How to Make It
Follow these simple steps to create your cake:
Preheat the Oven
Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking.
Mix Dry Ingredients
In a large bowl, mix together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
Combine Wet Ingredients
Add eggs, milk, oil, and vanilla to the dry ingredients. Beat on medium speed for 2 minutes until smooth.
Stir in Water
Carefully stir in the boiling water (the batter will be thin). This step is essential for moisture.
Pour the Batter
Pour the batter evenly into the prepared pans. Tap the pans gently on the counter to remove air bubbles.
Bake the Cakes
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool for 10 minutes, then remove from pans to cool completely.
Prepare the Frosting
For the frosting, beat softened butter until creamy. Gradually add powdered sugar, brewed coffee, and vanilla until smooth and fluffy.
Frost the Cake
Once the cakes are completely cool, spread the frosting between the layers and over the top and sides of the cake to finish.
How to Store It
Fridge: Store in an airtight container for up to 4 days.
Freezer: Yes, it can be frozen for up to 3 months.
Reheat: Microwave a slice for 10-15 seconds if desired.
