Ingredients
Chocolate Cake
- 1 cup (120g) all purpose flour
- ⅓ cup (33g) Dutch Process Cocoa powder
- ½ cup (100g) granulated sugar
- ½ cup (100g) brown sugar
- 1 tsp espresso powder (or instant espresso powder)
- 1 tsp baking soda
- ½ tsp baking powder
- ½ tsp salt
- 1 large egg (room temperature)
- ½ tsp vanilla extract
- ¼ cup neutral oil (vegetable, canola, or light olive oil)
- ½ cup Buttermilk (room temperature)
- ½ cup hot coffee
Blueberry Jam
- 1 cup frozen blueberries (or fresh)
- 1 tbsp granulated sugar
- 1 tsp cornstarch
- ¾ tsp lemon juice
- Zest of one lemon
Blueberry Cream Cheese Frosting
- 6 oz. cream cheese, cold (block, full fat)
- 4 tbsp unsalted butter (room temperature)
- ¼ tsp salt
- 1½ cups powdered sugar
- ¼ cup blueberry jam
Instructions
- Preheat Oven: Preheat the oven to 350°F (175°C). Grease an 8-inch round cake pan and line it with parchment paper to ensure easy removal after baking.
- Prepare Dry Ingredients: In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, espresso powder, granulated sugar, and brown sugar until evenly combined.
- Combine Wet Ingredients: In a separate bowl, beat the egg, vanilla extract, and neutral oil together. Add the buttermilk and mix until the mixture is smooth and fully combined.
- Mix Dry and Wet Ingredients: Slowly add the dry ingredients to the wet mixture and whisk until just combined. The batter will be thick.
- Add Hot Coffee: Gradually pour in the hot coffee while stirring gently until the batter becomes smooth and well combined.
- Bake Cake: Pour the batter into the prepared cake pan and bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Cool Cake: Remove the cake from the oven and let it cool completely before frosting to ensure the frosting doesn’t melt.
- Make Blueberry Jam: In a medium saucepan over medium heat, combine the blueberries, granulated sugar, cornstarch, lemon juice, and lemon zest. Cook, stirring frequently, for 4-5 minutes until the blueberries soften and the mixture thickens.
- Mash Blueberries: Remove the pan from heat and mash the blueberries while still warm using a meat mallet, potato masher, fork, or spoon, leaving some texture.
- Finish Blueberry Jam: Return the mashed blueberry mixture to the heat for an additional 30 seconds while stirring, then transfer to a heatproof bowl and let it cool to room temperature.
- Prepare Blueberry Cream Cheese Frosting: In a medium bowl, beat together the cold cream cheese, butter, and salt for about 3 minutes until smooth and creamy. Gradually add the powdered sugar (½ cup at a time), beating until fully incorporated and smooth after each addition.
- Add Blueberry Jam to Frosting: Fold in the cooled blueberry jam and beat until the frosting is uniform and fluffy. Refrigerate the frosting for 15-20 minutes before using.
- Assemble Cake: Place the cooled cake on a serving platter. Spread the cream cheese frosting evenly over the cake. Dollop a few tablespoons of blueberry jam onto the frosting and swirl it using a butter knife to create a marbled effect.
- Garnish and Serve: Top the cake with fresh blueberries for an extra burst of flavor and visual appeal. Serve and enjoy.
- Storage: Store any leftovers covered in the refrigerator for 3-5 days. Before serving leftover cake, let it sit at room temperature for 20-30 minutes to soften the frosting.
Notes
- You can use fresh blueberries instead of frozen for the jam if preferred.
- Make sure all refrigerated ingredients (egg, buttermilk, cream cheese) are at room temperature to ensure smooth batter and frosting.
- Espresso powder enhances the chocolate flavor but can be omitted if desired.
- Allow the cake to cool completely before frosting to prevent melting the cream cheese frosting.
- For best results, use Dutch Process cocoa powder for a rich chocolate taste.
