Preheat oven to 350, Grease and dust with flour one 8 or 9 inch cake pan.
Whisk together dry ingredients in a medium bowl until combined.
Add wet ingredients, mix until smooth, and pour batter into prepared cake pan.
Bake 30-35 minutes, until a toothpick comes out clean. Allow to cool completely before removing from pan. Frost with frosting of your choice, or drizzle with a glaze made by whisking 3 tbsp orange juice with 1/3 cup powdered sugar.
