How to Make the Mocha Cake with Fudge Filling and Espresso Frosting
Step 1: Make the Cake Batter
Whisk together the dry ingredients (flour, cocoa powder, baking powder, baking soda, and salt). In another bowl, cream the butter, sugar, and brown sugar until fluffy, then beat in the eggs one at a time. Stir in the oil, espresso, and vanilla. Gently fold in the dry ingredients until smooth.
Step 2: Bake the Cake Layers
Divide the batter between greased and lined cake pans. Bake until a toothpick comes out clean, then let them cool completely before filling.
Step 3: Prepare the Fudge Filling
Heat the cream until just simmering, then pour over chopped dark chocolate. Let it sit a minute, then whisk until smooth and glossy. Chill until spreadable.
Step 4: Whip the Espresso Frosting
Beat softened butter until creamy, then add powdered sugar, espresso powder dissolved in a splash of cream, and vanilla. Whip until light and fluffy.
Step 5: Assemble the Cake
Spread the fudge filling between the cooled cake layers. Frost the outside with espresso frosting, smoothing or swirling as you like.
Step 6: Chill and Serve
Refrigerate for 20–30 minutes to set the layers. Slice and enjoy your dreamy mocha creation.

FAQs
Can I use instant coffee instead of espresso?
Yes! Just dissolve instant coffee granules in hot water. For stronger flavor, use espresso powder if available.
Can I make this cake ahead of time?
Absolutely. Bake the cake layers and make the fudge filling a day in advance. Assemble and frost the next day.
Can I use milk chocolate instead of dark chocolate in the fudge filling?
Yes, but keep in mind it will be sweeter and less rich. If using milk chocolate, reduce the sugar slightly in the frosting.
How do I get that smooth bakery-style frosting finish?
Use an offset spatula and a cake scraper. Chill the cake briefly, then apply a second coat of frosting to cover any crumbs.
