Add your dry ingredients and stir until just combined. Do not over mix. Batter will be very thick. Pour the batter into prepared pan, smooth it out as best as you can (It is thick) and bake for 20-25 minutes until a toothpick inserted into the center comes out clean. Err on the side of under baking if you are questioning. Once you remove the cake from the oven, make your icing by mixing all ingredients together until smooth. Pour the icing over top of the still very warm cake. Cool completely, cut and serve.
