Equipment

  • 8x8-inch baking dish
  • Parchment Paper
  • Food processor (or pastry cutter)
  • Large Mixing Bowl

Ingredients
  

For the Crust and Crumble

  • 2 cups certified gluten-free rolled oats specifically labeled gluten-free
  • 1 cup gluten-free flour blend with xanthan gum
  • 1/2 cup coconut sugar or brown sugar
  • 1/2 tsp sea salt
  • 1/2 tsp ground cinnamon
  • 1/4 tsp nutmeg
  • 3/4 cup cold unsalted butter cubed (or coconut oil for dairy-free)
  • 1 tsp vanilla extract

For the Apple Filling

  • 4 medium apples Honeycrisp or Granny Smith (about 4 cups sliced)
  • 2 tbsp fresh lemon juice
  • 3 tbsp maple syrup or honey
  • 2 tbsp cornstarch or arrowroot powder
  • 1 tsp ground cinnamon
  • 1/4 tsp ground cardamom optional
  • 1/4 tsp ground ginger

Instructions
 

  • Preheat your oven to 350°F (175°C). Line an 8×8 inch baking dish with parchment paper, leaving some overhang on the sides for easy removal later.
  • In a food processor, pulse the gluten-free oats a few times to break them down slightly. Add the gluten-free flour, coconut sugar, salt, cinnamon, and nutmeg, pulsing to combine. Add the cold cubed butter and vanilla extract, then pulse until the mixture resembles coarse crumbs.
  • Take about 2/3 of the crumble mixture and firmly press it into the bottom of your prepared baking dish, creating an even layer. Use the bottom of a measuring cup to compact it. Place this in the refrigerator while you prepare the apple filling.
  • Peel, core, and thinly slice the apples (about 1/4 inch thick). In a large bowl, toss the apple slices with lemon juice, maple syrup, cornstarch, cinnamon, cardamom, and ginger until thoroughly coated. Let this mixture sit for 5-10 minutes.
  • Remove the chilled crust from the refrigerator. Arrange the apple mixture evenly over the crust, including any accumulated juices. Sprinkle the remaining crumble mixture over the apples, gently pressing to adhere.
  • Bake for 35-40 minutes until the topping is golden brown and the apple filling is bubbling at the edges.
  • Allow the bars to cool in the pan for at least 30 minutes, then transfer to the refrigerator for another 30 minutes. Cut into 16 squares and serve.

Notes

For best results, let the bars cool completely before cutting for cleaner slices.
Store in an airtight container at room temperature for up to 2 days, or refrigerated for up to 5 days.
These bars freeze well for up to 3 months. Simply wrap individual portions in parchment paper and store in a freezer-safe container.
For a dairy-free version, substitute the butter with solid coconut oil or plant-based butter alternative.
