Preheat oven to 350 degrees and line a cupcake tin with St. Patricks day themed cupcake liners.
In a standing mixer or large bowl, combine dry ingredients with the butter and mix together on low for a minute or two.
Add eggs, one at a time, and continue to mix on low speed until combined before adding other egg.
Gradually add in the mint, vanilla, and milk and mix until all combined.
Add in a few drops of the color and mix. Add in a few more to get the color that you want.
Fill cupcake liners about 3/4 of the way and bake in the oven for 21 minutes. When done, set aside.
