The Best M&M Cookies

0 Preheat the oven to 350°F. Line a baking sheet with parchment paper or a nonstick baking mat.
1 In the bowl of a stand mixer (or a large with a hand mixer), cream the softened butter, granulated sugar and dark brown sugar together until light and fluffy, about 5-6 minutes.
2 Add the eggs to the batter, and measure in the vanilla extract. Beat until smooth.
3 Next, measure the flour, baking powder and salt into the bowl. Start blending on a low speed, then turn up the speed until the batter is smooth and combined.
4 Measure in the M&M's (and any other additions you might want to add like mini chocolate chips, etc.) Stir them into the batter using a rubber spatula.
5 Use a cookie scoop to scoop the cookies onto the prepared baking sheet, giving about 2" of space between each one so the dough can spread as it bakes. Press a few additional M&M's on to the tops of the cookies.
6 Bake for 12-13 minutes, or until the cookies are set, and remove from the oven.
7 Cool on a wire cooling rack, and then enjoy!
