Ingredients

Scale
  • 1 ½ cups (180g) all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup (115g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • ½ cup (120ml) whole milk, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup (150g) fresh mixed berries, roughly chopped (blueberries, raspberries, strawberries)
  • 1 cup (240ml) heavy whipping cream, chilled
  • 2 tablespoons powdered sugar
  • ½ teaspoon pure vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, or line them with parchment paper for easy removal.
  2. In a medium bowl, sift together the flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat the softened butter and granulated sugar with an electric mixer on medium speed until light and fluffy, about 3-4 minutes.
  4. Beat in the eggs one at a time, then mix in the vanilla extract until smooth.
  5. With the mixer on low, add the dry ingredients in three parts, alternating with the milk, starting and ending with the dry ingredients. Mix just until combined.
  6. Fold in the chopped fresh mixed berries gently using a rubber spatula.
  7. Divide the batter evenly between the prepared pans and smooth the tops. Tap the pans gently on the counter to release air bubbles.
  8. Bake for 25-30 minutes until golden on top and a toothpick inserted in the center comes out clean.
  9. Cool the cakes in the pans for 10 minutes, then turn out onto a wire rack to cool completely.
  10. To make the frosting, beat the chilled heavy cream, powdered sugar, and vanilla extract on high speed until soft peaks form. Do not overbeat.
  11. Place one cake layer on a serving plate. Spread a generous layer of whipped cream frosting on top, then add the second cake layer.
  12. Frost the top and sides evenly. Garnish with extra fresh berries if desired.
  13. Chill the assembled cake in the refrigerator for about 30 minutes before serving to firm up the frosting.

Notes

Pat berries dry if very juicy to avoid soggy batter. Use chilled bowl and beaters for whipping cream to achieve fluffier frosting. Do not overmix batter or overbeat cream. Cool cake completely before frosting to prevent melting.
