Low-FODMAP Maple Walnut Layer Cake with Low-FODMAP Maple Buttercream Frosting; Gluten-free, Dairy-free

I love maple syrup- it is my go-to sweetening ingredient for almost all my  low-FODMAP recipes.  And it is heavenly in a low-FODMAP cake recipe!

This low-FODMAP Maple Walnut Layer Cake is light, moist, spongy and so delicious.  It is perfectly crowned with the low-FODMAP Maple Buttercream. Low-FODMAP Maple Buttercream Frosting is also a supreme topping for my low-FODMAP Zucchini Spice Cake.
