Recipe Notes

  • Xanthan Gum is a thickening and stabilizing agent often used in gluten-free baking to provide structure to baked goods that typically comes from gluten. Xanthan gum is also used in sauces and dressings to help thicken and emulsify ingredients. It can be found in the grocery store with the gluten-free baking ingredients or online.
  • To prepare sweet potatoes, pierce whole sweet potatoes multiple times with a fork and bake at 350° F. for 45 minutes, or until soft to the center.
  • Store leftover cookies in an airtight container for up to 5 days.
