Preheat oven to 350 degrees F. Line a large baking sheet with parchment paper (I didn't line mine, I sprayed it with Pam, and they still came out fine).
For the chocolate cookies: place the butter, confectioners sugar and cocoa in a medium bowl and beat with an electric mixer set on medium speed until fluffy, about 2 minutes. Combine the flour and baking powder in a small bowl. Beat the flour mixture into the butter mixture until well combined, about 2 minutes. Set aside.
For the strawberry cookies: place the butter and confectioners sugar in a medium bowl. Add 2 drops each of the food coloring and strawberry flavor/extract. Beat with an electric mixer set on medium until fluffy, about 2 minutes. Combine the flour and the baking powder in a small bowl. Beat the flour mixture into the butter mixture until well combined, about 2 minutes.
Roll both flavors of dough into 1-inch balls and place on the prepared baking sheet. Press the balls gently to flatten.
Bake the cookies until set, about 6-8 minutes. Transfer the cookies to a wire rack to cool.
For an extra special treat, dip these cooled cookies in melted white, dark, or milk chocolate. Place on a baking sheet lined with parchment paper and let stand until the coating is cooled and completely set.
