The icing on this coffee-infused Mocha Cake starts out light and becomes deepest in color and flavor at the bottom. The meringue drops, tinted with cocoa and coffee extract, are dipped in chocolate, then set on the tiers. Extras can be served alongside the cake or distributed as wedding favors.
For the Assembly
- Vegetable-oil cooking spray
- 2 cups unsweetened Dutch-process cocoa powder

Preheat oven to at 350 degrees. Coat cake pans with cooking spray; cover bottoms with parchment, and coat again. Set aside. Whisk cocoa powder into coffee in a large bowl until cocoa has dissolved; set aside.
Sift together flour, baking soda, and baking powder in a large bowl; set aside.
Put butter and sugar into the bowl of an electric mixer fitted with the paddle attachment; mix on medium-high speed until pale and fluffy. Add eggs, 1 at a time, mixing well after each addition. Mix in half of the flour mixture. Mix in coffee mixture. Mix in remaining flour mixture. Divide batter among prepared pans.
Bake until a cake tester inserted into centers comes out clean. Transfer to wire racks; let cool in pans slightly. Invert cakes onto racks. Remove parchment; reinvert. Cakes can be wrapped in plastic and stored at room temperature up to 1 day.
