Gluten Free Spice Cake** (see notes for how to bake using gfJules Best Gluten Free Cake Mix)
Pre-heat oven to 325º F (static). Bring eggs and milk to room temperature.
Spray two 8- or 9-inch round cake pans with non-stick cooking spray and dust entire surface lightly with gfJules™ All-Purpose Gluten Free Flour (line bottom with parchment paper, if desired). To make cupcakes, oil or line cupcake pans with cupcake papers (Makes approximately 28 cupcakes).
Whisk together the flour, powdered pudding mix, baking powder, salt, sugar and spices in a large mixing bowl. Cut cold butter into small pieces and add to bowl.
Using flat paddle attachment on a stand mixer or hand mixer with beaters, work butter into the dry ingredients until the mixture is crumbly.
In a separate bowl, mix eggs, egg whites, vanilla paste and buttermilk (or milk + lemon juice).
Slowly add the liquid mix to the dry mix, beating just until smooth (not more than 1 minute).
Pour into the prepared pans and smooth tops with a rubber spatula.
For cakes, bake for 40 minutes; for cupcakes, test after 20 minutes for doneness; for sheet pan, approximately 40-42 minutes. To test the cakes for doneness, insert a cake tester or toothpick in the middle of each cake and be sure it comes out clean, with very few dry crumbs attached. The cakes will also begin to pull away slightly from the sides of the pans. Add time if necessary to fully bake the cakes.
When done, turn off the oven and leave the oven door open to let the cakes cool slowly there for 3-5 minutes, then remove the cakes to a cooling rack. After 15-20 minutes of total cooling time, gently invert the cakes to remove them from the pans, then flip gently back onto the cooling rack until fully cooled. (No need to remove from pans if baking in a sheet pan.)
Maple FrostingCream shortening with maple syrup, vanilla and sifted confectioner's sugar until light, but spreadable. If using butter, it may be necessary to add more confectioner's sugar so the frosting isn't too thin; if using shortening, more milk may be necessary to achieve a spreadable consistency.
