks (5)

Room Temperature Mayonnaise Magic 🧈
Allow your mayonnaise to reach room temperature before mixing into the batter to ensure even emulsification and prevent lumps that can create dense pockets in the cake.
Brew Coffee Strong for Deep Flavor ☕
Use freshly brewed, strongly concentrated coffee (double strength) to amplify the chocolate notes and create the rich, complex cocoa flavor that makes this cake special.
Don't Overmix the Wet Ingredients 🥄
Mix the mayonnaise-based wet ingredients just until combined to prevent overdeveloping gluten, which would result in a tough, dense crumb instead of the signature soft texture.
Sift Cocoa Powder Twice 🎯
Double-sift your unsweetened cocoa powder before adding to eliminate lumps and ensure even chocolate distribution throughout the batter for consistent flavor in every bite.
Test Doneness with the Toothpick Method 🍰
Insert a toothpick in the center—it should emerge with just a few moist crumbs, not wet batter, as this cake continues to set slightly as it cools for optimal moistness.
