Prep Time: 20 minutes | Cook Time: 40 minutes | Total Time: 60 minutes | Servings: 16 bars
Ingredients
Scale
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar (for the crust)
- 1/2 cup unsalted butter, cold and cubed (keep it cold for best texture)
- 1/4 tsp salt
- 2 cups fresh blueberries (look for plump, firm berries)
- 1/4 cup fresh mint leaves, finely chopped (about 15–20 good leaves)
- 1/2 cup granulated sugar (for the filling)
- 2 tbsp fresh lemon juice (bottled just doesn’t cut it here)
- 2 tbsp cornstarch (this prevents runny filling)
- Powdered sugar for dusting (be generous with this final touch)
Instructions
- Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan with butter—it prevents sticking better than cooking spray and adds flavor.
- In a mixing bowl, combine flour, first 1/2 cup sugar, cold butter cubes, and salt, then mix with pastry cutter or forks until crumbly and press firmly into prepared pan.
- Bake the crust for 15 minutes until lightly golden (not deep brown), then remove and let cool slightly while you prepare the magical filling.
- In a medium saucepan, combine blueberries, chopped mint, second 1/2 cup sugar, lemon juice, and cornstarch—cook over medium heat, stirring occasionally until thickened and jammy (about 5-7 minutes).
- Spread the gorgeous blueberry mint mixture evenly over the warm crust and bake for an additional 20-25 minutes until the top looks set and edges are lightly golden.
- Allow bars to cool completely in the pan before slicing into squares (patience is key here), then dust generously with powdered sugar before serving.

Notes:

- The filling should coat the back of a spoon when properly thickened
