strawberry frosting

  • ¼ heaping cup freeze-dried strawberries
  • 2 cups powdered sugar
  • 1 cup (2 sticks) unsalted butter, softened
  • 2 to 3 tablespoons whole milk
  • pinch of salt


  • roughly crushed freeze-dried strawberries
  • white chocolate crispy balls optional


  • Preheat oven to 350˚F.
  • Lightly grease a 9”x 13” baking pan and line with parchment (so longer sides of pan have a couple inches of overhang on each side).
  • In a large bowl whisk together flour, baking powder and salt. Set aside.
  • In the bowl of a stand mixer, cream together butter and sugar , with the paddle attachment, until light and fluffy.
  • Scrape down sides of bowl and with motor running add eggs, one at a time, until incorporated. Stir in vanilla.
  • Add ⅓ of the flour mixture and ⅓ of milk to the butter mixture and mix. Continue adding flour and milk in thirds until fully incorporated and batter is smooth, making sure not to over mix.
  • Pour batter into prepared baking dish and bake for 30 to 35 minutes or until golden brown on top and a toothpick come out clean when inserted into the center of the cake.
  • Place cake onto a cooling rack and cool completely. Once cooled, lift cake out by the parchment paper. Peel parchment paper from cake and transfer cake to a platter or cutting board.
  • For frosting: Place freeze-dried strawberries and powdered sugar into a food processor and pulse until smooth.
  • Cream butter in a mixing bowl of a stand mixer until light and fluffy. Add powdered sugar mixture to butter, with motor running until fully incorporated. Scrape down sides of bowl, add milk and beat together until smooth.
  • To assemble: Scoop frosting onto top of cake and spread evenly over the top with a spatula. Sprinkle with crushed freeze-dried strawberries and white chocolate crispy balls, if using. Slice and serve.
