Preheat oven to 350* F. Grease two 8-inch round cake pans with shortening or pan spray and insert a parchment circle into the bottom of each pan.
In a large bowl, combine sugar, non-dairy milk, oil, applesauce and vanilla with a whisk.
1 ½ Cup Granulated Sugar, 1 ¼ Cup Non-Dairy Milk, ⅔ Cup Canola Oil, ½ Cup Unsweetened Applesauce, 2 teaspoon Vanilla Extract
Sift the gluten-free flour, cocoa powder, oat flour, baking powder, salt, xanthan gum, and baking soda together, then add them into the wet ingredients. Whisk well to form the batter. Whisk for about 1 minute.
1 ½ Cups King Arthur Gluten-Free All-Purpose Flour, 14 tablespoon Dutch Processed Cocoa Powder, 2 tablespoon Oat Flour, 2 teaspoon Baking Powder, 1 teaspoon Kosher Salt, ½ teaspoon Xanthan Gum, ¼ teaspoon Baking Soda
Divide the batter between the prepared cake pans. If you have a kitchen scale, it will be about 20 ounces per pan.
Bake in a 350* oven for 29-31 minutes or until a toothpick inserted into the center of the cakes comes out clean.
Allow to cool completely before frosting.
