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

Print Friendly Version

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.

    No milk
    Also I did not add a garnish

  2. Maple Walnut layer Cake

    This cake was AMAZING!!! I have never baked a cake from scratch, let alone Gluten Free and FODMAP friendly, that came out this great. I cannot recommend this cake enough. It is SO good. A very dense and moist cake. I did not have any maple extract so I used vanilla and a bit of Almond. In the frosting I used maple sugar from a girlfriend and her husbands maple business. It was totally to die for.. Thank you SO much!

  3. Gluten free maple walnut cake

    Hi. I made cupcakes. I felt there was too much sugar in the recipe so I only used 1 cup. The batter was too thick so I used 2 cups of milk instead. They were delicious.

    1. Thanks so much Michelle!
      We love hearing feedback and when our customers make changes that suit their personal preferences 🙂

  4. Hi there, I’m wondering if it’s possible to use maple syrup instead of maple extract in the cake batter? Should I decrease the sugar and almond milk to accommodate for the extra sugar and moisture?

    1. Hi Leah,
      Maple syrup is very subtle in flavor and will not create the same effect as the maple extract. You will also want the extract for the frosting to taste like maple as well. We have not tried your substitution and would not be able to tell you how it would work without testing the recipe. The gluten-free baking process may be trickier than standard baking. Thanks for your question 🙂
