Ingredients

Scale

For the Chocolate Cake

  • 1 and 3/4 cups all-purpose flour
  • 3/4 cup cocoa powder (Dutch process preferred)
  • 1 and 1/2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup vegetable oil
  • 2 cups granulated sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup buttermilk (room temperature)
  • 1 cup very hot coffee (or boiling water)

For the Raspberry Frosting

  • 2 cups fresh raspberries
  • 1 cup unsalted butter (softened to room temperature)
  • 3 and 1/2 to 4 cups powdered sugar
  • 2 to 3 tablespoons whipping cream

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan to ensure the cake doesn’t stick and set it aside.
  2. Mix Dry Ingredients: In a large bowl, whisk together the all-purpose flour, Dutch process cocoa powder, baking powder, baking soda, and salt until well combined.
  3. Beat Wet Ingredients: In a separate large bowl, use a stand mixer or hand-held electric mixer to beat vegetable oil, sugar, eggs, and vanilla extract on medium speed until combined thoroughly.
  4. Combine Wet and Dry: Reduce mixer speed to low. Gradually beat in the buttermilk followed by the dry ingredient mixture. Stop the mixer and scrape down the bowl sides as needed for even mixing.
  5. Add Hot Coffee: With the mixer on low speed, carefully beat in the very hot coffee or boiling water. This step enhances the chocolate flavor and helps create a moist texture.
  6. Bake the Cake: Pour the batter into the prepared pan. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the cake to cool completely.
  7. Prepare Raspberry Puree: Place fresh raspberries in a blender or food processor and process until smooth. Strain the puree through a fine sieve, pressing with a spoon to extract juice while discarding seeds.
  8. Reduce Raspberry Puree: Pour the strained raspberry juice into a small saucepan and heat over medium heat, stirring frequently. Let it boil and reduce for approximately 10 minutes until thick and reduced to about 1/4 to 1/3 cup. Cool completely before using.
  9. Make Raspberry Frosting: In a large bowl, beat softened butter on medium speed until fluffy. Lower speed and gradually add 3 and 1/2 cups powdered sugar, mixing thoroughly. Add the cooled raspberry puree carefully, followed by whipping cream one tablespoon at a time, mixing well between additions. If frosting is too thin, add up to an additional 1/2 cup powdered sugar to reach desired consistency.
  10. Frost the Cake: For cleaner frosting application, place the cooled cake in the freezer for 20 minutes to firm up. Once chilled, use a flat edge knife or spatula to evenly spread the raspberry frosting over the cake surface.
  11. Serve: Slice the cake and serve. Enjoy the rich chocolate paired with fresh raspberry flavor!

Notes

  • Using Dutch process cocoa powder intensifies the chocolate flavor and enhances the cake’s color.
  • Hot coffee or boiling water enhances chocolate flavor but can be substituted with hot water if preferred.
  • Make sure the raspberry puree is fully cooled before adding to the buttercream to prevent separation of the frosting.
  • Chilling the cake before frosting minimizes crumbs from mixing into the icing, resulting in a cleaner finish.
  • Adjust the amount of powdered sugar in the frosting depending on the desired sweetness and consistency.
