Ingredients
  

Dry Ingredients

  • 1 cup old-fashioned oats for chewiness
  • 3/4 cup all-purpose flour (or gluten-free flour blend) for structure
  • 1/3 cup light brown sugar for sweetness and moisture
  • 1/4 teaspoon baking soda to help with rising
  • 1/4 teaspoon salt to enhance flavors
  • 1/2 teaspoon cinnamon (optional) for warmth

Wet Ingredients

  • 6 tablespoons unsalted butter, melted (or coconut oil) for richness
  • 1 teaspoon vanilla extract for flavor depth

Filling

  • 1 cup blueberries (fresh or frozen) for juiciness and flavor
  • 1/4 cup granulated sugar for added sweetness
  • 2 teaspoons cornstarch to thicken and stabilize filling

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease a baking pan.
  • In a mixing bowl, combine the old-fashioned oats, flour, light brown sugar, baking soda, salt, and optionally, cinnamon. Mix until well combined.
  • Melt the unsalted butter (or coconut oil) and mix it with the vanilla extract. Add this mixture to the dry ingredients and stir until well incorporated.
  • Press half of the oat mixture evenly into the bottom of the prepared baking pan.

Filling and Baking

  • In another bowl, combine the blueberries, granulated sugar, and cornstarch.
  • Spoon the blueberry mixture over the pressed oat base and spread it evenly.
  • Sprinkle the remaining oat mixture over the blueberry layer and gently pat into place.
  • Bake in the preheated oven for about 30 minutes or until golden brown on top. Let cool before cutting.

Notes

For best results, press the oat mixture firmly into the pan and let the bars cool completely before slicing. Store in an airtight container for freshness.
