Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
  2. Step 2: In a large bowl, whisk 2 cups all-purpose flour, 1 1/2 cups granulated sugar, 2 tsp baking powder, and 1/2 tsp kosher salt.
  3. Step 3: Add 3 large eggs, 1/2 cup melted unsalted butter, and 1 tsp vanilla extract. Beat with an electric mixer for 2 minutes until smooth.
  4. Step 4: Divide the batter equally into two bowls. Stir 1/2 cup cocoa powder into one bowl until fully incorporated.
  5. Step 5: Spoon the vanilla batter into the prepared pan, then carefully layer the chocolate batter on top. Use a knife to create a swirling pattern.
  6. Step 6: Bake for 30-35 minutes until a toothpick inserted in the center comes out clean. Cool completely in the pan.
  7. Step 7: For frosting, whisk 1 cup powdered sugar and 1/4 cup heavy cream until smooth. Spread evenly over the cooled cake. Store at room temperature for up to 3 days.
