GFCF Sandbox Cake

This recipe was recently featured in a Penzey's catalog. You can find the original recipe, which is called Cinnamon Supper Cupcakes, here. I like the name Sandbox Cake better - the kids think it's cute. I made this in a baking dish and served it as a coffeecake. It turned out so good that not even the crumbs lasted long. 1 cup GF flour blend 1 1/2 tsp. baking powder 1/2 tsp. xanthan gum 1/4
