<<Disclaimer: Verify this information before applying it to your situation.>> Dear Listmembers, I have a very tasty recipe for a cake that I make frequently. Strauss Waltz Butter Cake 1/2 cup potato starch flour 1/2 cornstarch 1 cup minus 2 tablespoons rice flour 1 tablespoon baking powder 2 teaspoons xanthan gum 1 cup butter, or if lactose free, use soy margarine, as I do 1 1/4 cups sugar 4 eggs 2 teaspoons vanilla 1 teaspoon almond extract, if desired, I have used banana extract and it was delicious Preheat oven to 375. Sift together potato starch flour, cornstarch, rice flour, baking powder and xanthan gum. Set aside. Cream butter and sugar, beating until light and smooth. Add dry ingredients, 1/2 cup at a time, alternating with an egg each time. Beat well after each addition. Add vanilla and almond extract and beat well. Pour into 10" greased tube pan spreading the batteer very evenly. Bake 40 minutes or until cake tester comes out clean. Remove from pan, after waiting about 10 minutes. Cool and sprinkle with confectioners sugar, if desired. Happy Holidays! Karen from Central NY, USA
