Let's walk through the steps to create a Red, White, and Blue Sugar Cookie Pie you'll be proud to serve, and that will be devoured in no time! These are the basic steps—follow the recipe below for all the specifics.
1. Prep
Heat your oven to 350°F for even baking. Lightly spray only the bottom of your 9-inch pie plate with cooking spray for easy release.
2. Make
In a large bowl, combine cookie mix, softened butter, egg, and flour; stir until a soft dough forms. Gently fold in M&M's® and initial sprinkles. Press dough firmly and evenly into the pie plate.
3. Bake
Bake for 20 minutes, or until edges are golden. Cool completely on a wire rack for 30 minutes.
4. Decorate
Combine sifted powdered sugar, softened butter, vanilla, and 2 tbsp milk; beat 3 minutes until light and airy, adding more milk (1 tsp at a time) for desired consistency. Spread on completely cooled pie, top with sprinkles, slice, and enjoy!
