Ingredients

  • 6 medium baking apples, peeled, cored and sliced Honeycrisp, Granny Smith, Jonagold
  • 1 teaspoon ground cinnamon
  • ¼ cup maple syrup
  • ½ cup cane sugar
  • ½ cup cold vegan butter
  • 1 ½ teaspoons pure vanilla extract divided
  • 1 cup gluten-free oat flour
  • ¼ teaspoon salt
  • 1 tablespoon + ¼ cup arrowroot starch divided

Instructions

  • Preheat the oven to 350 degrees Fahrenheit. Grease a 1.5-2 quart baking dish with cooking spray or extra vegan butter.
  • Place apples into a large mixing bowl and toss with 1 tablespoon arrowroot starch and the cinnamon. Add maple syrup and 1 teaspoon vanilla, stir to coat.
  • Transfer apple mixture to prepared baking dish.
  • Clean out the mixing bowl and add organic cane sugar and vegan butter. Cream with an electric mixer. Then, with a couple forks or a pastry cutter, blend in remaining vanilla, the oat flour, ¼ cup arrowroot starch, and the salt until the mixture is crumbly. 
    Once flour and starch are thoroughly integrated, use your hands to form smaller crumbles and then cover the apples evenly with the crumble mixture.
  • Bake for 45-50 minutes until golden and bubbly.

Notes

Only have gluten-free oats on hand? You can make your own oat flour easily in a food processor.
Storing: Wrap foil over the baking dish or place in an airtight container in the refrigerator for 3-4 days.
To reheat the whole dish, allow the crumble to sit at room temperature for about 20 minutes before heating it in a 300-degree Fahrenheit oven until warm. Tent the baking dish with foil so that the topping does not brown too much.
To reheat portions, place an individual portion in a microwave-safe bowl and heat for 30-second intervals until warm. This method will soften the topping.
