Instructions

1. Preheat oven to 375° and line an 8×8 baking dish with parchment paper and coat with nonstick spray (aff link). Set aside.
2. In a large bowl, combine oats, flour, brown sugar and salt. Add melted butter and vanilla extract, and stir until flour is completely combined and mixture is lumpy.
3. Set aside a little less than 1/2 of the mixture in a small bowl, and press the rest into the bottom of your prepared pan. Set aside.
4. In a medium bowl, combine granulated sugar, lemon juice, lemon zest, and cornstarch. Add blueberries and carefully stir and/or toss the mixture to coat the blueberries.
5. Pour blueberry mixture evenly over crust in prepared baking dish.
6. Top with reserved oatmeal mixture – you’ll still have some of the fruit showing through, and that’s just fine!
7. Bake for 38-42 minutes or until the top is golden brown. Place on a wire rack (aff link) to cool completely (or place in the fridge to cool it more quickly).
8. Use the edges of the parchment paper to lift the bars out of the pan, slice, and serve. Enjoy!
