I kind of combined a few different recipes and came up with this. I love the combination of mint and chocolate and just had a couple bags of Mint M&M's in my baking cabinet.
1 cup plus 2 tablespoons unsalted butter, room temp
1 cup sugar
1 cup light brown sugar
2 eggs, room temp
2 teaspoons vanilla extract
2 1/2 cups all-purpose flour
3/4 cups unsweetened cocoa powder
1 teaspoon baking soda
1/2 teaspoon salt
2 cups of Mint M&M's (a bag and half)
Preheat oven to 350 degrees.
Add butter and sugars to a large bowl, turn a hand mixer to medium speed and beat until creamy, light and fluffy.
Add eggs one at a time until well combined. Add vanilla
In a separate bowl,sift together the flour, cocoa powder, baking soda and salt.
With the a mixer on low, slowly add the dry ingredients to the wet ingredients, scraping down the sides of the bowl as needed. The cookie batter will become very thick. You only need to mix until everything has combined.
Stir in the Mint M&Ms.
Drop cookie dough by medium cookie scoopfuls onto cookie sheets. Bake 9 to 12 minutes or until the cookies have puffed a little and the tops are dry.
Cool on baking sheets for 5 minutes then transfer to a cooling rack and cool completely.
When these are warm they are gooey like brownies. These also came out great!
