Ingredients Method Notes

Ingredients
  

  • 2 cups rolled oats
  • 1 cup all-purpose flour
  • 1/2 cup brown sugar
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter melted
  • 2 cups fresh blueberries
  • 1/4 cup granulated sugar
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch

Method
 

  1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.
  2. Prepare the Crust: In a bowl, mix together oats, flour, brown sugar, baking powder, and salt. Add melted butter and mix until crumbly. Press half of the mixture firmly into the bottom of the prepared pan.
  3. Make the Blueberry Filling: In another bowl, combine the blueberries, granulated sugar, lemon juice, and cornstarch. Gently stir to coat the blueberries with the mixture.
  4. Assemble the Bars: Spread the blueberry filling evenly over the crust in the pan. Sprinkle the remaining crumble mixture on top of the blueberries.
  5. Bake: Bake for 30-35 minutes, or until the top is golden brown and the blueberries are bubbling.
  6. Cool and Serve: Let the bars cool completely in the pan before cutting into squares. Serve and enjoy!

Notes

You can swap the blueberries for other fruits like raspberries or blackberries for a different flavor profile. Use a gluten-free all-purpose flour blend in place of the regular flour to make this recipe gluten-free. Store any leftover bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. These bars are great served with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.
