There are two Rolls in the box take one for decoration and one for smashing I used six boxes so depends on how many boxes you have I just gave a cookie per cupcake.
Chocolate Cupcakes
1 cup water
1/2 cup unsweetened cocoa powder
1 and 1/3 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt
1/2 cup unsalted butter, softened to room temperature
1 cup sugar
2 large eggs
2 teaspoons pure Mint extract
1 whole package of Mint Smashed Girl Scout cookies
Mint Girl Scout Frosting
1 cup (2 sticks) unsalted butter, softened to room temperature
3-4 cups powdered confectioners sugar
2 Tablespoons heavy cream
1/4 teaspoon peppermint extract
2 drops green food dye
pinch of salt, as needed
2 teaspoons pure Mint extract
Preheat oven to 375F degrees. Line 14 muffin cups with liners.Over high heat, bowl the water in a small saucepan. Pour the unsweetened cocoa powder into a medium sized bowl and mix with boiling water until smooth. Allow to cool to room temperature by placing in the refrigerator as you prepare the other ingredients. Whisk together the flour, baking powder, and salt in a medium sized bowl. Set aside. In a large bowl, using an electric hand or stand mixer, cream the softened butter and sugar until light and fluffy. Add the eggs, one at a time, beating until smooth. Scrape down the sides of the bowl as needed. Beat in the Mint extract. Slowly add the flour mixture and beat only until just combined. In a steady stream, add the cocoa mixture and stir until smooth then add the smashed girl scout cookies. Fill each muffin tin 3/4 of the way full with batter. Bake for 16-19 minutes keep a eye on them to avoid burning which will end up dry cupcakes. My cupcakes took 15 minutes and a toothpick inserted in the middle came out clean. Remove from oven and place on a wire rack to cool before frosting. beat softened butter on medium speed with an electric mixer. Beat for about 30-60 seconds until smooth and creamy. Add 3 cups of powdered sugar, cream, peppermint extract, and food coloring. Increase to high speed and beat for 3 minutes. Add more powdered sugar if frosting is too thin up to 4 cups or more cream if mixture is too thick add salt if the frosting is too sweet. You may also add more food coloring if needed or more mint extract if it is not minty enough. Stir in the mint Girl Scout Cookies by hand Frost cooled cupcakes there might be leftover frosting depending how much you use on each cupcake. Also take second roll of Girl Scout Cookies in half and shove cut half in to frosting to let theme know the cupcake is infused with little chunks of girl scout cookies.
Side Note:Replacing heavy cream in the frosting with milk or half-&-half will result in a not so creamy consistency.
