Ingredients

Scale
  • 8 oz fresh strawberries (washed, hulled, chopped)
  • 1 cup granulated sugar (for puree)
  • 1/3 cup water
  • 1/2 cup (4 oz) unsalted butter, room temperature
  • 1 cup granulated sugar (for batter)
  • 2 large eggs (whites only)
  • 1 tsp vanilla extract
  • 3 cups all-purpose flour
  • 1 1/2 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • Zest of 1 lemon
  • 3/4 cup whole milk
  • 34 drops pink food coloring (optional)
  • 1 tsp strawberry extract (optional)
  • 1 cup (8 oz) unsalted butter, room temperature (for frosting)
  • 3 1/2 cups powdered sugar
  • 2 tbsp heavy cream
  • 1/4 cup strawberry puree (reserved for frosting)


Instructions

  1. Preheat oven to 350°F (175°C) and grease a 13×9-inch baking pan or line with parchment paper.
  2. In a saucepan, combine chopped strawberries, 1 cup sugar, and water. Bring to a boil, then simmer for 15 minutes, stirring occasionally.
  3. Mash the mixture into a puree and let it cool completely. Reserve 1/4 cup for frosting.
  4. In a large bowl, beat 1/2 cup butter until fluffy, then add 1 cup sugar and mix until light and creamy.
  5. Add egg whites and vanilla extract, mixing until fully incorporated.
  6. In a separate bowl, whisk flour, baking powder, baking soda, and salt.
  7. Gradually add dry ingredients to the batter, alternating with milk, mixing until just combined.
  8. Stir in cooled strawberry puree and lemon zest. Add food coloring or strawberry extract if desired.
  9. Pour batter into prepared pan and bake for 35–40 minutes or until a toothpick inserted comes out clean.
  10. Cool the cake completely before frosting.
  11. For frosting, beat 1 cup butter until smooth, then gradually add powdered sugar.
  12. Mix in reserved strawberry puree and heavy cream until light and spreadable.
  13. Spread frosting evenly over the cooled cake, slice, and serve.

Notes

  • Use ripe, fresh strawberries for the best natural flavor.
  • Frozen strawberries can be used but may require longer cooking time.
  • Do not overmix the batter to keep the cake light and fluffy.
  • Allow the cake to cool fully before frosting to prevent melting.
  • Store covered at room temperature for up to 3 days or refrigerate if topped with fresh fruit.
