Gluten Free Oats

Almond Flour

Adds richness and a tender crumble texture. For nut-free, use oat flour.

Brown Sugar or Coconut Sugar

Butter or Coconut Oil

Creates crisp golden edges. For a dairy free version, use vegan butter or coconut oil.

Vanilla and Cinnamon

  • A spoonful of gluten free flour

Step 4: Add Topping

Sprinkle evenly over the apples.
Ensure no apples peek through a full oat layer ensures a crisp golden top.

Step 5: Bake

  • Vanilla ice cream
