Coffee Cake- gluten free!

Ok- so here's another gluten free recipe.  A friend of mine had a post on Facebook this morning- "making coffee cake for breakfast"...  I decided that sounded REALLY good, so found a recipe on www.allrecipes.com for regular coffee cake.  I figured I could make it gluten free- with a few adjustments of course! :)  Here it is! :)

Gluten Free Streusel Coffee Cake

3/4 C white sugar
1/4 cup shortening (I used butter!)
2 eggs
1/2 C half and half
1 tsp vanilla
1/4 C potato starch
1/4 C tapioca flour
1/2 C white rice flour
1/2 C brown rice flour
2 1/2 tsp baking powder
1/2 tsp salt

Topping:
1/2 C brown sugar
2 Tbsp white rice flour
2 tsp ground cinnamon (I put in more, of course!)
1/2 C chopped walnuts (I didn't have any, so I omitted them and it turned out pretty good, although I'm sure it would be better with the nuts)
2 Tbsp butter, melted

Preheat  oven to 375.  Grease and flour a 9x13 inch baking pan.  Cream together the white sugar adn shortening.  Beat in eggs one at a time.  Stir in vanilla and half and half.  In a separate bowl, sift together flour, baking powder and salt.  Stir flour into cream/egg mixture.  In a small bowl stir together brown sugar 2 tablespoons flour, cinnamon and walnuts.  Stir in melted butter.  Spread half the cake batter in bottom of prepared pan.  Sprinkle half of the streusel mixture over the batter.  Spread the other half of the batter of the streusel mixture and top off with the rest of the streusel mix.  Bake in preheated oven for 25-35 minutes until a toothpick inserted into center of the cake come out clean.

Enjoy! :)
