Step 1

Preheat oven to 350°F. Grease and line two 8-inch cake pans with parchment paper.

Step 2

In a large bowl, whisk together sugar, cocoa powder, flour, baking soda, baking powder, and salt. In a separate bowl, whisk oil, vanilla, flax eggs, and milk.

Step 3

Pour the wet ingredients into the dry, whisking until no lumps remain. Pour in brewed coffee, mixing until just combined.

Step 4

Pour batter into prepared pans and bake for roughly 30 minutes, or until a knife inserted in the center of the cake comes out clean. Cool completely on a wire rack before frosting.

Step 5

To make the frosting, place all the ingredients in a stand mixer. Cream on low speed, gradually increasing to high speed for 1 minute, until mixture has lightened slightly and is fluffy.

Step 6

Frost cake by placing first cake layer onto a cake stand. Top with a healthy dose of frosting. Spread evenly, then repeat with second layer. Use remaining frosting to frost sides of the cake. Last, use the back of a spoon to create a large swirling pattern all around the cake!
