Ingredients

  • Spinach Smash Cake Recipe:
  • 3 1/2 cups cake flour, sifted
  • 1 tablespoon + 1 teaspoon Baking Powder
  • 1/2 teaspoon Salt
  • 6 large egg whites, at room temperature
  • 1 1/2 cups whole milk, at room temperature
  • 4 cups fresh spinach
  • 1 cup (2 sticks) unsalted butter, at room temperature
  • 1 1/2 cups Sugar
  • 2 teaspoons Vanilla Extract
  • Spinach Buttercream Frosting:
  • 3/4 cup (1 1/2 sticks) unsalted butter, cut into small pieces, at room temperature
  • 6 3/4 cups powdered sugar
  • 1 cup fresh spinach
  • 1/3 cup whole milk
  • 1 1/2 teaspoons Vanilla Extract

Preparation

Spinach Smash Cake:
1. Position the rack in the middle of the oven. Preheat oven to 350F. Coat the insides of 3-6 inch cake pans with non-stick cooking spray, line bottoms with parchment paper rounds, then spray parchment.
2. Whisk together sifted flour, baking powder and salt in a medium size bowl to combine. Set aside. In a blender, combine milk, egg whites and spinach, blend until well combined and smooth. Set aside.
3. Beat butter until creamy, about 2 minutes, with an electric mixer on medium-high speed. Add sugar gradually and beat until very light and fluffy, about 3 minutes, scraping down the bowl once or twice. Beat in the vanilla.
4. Add flour mixture in three additions, alternately with the milk-spinach mixture, while beating on low speed. Begin and end with flour, and beat briefly until smooth. Divide the batter evenly between the 3 cake pans and smooth the tops with a spatula.
5. Bake for 40-45 minutes, or until a toothpick inserted into layers shows a few moist crumbs when removed. The layers will be a light golden brown around the edges and top and will have come away from the sides of the pans.
6. Cool the pans on a wire rack for 8-10 minutes. Unmold, peel off the parchment, and place the layers directly on the racks to cool completely.

Spinach Buttercream Frosting
1. In a blender combine milk and spinach. Blend until well combined.
2. In a large bowl, with an electric mixer or a stand- mixer on medium-high, beat butter until creamy, about 2 minutes. Add one cup of sugar gradually, beating until light and fluffy about 3 minutes, scraping down the bowl once or twice. Add remaining sugar, milk-spinach mixture, vanilla and beat on high until silky smooth.

To assemble the cake:
1. Cut off the very top of the cake to make all three layers even.
2. Place on 6 inch cake on a platter and spread 1/3 cup of the frosting. Top with another 6 inch cake and spread 1/3 cup frosting. Top with remaining 6 inch cake and use remaining frosting to cover the cake.

Note: The Spinach Smash Cake can sit at room temperature for 24 hours, refrigerate for 3 days or cakes can be individually wrapped and frozen up to 3 months.
