Growing up I have the fondest memories of making apple pie with grandmother. She would always make a regular-sized apple pie, and I would use the leftover crust and filling to make a mini version. Apple pie is a classic all American dessert, served at many family gatherings. Though delicious, apple pie does take a bit of time and patience to make. Which is why this recipe is perfect because you get all of the apple pie flavors without having to make a tedious pie crust. Simple, straight forwarded ingredients, with the taste of maple caramelized apples that melt in your mouth. These Gluten-Free Apple Crumble Bars will become a forever Fall favorite!

3 Layers to Gluten-Free Apple Crumble Bars

These bars are made with 3 simple layers:

  • Shortbread Crust: This paleo shortbread crust is made with both almond and coconut flour, flavored with real maple syrup, coconut oil, vanilla, and a pinch of salt. Mix all the ingredients in one large bowl, and reserve a quarter of the crust for the crumble topping. No chilling or rolling of the dough is required. This is a huge time saver!
  • Apple Layer: Fresh juicy apples caramelized with maple syrup and coconut sugar.
  • Pecan Crumble Topping: A quarter of the reserved crust, a few tablespoons of candied pecans for crunch and add a sprinkle of cinnamon for flavor. No separate streusel recipe is needed!

Tips for Making the BEST Gluten-Free Apple Crumble Bars

  • Do not underbake the shortbread layer, as it provides support for the filling. I find 12-14 minutes tends to be the perfect amount of time.
  • Chill the bars, preferably overnight for best results.
  • For those without dairy allergies, you can use butter or ghee in place of the coconut oil.
  • You can use cornstarch in place of the arrowroot powder.
  • Brown sugar for coconut sugar for non-paleo versions.
  • Candid pecans provide the best flavor!
  • Serve straight from the refrigerator.

Shortbread Crust

  • 2 cups almond flour
  • 2 tablespoon coconut flour
  • 1/3 cup melted coconut oil, ghee or butter
  • 1/3 cup maple syrup
  • 1/2 teaspoon vanilla
  • 1/4 teaspoon salt

Apple Filling

  • 3 cups diced apples 2 large apples
  • 1/4 cup maple syrup
  • 2 tablespoons water
  • 2 tablespoons coconut sugar
  • 1 tablespoon melted coconut oil, ghee or butter
  • 2 teaspoons arrowroot powder
  • 2 teaspoons cinnamon
  • 1 tsp lemon juice
  • 1 teaspoon vanilla
  • 1/8 teaspoon salt

Crumble Topping

  • 1/4 remaining shortbread mixture
  • 4 tablespoon chopped candied pecans
  • 1/4 teaspoon cinnamon


  • Preheat the oven to 350°. Grease and line a 9x9 inch square pan with parchment paper. Set aside.
  • In a large bowl mix all of the shortbread ingredients: almond flour, coconut flour, maple syrup, melted coconut oil, maple syrup, vanilla and salt.
  • Reserve 1/4 of the mixture for the crumble topping. Take the remaining mixture and gently press it down in the lined square pan. Bake for 12-14 minutes, or until lightly brown around the edges. Once the crust is fully cooked, remove from the oven and set aside.
  • While the shortbread is cooling start the apple layer. Dice the 2 large apples into small cubes and transfer to a large bowl. Add the remaining maple syrup, melted coconut oil, arrowroot powder, cinnamon, salt, vanilla, and lemon juice. Stir the mixture until the apples are evenly coated.
  • Pour the apple mixture into a large saucepan and add 2 tablespoons of water. Cook on medium heat, while continuing to stir, until sauce begins to thicken. Apples will begin to caramelize at about 5-7 minutes.
  • Once the apples have caramelized turn off the heat and carefully pour the apple mixture over the top of the shortbread crust, spreading evenly.
  • Take the reserved shortbread dough and toss in the chopped pecans and cinnamon, creating a crumb-like mixture. Sprinkle the crumble topping evenly over the caramelized apples, then gently press down with a fork to secure.
  • Return the pan to oven and bake for 20-25 minutes, or until the crumble topping is golden brown.
  • Remove the pan from the oven and allow the bars to cool for 30 minutes. Then transfer the bars to the refrigerator for at least 4 hours, (or overnight).
  • Cut the bars into 16 squares, serve immediately.
  • Bars can be kept in the refrigerator for up to 5 days.
