Low-FODMAP & Gluten-free White Chocolate Macadamia Oatcakes

I have been staring at packages of oat cakes at the grocery store and could not wait to try a recipe for these myself.

I love the idea of a healthy sweet and salty treat, that goes great for breakfast or dessert.

Oat ‘cakes’ are more of a cookie (or “biscuit”) than a cake, and are common in Scotland as well as parts of Canada.  My version is cut in rectangles, like they do in Nova Scotia.  However, you could easily make them round if you prefer.

If you want to flavor your oat cakes like a cookie (my preference), then try my version with white chocolate and macadamia.  But if you want to decrease the sugar, you can make these plain, and they will still be amazing.

FODMAP fact: Oats are low in FODMAPs, but old-fashioned oats have the largest allocated serving size of the different varieties. You can have 1/2 cup of uncooked old-fashioned oats during the elimination phase.  In contrast, steel-cut oats (or groats) and ‘quick’ oats are low in FODMAPs at servings of 1/4 cup; still an ample amount for a filling meal.  For this recipe, I recommend sticking to the old-fashioned variety!

  • Bake for 15-20 minutes until they are golden brown and crisp
  • Separate the sections along the score lines with a thin knife or spatula and then allow them to cool completely on a wire rack

  • Old fashioned rolled oats are low-FODMAP in 1/2 cup servings, do not substitute quick oats
  • Butter is naturally low in lactose and FODMAPs
  • You may also use butterscotch chips (similar to white chocolate in ingredients), or semisweet chocolate chips.  White chocolate is low-FODMAP in 25g servings
