Step 1

Preheat the oven to 325°F. Line three 8-inch cake pans with parchment rounds and spray parchment and sides of pans generously with nonstick cooking spray.

Step 2

In a glass measuring cup, whisk the hot coffee and cocoa powder. Cover and let stand for 5 minutes.

Step 3

In a medium mixing bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon.

Step 4

In a large mixing bowl, whisk together the sugar, vegetable oil, and melted butter. Add in the eggs and yolk and whisk for twenty seconds, or until very well combined. Add in the buttermilk, vanilla and food coloring and whisk to combine. Whisk in the vinegar and coffee mixture. Using a fine mesh sieve, sift the flour mixture into the batter in three additions, whisking until each addition is incorporated.

Step 5

Divide the batter equally between the prepared pans. Tap the bottoms of the pans against the counter several times to release any air bubbles.

Step 6

Bake for 25 to 30 minutes, or until a cake tester or toothpick comes out clean. It’s normal for the cake to look slightly spongy on top. Place the cake pans on cooling racks. When the pans are cool enough to touch, run a thin knife around the edges of the pans to loosen the cakes. Invert onto the wire racks. Let cool completely.

Step 7

In the bowl of a stand mixer fitted with the paddle attachment, beat the cream cheese and butter on medium-high speed until very light, creamy, and smooth. Scrape down the bottom and sides of the bowl to ensure no clumps remain. Add in the vanilla and beat until combined. On low speed, gradually add in the sugar and beat until fluffy, about 3 minutes. If the frosting is too thick, add a splash of milk or cream. If it’s too thin, add more sifted powdered sugar.

Step 8

Lay one cake layer flat-side up on a cake plate or pedestal. Tuck in strips of baking paper under the cake edges to keep the plate clean.

Step 9

Use about a third of the frosting to fill the bottom cake layer, then top with the second cake layer and repeat. Place the final cake layer flat-side up. Use the rest of the frosting to ice the whole cake. Serve.

Step 10

The cake can be covered and stored in the refrigerator for up to 3 days.
