Heat heavy cream in a small saucepan until it’s steaming—don’t let it boil.
1/2 cups heavy cream
Pour the hot cream over white chocolate in a heatproof bowl and let it sit for 2–3 minutes.
1 1/2 cups white chocolate (13.5oz)
Gently stir until smooth and glossy. If needed, microwave in 5-second bursts to melt any remaining bits.
Cover with plastic wrap and chill for 2–3 hours, until thick but still scoopable.
Once chilled, whip the ganache using a stand mixer with the whisk attachment until light, fluffy, and soft peaks form—don’t overwhip.

Preheat oven to 350°F. Line the bottom of three 8-inch pans with parchment paper, then grease and dust the sides.
In a medium bowl, sift together flour mixture—flour, cocoa powder, baking soda, baking powder, and salt.
2 1/4 cups all-purpose flour, 1 cup Dutch-processed cocoa powder, 2 teaspoon baking powder, 1 teaspoon baking soda, 1 teaspoon salt
In the bowl of a stand mixer with the paddle attachment, mix oil and sugar on medium speed for 1 minute.
1 1/4 cups vegetable oil, 1 3/4 cups granulated sugar
Add eggs one at a time, then vanilla and sour cream. Mix just until combined.
4 large eggs, 1 tsp pure vanilla extract, 2/3 cup sour cream
Alternate adding dry ingredients and hot coffee to the wet mixture, starting and ending with dry. Mix on low speed, scraping the bowl as needed.
1 cup strong coffee
Pour the chocolate cake batter evenly into the pans.
Bake for 23–28 minutes, or until a toothpick inserted in the center comes out clean.
Let cool in pans for 10 minutes before moving to a cooling rack.

In a large bowl, beat butter until fluffy—about 1 minute.
1 cup unsalted butter
Add cocoa powder and powdered sugar slowly, mixing on low speed to avoid a sugar cloud.
2/3 cup cocoa powder, 3 1/2 cups powdered sugar
Add vanilla, salt, and heavy cream. Beat on medium speed until smooth and fluffy.
2 teaspoon pure vanilla extract, 1/2 teaspoon salt, 2-4 Tablespoon heavy cream

Trim the top of the cake layers if needed to create a flat surface.
Spread a dab of frosting on your cake board to anchor the first layer.
Pipe a frosting border and fill with half of the whipped ganache.
Add the second layer and repeat with the rest of the ganache. Top with the final layer and press gently.
Apply a crumb coat of frosting to the entire cake. Chill for 15–20 minutes.
Frost the cake generously with the remaining frosting using an offset spatula.
Optional: Top with chocolate curls, chocolate drip, or mini chocolate chips.

Add-ons & Substitutions

Swap Dutch-process cocoa powder with natural cocoa powder if needed, but the cake will be slightly less dark and rich.
Add mini chocolate chips or semi-sweet chocolate chips to the batter for pockets of melty chocolate.
For a fun twist, sprinkle the top with chocolate curls, whipped cream, or milk chocolate shavings.

Use room temperature ingredients for a smoother, more cohesive batter and better bake times.
Don’t overmix once the wet and dry ingredients are combined—it can make the cake dense.
Press the back of a knife gently along cake edges to smooth frosting lines.
For best structure, chill each layer in the fridge before assembling the chocolate layer cake.
Always test with a toothpick; every oven runs a little differently, and this ensures perfectly moist cake layers.
