Instructions
- Prepare Cake Pans: Preheat oven to 350F (175C). Line bottoms of three 8-inch round cake pans with parchment paper and grease and flour the sides. Set aside.
- Mix Dry Ingredients: In a large mixing bowl, whisk together all-purpose flour, granulated sugar, light brown sugar, cocoa powder, baking soda, and salt until uniform.
- Add Wet Fats: Add neutral cooking oil and melted unsalted butter to flour mixture. Stir until fully combined.
- Incorporate Eggs and Vanilla: Add eggs and vanilla extract to the batter and stir until fully combined and uniform.
- Add Buttermilk: Gradually add buttermilk while stirring until combined completely.
- Add Hot Liquid: Slowly and carefully add very hot/boiling water or hot coffee, stirring continuously. Scrape sides and bottom of the bowl with a spatula to incorporate all ingredients.
- Bake Cake Layers: Divide batter evenly among prepared pans. Bake in preheated oven for 25 minutes. Check doneness by inserting a toothpick in center—it should come out clean or with a few moist crumbs.
- Cool Cakes: Allow cakes to cool in pans for 10-15 minutes. Run a knife along edges, invert onto cooling racks, and let cool completely before decorating.
- Prepare Raspberry Filling: In a small saucepan, whisk granulated sugar and cornstarch until combined. Add raspberries, water, and lemon juice and stir to combine.
- Cook Filling: Heat over medium stove heat, stirring constantly until berries release juices and mixture bubbles (5-10 minutes). Continue cooking and stirring for about 2 more minutes until thickened and trails form when spatula is pulled through mixture.
- Cool Filling: Transfer filling to a heatproof container to cool to room temperature before using.
- Make Chocolate Raspberry Frosting: Beat softened butter on low speed with an electric mixer until smooth and creamy.
- Add Sugar, Cocoa, and Salt: Add half of powdered sugar, cocoa powder, and salt; beat on low speed until well combined. Gradually add remaining powdered sugar and continue mixing on low until fully incorporated.
- Incorporate Raspberry Filling: While mixing on low speed, add raspberry filling in spoonfuls until evenly incorporated.
- Adjust Consistency: Add 1-2 tablespoons of heavy cream gradually and stir until frosting is smooth and pipe-able. Transfer frosting to piping bag with a large open tip.
- Assemble Cake: Level cakes if needed. Place one cake layer on serving platter. Spread thin layer of frosting on top and pipe a dam around edge.
- Fill with Raspberry Filling: Spread half of remaining raspberry filling inside piped dam. Add second cake layer and repeat dam and filling.
- Final Layer and Frosting: Add last cake layer and use remaining frosting to cover sides and top evenly. For best result, apply crumb coat and refrigerate 15 minutes before final frosting layer.
- Optional Decoration: Add ganache drip over cake if desired.
- Chill Cake: Refrigerate cake for at least 30 minutes before slicing and serving to set frosting and filling.
Notes
- You should have about 1 ⅔ cups of raspberry filling before removing any for frosting.
- Store cake in an airtight container refrigerated for up to 4 days to maintain freshness.
- Using hot coffee instead of boiling water can enhance the chocolate flavor in the cake.
- Make sure all ingredients like eggs and buttermilk are at room temperature for best batter consistency.
- For a smoother frosting, sift powdered sugar and cocoa powder before mixing.
