A beautiful layered Apple and Cinnamon Cake with Salted Caramel Cream Cheese Buttercream. This gluten-free apple cake is wonderfully flavourful and the depth of buckwheat rounds out the warmth of the cinnamon, allspice, cloves and nutmeg. The luxurious cream cheese buttercream spiked with homemade salted caramel turns this cake into a real celebration.
