grapefruit buttercream

  • ½ cup fresh pink grapefruit juice, lightly simmered for 8 minutes and cooled
  • ½ cup (1 stick) unsalted butter, softened
  • 4 ½ to 5 cups sifted powdered sugar
  • zest of 1 grapefruit

butter cupcakes

  • 3 cups all purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 ½ cups superfine sugar
  • 4 large eggs, at room temperature
  • 1 ½ teaspoons vanilla extract
  • ½ teaspoon almond extract
  • 1 cup unsweetened Almond Breeze almond milk


  • grapefruit zest


  • Preheat oven to 350˚F.
  • Buttercream: Place butter into a bowl of a stand mixer or into a large mixing bowl and cream. With the motor running, add 2 cups of powdered sugar, ½ cup at a time, to the butter until fully incorporated and smooth. Stir in the grapefruit juice until fully incorporated. Add the remaining powdered sugar, ½ cup at a time until you have a good buttercream consistency. Set aside until ready to use. (if using at a later time, store in an airtight container and re-whip before using for best consistency)
  • Cupcakes: Place flour, baking powder and salt in a mixing bowl and whisk together. Set aside.
  • Place butter and sugar in the bowl of a stand mixer or in a mixing bowl and cream together. Add eggs, one at a time, scraping down the sides of the bowl after each addition. Fold in the vanilla and almond extract.
  • Add the flour mixture to the butter mixture and beat together until fully combined. Stir in almond milk until a loose batter has formed.
  • Line a muffin tin with cupcake liners and fill each liner ⅔ of the way with the batter.
  • Bake cupcakes for 22 to 25 minutes or until a toothpick comes out clean when inserted into the center of the cupcake.
  • Allow cupcakes to cool completely before frosting.
  • Finish the cupcakes with fresh grapefruit zest and serve.
