If you prefer to make your cake from scratch, I recommend Simple White Cake.
You can add 1/4 to 1/2 teaspoon maple extract to the frosting for more intense maple flavour. You could do the same to the cake batter. I would recommend cutting the bacon in half or thirds before wrapping it on!
You can make this as a 4-layer cake also. Slice cake layers horizontally in half using a long piece of dental floss or strong thread. You will also need to increase the amount of frosting you make by 50%.
I've wrapped bacon around the outside of the cake for decoration. You'll need an additional 5 slices bacon. I recommend cutting the bacon strips in half or in thirds to make cutting the cake easier.
