Ingredients
  

For the Blueberry Oatmeal Bars

  • ½ cup all-purpose flour or use a 1:1 gluten-free flour blend for a gluten-free option
  • 2 cups quick-cooking oats gluten-free if needed
  • ½ cup brown sugar packed; dark brown sugar adds a richer flavor
  • ¼ tsp salt A hint of salt enhances the sweetness
  • ¾ cup butter melted and cooled; use unsalted butter for better control
  • 2 cups fresh blueberries or substitute with thawed and drained frozen blueberries
  • ½ cup sugar or coconut sugar for a healthier alternative
  • 1 tbsp lemon juice to brighten the blueberry flavor
  • 1 tbsp cornstarch helps thicken the filling

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • Prepare an 8-inch square baking pan by buttering or spraying it with cooking oil, or line it with parchment paper for easy cleanup.
  • In a large mixing bowl, combine the oats, flour, brown sugar, and salt. Stir until blended.
  • Pour in the melted and cooled butter and stir until combined and crumbly.
  • Press half of the oat mixture into the prepared pan to form a solid crust.
  • In another bowl, combine the blueberries, lemon juice, sugar, and cornstarch, and toss gently to combine.
  • Spread the blueberry mixture evenly over the crust.
  • Sprinkle the remaining crumble mixture over the top of the blueberries.
  • Bake for 40-50 minutes until the topping is golden and the filling is set.
  • Allow to cool completely on a wire rack before slicing.

Notes

Store bars in an airtight container at room temperature for up to 3 days. For best flavor, serve warm with ice cream or whipped cream.
