Oven: Preheat the oven to 350°F (177ºC). Place a rack in the center of the oven.
Mix the dry ingredients: In a large bowl, whisk together the flour (2 1/2 cups), sugar (1 1/2 cups), baking soda (1 teaspoon), and salt (1 teaspoon) until well combined. (The cocoa powder and espresso powder are bloomed separately in the next step).
Bloom the cocoa: Stir the cocoa powder (3 tablespoons) and espresso powder (1/2 teaspoon) with 1 tablespoon hot water and mix until smooth and paste-like. Set aside.(You will add this below to the wet ingredients before adding the dry). Combine the wet ingredients: In a separate large bowl, whisk together the oil (1 1/4 cups), melted butter (1/4 cup), buttermilk (1 cup), eggs (2), jam (1 tablespoon), red food coloring (2 tablespoons), apple cider vinegar (2 teaspoons), and vanilla (1 tablespoon) until completely smooth.
Add the bloomed cocoa paste. Whisk the cocoa-espresso paste into the wet mixture until fully incorporated.
Combine dry and wet ingredients: Add the dry mixture to the wet mixture. Mix on low speed (or whisk gently by hand) just until the batter is smooth. Do not overmix.
Prep the cake pans (right before filling): Coat the sides and bottom of three 9-inch round cake pans with a flour-based baking spray (such as Baker’s Joy).Line each pan with a parchment round, pressing it flat. Lightly spray the parchment as well to ensure the layers release cleanly. Pan Management (Critical for 3 Even Layers)Bake on the CENTER rack only. Red velvet browns fast; top-third baking causes doming and dark edges.Do NOT crowd the pans. Keep 2 inches of space between pans and oven walls for proper airflow.Rotate pans only once.Turn front-to-back halfway through baking (around 10–12 minutes) IF your oven has hot spots.If using dark nonstick pans: Reduce oven temp to 335°F to prevent over-browning. Evenly divide the batter among the three prepared cake pans. Bake for 18–22 minutes, or until the centers spring back lightly when touched and a toothpick comes out with a few moist crumbs (not fully clean).Do not overbake — red velvet dries quickly! Cool the cake layers: Run a thin knife around the edges to loosen. Invert each cake onto a plate, then flip again onto a cooling rack so the rounded tops face up. Cool completely before frosting.
Make Frosting: In a medium mixing bowl, using an electric mixer beat together cream cheese (2 boxes) and butter (1 cup) until smooth. Gradually add powdered sugar (4 cups), beating on low speed, until combined. Add vanilla (1 teaspoons) and stir to combine.
Assemble the cake: Place the first layer upside-down on a cake stand. Spread a generous, even layer of cream cheese frosting on top. Repeat with the second layer.Place the third layer on top and frost the entire cake.
