Ingredients

  • For the cake:
    • 2 ½ cups all-purpose flour
    • 1 tsp baking powder
    • ½ tsp baking soda
    • ½ tsp salt
    • 1 cup granulated sugar
    • ½ cup unsalted butter, softened
    • 2 large eggs
    • 1 tsp vanilla extract
    • 1 cup fresh strawberry puree (or mashed strawberries)
    • ½ cup buttermilk (or milk with 1 tsp lemon juice)
    • Optional: a few drops of red or pink food coloring
  • For the strawberry frosting:
    • ¾ cup unsalted butter, softened
    • 3 cups powdered sugar
    • ¼ cup strawberry puree or 2 tbsp freeze-dried strawberry powder
    • 1 tsp vanilla extract
    • Pinch of salt
    • 12 tbsp milk or cream (as needed for consistency)

Instructions

  1. Preheat oven: Heat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan.
  2. Prepare strawberry puree: Blend or mash strawberries until smooth. For stronger flavor, simmer for 10–15 minutes to reduce, then cool.
  3. Mix dry ingredients: Whisk together flour, baking powder, baking soda, and salt in a bowl.
  4. Cream butter and sugar: Beat butter and sugar until light and fluffy. Add eggs one at a time, then vanilla extract.
  5. Combine: Alternate adding dry ingredients and buttermilk, beginning and ending with the dry mix. Stir in strawberry puree (and food coloring if using) until just combined.
  6. Bake: Pour batter into the prepared pan and bake for 30–35 minutes or until a toothpick comes out clean.
  7. Cool completely before frosting.
  8. Make frosting: Beat butter until creamy, then gradually mix in powdered sugar. Add strawberry puree, vanilla, and salt. Adjust consistency with milk or cream.
  9. Frost and serve: Spread frosting evenly over cooled cake, slice, and enjoy.

Notes

  • Reduce strawberry puree for a more concentrated flavor and vibrant color.
  • Use freeze-dried strawberry powder for intense berry flavor without extra liquid.
  • Chill frosting slightly if it becomes too soft to spread.
  • This recipe works great as cupcakes—bake 18–20 minutes at 350°F.
  • For extra freshness, top with sliced strawberries before serving.
