Using 100% vegetable shortening, grease and then flour two 9-inch round cake pans.
Sift dry ingredients together into large mixing bowl. Add remaining ingredients; beat with electric mixer at medium speed until smooth.
Pour batter into prepared cake pans. Bake in preheated 350 °F oven for 25 to 30 minutes, or until a wooden pick inserted into the middle of the cake comes out clean. Let cool in pans 10 minutes before turning out onto wire racks to cool completely. Frost.
Gluten: Gluten is a protein found in specific grains (wheat, spelt, kamut, barley, rye). Other grains are naturally gluten-free but may have cross-contact with gluten-containing grains. Look for certified gluten-free products if you need to avoid gluten. Find out more about wheat and gluten substitutions.
