We used Bob's Red Mill GF All-Purpose Baking flour in place of our homemade GF flour blend in the original recipe to make it more accessible to bakers who may not want to invest in the ingredients to make your own blend. The beauty of this cake is it is perfectly customizable. We recommend baking, preparing and assembling as directed because the balance between nutty, toasty gluten free vanilla cake with the fruity, juicy and tangy strawberry preserve, topped off with the cream cheese frosting is perfection for us! The cake itself is delicious, moist and flavorful with a slightly dense, moist crumb that is uniform and falls apart slightly easily. The cream cheese vanilla frosting is slightly sour but creamy, sweet and pleasantly vanilla flavored. Enjoy!
