Shamrock Milkshake Cupcakes

McDonald’s has the Shamrock Milkshake and now, you can have a Shamrock Milkshake Cupcake. Thanks to Better Homes and Gardens, this minty cake will have you smiling with each bite. I had to tweak a few parts to make it gluten free and dairy free (which unfortunately a Shamrock Milkshake is not) But it’s ok! This is going to be delicious!

Shamrock Milkshake Cupcakes


  • 4 egg whites
  • 2 cups all-purpose gluten free flour (Better Batter or Bob’s Red Mill or whatever you prefer – add xanthan gum accordingly if using a mix that does not have xanthan gum in it already)
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup buttermilk or buttermilk substitute: (make the substitute and then only use 1 cup of it)
    • 1 1/2 cups coconut or rice milk
    • 1/2 or 2/3 cup sugar
    • 3 tablespoons vegan butter (Earth Balance)
    • 1 teaspoon pure vanilla extract
  • 1/4 cup green creme de menthe**
  • 1/2 cup vegan shortening (Earth Balance)
  • 1 3/4 cups sugar
  • 1 teaspoon pure vanilla extract
  • 1 recipe White Chocolate Frosting
  • Green food coloring
  1. Allow egg whites to stand at room temperature for 30 minutes. Meanwhile, line twenty to twenty-two 2-1/2-inch muffin cups tins with festive paper liners. In a medium bowl stir together flour, baking powder, baking soda, and salt. In a 2-cup glass measuring cup combine the buttermilk and the creme de menthe. Set aside.
  2. Preheat oven to 350ºF. In a large mixing bowl beat shortening with an electric mixer on medium to high speed for 30 seconds. Gradually add sugar, about 1/4 cup at a time, beating on medium speed until light and fluffy. Beat in vanilla. Add egg whites, one at a time, beating well after each addition. Alternately add flour mixture and buttermilk mixture to shortening mixture, beating on low speed after each addition just until mixture is combined.
  3. Spoon batter into prepared muffin tins, filling each about two-thirds full. Use the back of a spoon to smooth out batter in cups.
  4. Bake for 15 to 18 minutes or until tops spring back when lightly touched. Cool cupcakes in muffin cups on wire racks for 5 minutes. Remove cupcakes from muffin cups. Cool completely on wire racks.
  5. Time to make your frosting while the cupcakes cool.
White Chocolate Frosting


  • 1 cup vegan butter, softened (Earth Balance)
  • 6 ounces white baking chocolate with cocoa butter, chopped
  • 1/3 cup rice whipping cream
  • 1 1/2 – 2 cups powdered sugar
  1. Place white baking chocolate in a large mixing bowl; set aside. In a small saucepan heat whipping cream just until simmering. Pour over white baking chocolate; let stand, without stirring, for 5 minutes. Stir until smooth; let stand for 15 minutes.
  2. Gradually beat butter into melted white chocolate mixture with an electric mixer on medium to high speed, beating until combined. Gradually beat in powdered sugar until frosting reaches piping or spreading consistency
  3. Divide frosting between two bowls. Tint one portion with green food coloring. Spoon each frosting into a pastry bag fitted with a large star tip. Pipe white and green frostings onto tops of completely cooled cupcakes to resemble four-leaf clovers or whatever decoration you’d like!
