Preheat the oven to 350F degrees. Line your cupcake pan with cupcake liners. Set aside.
In a medium bowl, whisk together flours, baking powder, and salt. Set aside.
In a large bowl using an electric mixer, cream sugar and butter for two minutes. Add eggs one at a time, mixing slowly after each addition.
Slowly add flour mixture to wet ingredients, alternating between flour mixture and milk; beat at low speed until just combined. Add vanilla extract and mint extract, as well as desired amount of mint green food coloring, mixing on low speed until just combined. Do not overmix.
Scoop batter into cupcake liners – no more than ⅔ full, or use a #24 disher to scoop batter. Bake for 15-20 minutes. Check cupcakes around 15 minutes to avoid over-baking. Insert a toothpick into the center of the cupcake, if it comes out clean it is done. Remove cupcakes from the oven and allow cupcakes to cool in cupcake pan for 5 minutes; transfer to a wire rack to cool completely. Cupcakes should be cooled completely before frosting.
