Gluten-Free Blueberry Crumble Bars

Gluten-free Blueberry Crumble Bars are the perfect breakfast or dessert option. Making these with fresh blueberries is the perfect summer treat! I think these would also be great with other berry mixtures as well – perhaps even some rhubarb!

Servings 9 servings

Ingredients
  

For Base & Crumble Topping

  • 1 cup gluten-free flour
  • ¾ cup gluten-free rolled oats
  • ½ cup sugar
  • ¼ cup packed brown sugar
  • ½ tsp cinnamon
  • ¼ tsp salt
  • ½ cup dairy-free butter melted
  • 1 large egg yolk
  • 1 tbsp packed brown sugar

For Blueberry Layer

  • 2 cups blueberries fresh or frozen
  • 2 tbsp lemon juice
  • ¼ cup sugar
  • 2 tsp cornstarch

Instructions
 

  • Preheat the oven to 350 degrees. Line an 8×8 baking pan with foil and grease with cooking spray.
  • In a medium bowl whisk together the flour, oatmeal, granulated sugar, 1/4 cup brown sugar, cinnamon, and salt. Gently stir in the melted butter & egg yolk. 
  • Remove 1 cup of the mixture.
  • Press the remaining mixture into the bottom of the prepared pan. 
  • In a medium bowl mix together all the ingredients for the blueberry layer. Spoon over top of the base oatmeal cookie mixture in the pan. 
  • To the reserved 1 cup of oatmeal mixture, stir in the 1 additional tablespoon of brown sugar. Crumble the mixture over top of the blueberry layer.
  • Bake in the preheated oven for about 40-45 minutes or until you see the blueberries bubbling and the top crumble turning golden brown. If you used frozen berries, the bake time will be 50-55 minutes. 
  • Allow to cool fully to room temperature (at least 3 hours) before cutting into the bars. Bars are easiest to cut when they're cold using a sharp knife.
