Ingredients Method Notes

Ingredients
  

For the Crust and Topping
  • 2 cups gluten-free all-purpose flour
  • 1 cup rolled oats
  • 1/2 cup brown sugar, packed
  • 1/2 cup granulated sugar
  • 1/2 teaspoon salt
  • 1 teaspoon baking powder
  • 1 cup unsalted butter, melted
For the Blueberry Filling
  • 2 cups fresh or frozen blueberries
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking pan or line it with parchment paper for easy removal.
  2. In a large mixing bowl, combine the gluten-free all-purpose flour, rolled oats, brown sugar, granulated sugar, salt, and baking powder. Stir until well mixed. Add the melted butter and mix until the crumbs resemble wet sand.
  3. Take about 1 cup of the crumb mixture and set it aside for the topping.
  4. In another bowl, toss the blueberries with lemon juice and cornstarch until the berries are coated well.
Assembly and Baking
  1. Press the remaining crumb mixture evenly into the bottom of the baking pan.
  2. Spread the blueberry mixture over the crust, then sprinkle the reserved crumb mixture on top.
  3. Bake in the preheated oven for about 25-30 minutes, or until the topping is golden brown.
  4. Once cooled completely, cut into bars and serve.

Notes

These bars can be enjoyed with whipped cream or a scoop of vanilla ice cream. Store leftovers in an airtight container at room temperature for up to 3 days or refrigeration can extend their life to a week. For freezing, wrap each bar in plastic wrap and place in a zip-top freezer bag.
