Ingredients

Scale
  • 1 box yellow cake mix (about 15.25 oz / 433 g)
  • 1 cup sour cream (240 ml)
  • 1/2 cup vegetable oil (120 ml)
  • 3 large eggs, room temperature
  • 1 tsp vanilla extract (5 ml)
  • 8 oz cream cheese, softened (225 g)
  • 1/2 cup unsalted butter, softened (115 g)
  • 3–4 cups powdered sugar (360–480 g), sifted
  • 1 tsp vanilla extract (5 ml)
  • 2–3 tbsp milk (30–45 ml), if needed
  • 1 cup fresh blueberries (150 g)
  • 1 1/2 cups fresh strawberries, hulled and sliced (225 g)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×13 inch (23×33 cm) pan and optionally line it with parchment paper.
  2. In a large bowl, combine the yellow cake mix, sour cream, vegetable oil, eggs, and vanilla extract. Mix on medium speed for 2 minutes until smooth and well blended.
  3. Pour the batter into the prepared pan and smooth the surface with a spatula.
  4. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Start checking at 28 minutes.
  5. Cool the cake completely on a wire rack, about 1 hour.
  6. In a medium bowl, beat cream cheese and butter until smooth and creamy, about 2-3 minutes.
  7. Gradually add powdered sugar, mixing on low speed until combined. Add vanilla extract and milk if needed to reach spreadable consistency.
  8. Frost the cooled cake evenly using an offset spatula or butter knife.
  9. Arrange blueberries in the top left corner in a square shape (about one-third of the cake’s width and height). Arrange sliced strawberries in rows for the red stripes across the rest of the cake.
  10. Chill the cake for at least 30 minutes before serving.

Notes

Bring eggs and sour cream to room temperature before mixing for best results. Use fresh, firm berries and pat dry to avoid soggy frosting. Chill cake before frosting to prevent melting. The cake can be made a day ahead and refrigerated. For gluten-free or vegan versions, use appropriate substitutions. Frozen berries can be used if thawed and drained well.
