Ingredients Notes:

Photos of the apple crumble bars ingredients.
  • Gluten Free Flour Blend – I tested this recipe with King Arthur Measure for Measure Flour blend. Other blends should work, but you may need to adjust the moisture level of the dough.
  • Xanthan Gum – If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon. See the substitutions section below for a gum-free alternative.
  • Ground Cinnamon and Nutmeg
  • Apples – There are so many great apples for baking! There are so many apples that will make your desserts incredible! My favorites include Fuji, Granny Smith, Jonagold, and Macintosh.
  • Brown Sugar – You can also use coconut sugar if you prefer.
  • Cane Sugar
  • Baking Powder – Use aluminum-free
  • Butter – Use unsalted butter.
  • Egg – Size large.

Substitutions:

  • To make this recipe dairy-free, use plant-based butter.
  • You can swap apple pie filling for the apples, cinnamon, and brown sugar.
  • If you can’t have xanthan or guar gum, make this gum-free recipe using my DIY Gluten Free Flour Blend. It uses psyllium husk instead of gums as a binder.

Fun Variations:

  • Feel free to change things up! You can add chopped nuts, raisins, or other fruit like blueberries and certified gluten-free oats to the crumb topping!
  • Use other fruits like peaches or strawberries.

Tips For Sucess:

  • Be sure to grease your baking pan to prevent the crust from sticking.
  • Preheat your oven before putting the bars in to bake. Also, set the oven rack to the middle position in the oven.

Recipe Step-By-Step Instructions:

Step 1: Peel your apples. You can use a vegetable peeler, or apple corer to do this. Place the peeled apple onto a cutting board and cut the apple into small pieces. Put them into a mixing bowl.

Step 2: Pour your diced apples into a large mixing bowl and add the brown sugar and cinnamon. Mix well to coat all of the apples.

Step 3: In a large bowl, add the dry ingredients. Whisk to blend them. Add the cold butter and use a pastry blender to cut in the cold butter so that you have a crumby mixture.

🔑 Sandi says: You can also freeze the butter and use a large grater to grate the frozen butter into small bits.

Step 4: Mix the egg and water into a soft dough. Your crust dough will look like the photo above.

Don’t forget that every gluten free flour blend has a different starch-to-grain ratio, and you may need to add more or use less liquid. You will know you added enough moisture if you use your hands and squeeze the dough. It should hold its shape.

Step 5: Dump ⅔ of the crust mixture into a parchment paper-lined 8×8 baking tin. Use a spoon or your hand to press the crust down firmly so that it is flat.
