Frosted sugar cookies. I don’t have the recipe where I can get to it right now. Any good sugar cookie recipe will do. The fun is in frosting them. You roll the cookie dough out and cut it in various Christmas shapes, and bake them. Skip the part where you sprinkle them with sugar. Have several bowls of different colored frosting, sprinkles, candies, colored sugar, etc. You need a lot of room to lay the frosted cookies out to dry.
My brother used to do those. He’d mix up a dozen different colors of icing and handpaint each one.
