Enjoy this Peach Walnut Crisp for a sweet (and healthy) treat!


  • 4 large peaches, peeled, pitted, and sliced
  • 1 1/2 tablespoons arrowroot starch (or cornstarch)
  • 2 teaspoons cinnamon, divided
  • 1/3 cup rolled oats
  • 1 cup walnuts, chopped
  • 2 tablespoons oat flour
  • 2 tablespoons coconut sugar
  • 1/8 teaspoon salt
  • 2 tablespoons maple syrup
  • 2 tablespoons coconut oil (not melted)


  1. Preheat oven to 350 degrees F. Coat an 8-inch baking dish with cooking spray. Set aside.
  2. In a large bowl, gently toss peach slices with arrowroot and 1/2 teaspoon cinnamon until evenly coated. Pour in an even layer at the bottom of the baking dish.
  3. In another bowl, combine the rolled oats, walnuts, oat flour, coconut sugar, and salt. Stir to combine. Mix in the maple syrup and coconut oil. Knead with the back of a fork or finger to create a crumb-like texture. Evenly layer on top of the peach slices in the baking dish.
  4. Bake in the oven for 30 minutes, until crumble is golden brown.
  5. Remove from oven and let cool for at least 30 minutes on a cooling rack. This will allow the peach mixture set.
