Decorations: Fresh strawberries, sprinkles, crushed chocolate, and small candies are all suggested toppings to finish the cake.

How to Make This Chocolate Strawberry Cake

- Prepare pans: Preheat oven to 325°F. Grease and flour two 8-inch round cake pans, or use a baking spray with flour.
- Mix batter: Combine the wet ingredients (oil, vanilla, sour cream, heavy cream, and eggs) then add the boxed cake mix along with cocoa and optional espresso powder. Mix until just combined.
- Bake: Divide batter evenly between prepared pans and bake 25–30 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely before frosting.

How to Make Strawberry Buttercream

- Cook strawberries: In a medium saucepan combine ½ cup chopped strawberries, ¼ cup water, and a pinch of salt. Heat over medium and mash as the mixture simmers until reduced to about ¼ cup (roughly 3–4 minutes). Cool completely.
- Make basic buttercream: Beat 1½ cups softened butter until fluffy. Add 1½ teaspoons vanilla, 6½ cups powdered sugar, and about 5 tablespoons heavy cream. Beat to form a smooth buttercream.
- Finish buttercream: Stir in the cooled strawberry reduction, 3–4 drops strawberry oil if using, and a few drops of neon pink gel coloring to reach the desired color. Adjust texture with additional powdered sugar (if too thin) or extra cream (if too stiff).

How to Decorate the Cake

- Layer: Place the first cake layer on your board. Put a generous layer of strawberry buttercream on top, then set the second layer in place. Fill any gaps with more buttercream and chill the cake briefly to set the filling.
- Frost: Frost the cake with the remaining buttercream. For a very smooth, professional finish, do a thin crumb coat, chill, then apply a final coat (this may require doubling the frosting).
- Ganache: Warm ¼ cup heavy cream with 1 cup semi-sweet chocolate chips in a microwave-safe bowl, stirring every 30 seconds until smooth. Pour ganache over the chilled frosted cake and let it drip down the sides.
- Decorate: Add fresh strawberries, crushed chocolate, sprinkles, and candies before the ganache sets for the best appearance.



Expert Tips
Level the cakes: If the tops domed while baking, trim them with a serrated knife so the layers sit flat.
For a smooth finish: Double the frosting and apply a crumb coat, chill, then finish with a final layer for sharp edges.
Strawberry flavor: Start with 2 drops of concentrated strawberry oil and add more to taste; a little goes a long way.
Extra filling: Add strawberry jam or thinly sliced strawberries between layers for more fruit flavor.
