Ingredients

Scale
  • 2 ½ cups (310g) gluten-free flour blend (e.g., Bob’s Red Mill 1-to-1 Baking Flour)
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cups (350g) granulated sugar
  • ½ cup (113g) unsalted butter, softened
  • ½ cup (120ml) vegetable oil
  • 3 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) buttermilk (or dairy-free milk plus 1 tablespoon lemon juice)
  • ½ cup (120g) plain Greek yogurt
  • 1 teaspoon natural red food coloring (or beet juice)
  • 1 cup fresh or frozen blueberries (thawed and drained if frozen)
  • 3 cups (360g) powdered sugar
  • ¾ cup (180ml) heavy cream
  • 8 oz (226g) cream cheese, softened
  • Fresh strawberries (optional, sliced for garnish or between layers)

Instructions

  1. Preheat oven to 350°F (175°C). Butter two 8-inch round cake pans and line bottoms with parchment paper.
  2. In a large bowl, whisk together gluten-free flour blend, baking powder, baking soda, and salt. Set aside.
  3. In a mixer bowl, beat softened butter and granulated sugar on medium speed until light and fluffy, about 3-4 minutes.
  4. Add eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  5. Alternate adding dry ingredients and buttermilk with Greek yogurt in three parts, beginning and ending with dry ingredients. Mix gently on low speed until smooth and pourable.
  6. Divide batter into three bowls: stir red food coloring into one third, fold blueberries into another third, leave the last plain.
  7. Pour red batter evenly into one cake pan and white batter into the other. Bake 20-25 minutes until a toothpick comes out clean. Cool 10 minutes on racks.
  8. Spread blueberry batter evenly on top of the white layer in the pan. Bake an additional 20 minutes.
  9. Cool all layers completely on racks for at least 2 hours before removing from pans.
  10. For frosting, beat cream cheese with powdered sugar until smooth. Slowly add heavy cream and beat until light and fluffy.
  11. Slice red layer in half horizontally to create two thinner layers. On a serving plate, place one red layer, spread frosting, add white and blueberry layered cake on top, then frost entire cake.
  12. Garnish with fresh strawberries if desired. Refrigerate 1-2 hours to set frosting before slicing.

Notes

Use parchment paper to prevent sticking. Measure gluten-free flour carefully (spooned and leveled). Avoid overmixing batter to prevent dense texture. Use room temperature ingredients for better mixing and lighter crumb. Check oven temperature with thermometer to avoid drying out cake. For dairy-free, substitute butter with coconut oil, use dairy-free cream cheese and yogurt, and plant-based milk with lemon juice for buttermilk. For vegan, replace eggs with flax eggs and use vegan butter and cream cheese alternatives.
