Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and gather your baking supplies.
- In a large mixing bowl, combine flour, brown sugar, and softened butter, mixing until coarse crumbs form. Press into the greased baking dish and bake for 10 minutes.
- In another bowl, mix blueberries, lemon zest, and sour cream. Pour this over the crust once baked.
- Mix remaining brown sugar, flour, and rolled oats together for the topping and sprinkle over the blueberry layer.
- Bake for 45-60 minutes until the topping is golden and the filling is bubbling.
- Allow the bars to cool in the pan for at least 30 minutes before slicing.

Notes
Use fresh or properly thawed blueberries for the best flavor. Allow cooling time for cleaner slices.
