Step-by-Step Instructions for Espresso Martini Cake
Step 1: Preheat the Oven and Prep Pans
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch or 9-inch round cake pans, or line with parchment paper.
Step 2: Combine Dry Ingredients
In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
Step 3: Mix the Wet Ingredients
In another bowl, beat the eggs, granulated sugar, and brown sugar until light and fluffy. Then add the oil, milk, brewed espresso, vodka, coffee liqueur, and vanilla extract. Mix until well combined.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients into the wet ingredients. Stir until the batter is smooth and lump-free. Do not overmix.
Step 5: Bake the Cake
Divide the batter evenly between the prepared pans. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Step 6: Make the Espresso Buttercream
In a mixing bowl, beat softened butter until light and fluffy (2–3 minutes). Gradually add powdered sugar, 1 cup at a time, beating between additions.
Add brewed espresso, coffee liqueur, vanilla, and salt. Beat until creamy and smooth. Adjust the consistency with more powdered sugar or a splash of espresso as needed.
Step 7: Assemble and Frost
Once the cakes are completely cool, place one layer on a serving plate. Spread a generous amount of frosting on top. Place the second layer and frost the top and sides evenly.
Step 8: Decorate and Serve
Top with chocolate-covered espresso beans, a light dusting of espresso powder, or chocolate shavings. Chill for 15–20 minutes to firm up before slicing.
