Remember this cupcakes? Well, I made too much frosting. What to do with leftover frosting? Make cookies! I got the idea by googling it. It's very simple, just add 1 cup flour and 1 egg to 1/2 cup frosting. I had 1 cup frosting but didn't double the recipe, so the cookies are more chewy and moist. To make them more special, put oreos under every cookie dough balls, so during the baking the dough will spread and hide them. Cookies with a surprise inside!
