Ingredients

Scale

Blueberry Filling

  • 2 1/2 cups fresh blueberries (rinsed off)
  • 2 tablespoons fresh lemon juice
  • 2 teaspoons corn starch
  • 1/4 cup sugar

Oat Crust and Crumble

  • 6 tablespoons unsalted butter (melted)
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups old fashioned oats (not instant)
  • 1/2 cup honey
  • 1/4 cup brown sugar (packed)
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt


Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) to prepare for baking the bars.
  2. Prepare the pan: Line the bottom of an 8×8 inch baking pan with parchment paper, leaving some overhang for easy removal of the bars. Set aside.
  3. Make the crust and crumble mixture: In a large bowl, combine the flour, oats, honey, brown sugar, ground cinnamon, and a pinch of salt. Stir until all dry ingredients are evenly mixed.
  4. Add wet ingredients: Pour in the melted butter and vanilla extract, mixing until the mixture begins to come together.
  5. Knead the mixture: Use your hands to knead the mixture gently until it forms a crumbly dough-like consistency. It should be slightly dry and crumbly.
  6. Set aside crumble topping: Reserve 1 cup of this oat mixture for the crumble topping; set it aside.
  7. Press crust into pan: Take the remaining oat mixture and evenly press it into the bottom of the prepared baking pan to form the crust.
  8. Prepare blueberry filling: In a medium bowl, mix the fresh blueberries, lemon juice, sugar, and corn starch. Stir gently until the blueberries are well coated.
  9. Layer blueberry filling: Spread the blueberry mixture evenly over the oat crust in the baking pan.
  10. Add crumble topping: Sprinkle the reserved 1 cup of oat mixture evenly over the blueberry layer, creating the crumble topping.
  11. Bake the bars: Place the pan in the oven and bake at 350°F for 45 minutes. Check occasionally to ensure the bars do not burn and the topping becomes golden brown.
  12. Cool the bars: Once baked, remove the bars from the oven and let them cool in the pan for about 10 minutes to set.
  13. Cut and serve: Use the parchment paper overhang to lift the bars out of the pan, cut into 8 equal pieces, and enjoy your delicious breakfast bars.

Notes

  • Ensure the blueberries are well coated with the lemon juice and corn starch to prevent the filling from becoming too runny.
  • Use old fashioned oats for better texture; instant oats may make the bars too soft.
  • Allow bars to cool before cutting to help maintain their shape.
  • These bars can be stored in an airtight container at room temperature for up to 3 days, or refrigerated for up to a week.
  • Optional: add chopped nuts like walnuts or pecans to the oat mixture for extra crunch.
  • To make these gluten-free, substitute the all-purpose flour with a gluten-free flour blend.
