Combine cookie ingredients in a medium bowl. Use a medium cookie scoop to scoop dough onto a silicone lined baking sheet.
Bake in a 350 degree oven for 11-13 minutes and allow them to cool completely on the baking sheet.
Combine the frosting ingredients. Divide in half and add cocoa powder to half of the frosting.
Turn cookies over so the the bottom of the cookie is the top. Frost half of the cookie with vanilla frosting.
Frost the other half of the cookies with the chocolate frosting. Allow the cookies the set up and serve.
