Ingredients

For the filling:
- 4 cups fresh or frozen blueberries
- 1/3 cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
- 1/2 teaspoon vanilla extract
For the crisp topping:
- 3/4 cup old-fashioned rolled oats

Tips for Success
- Use cold butter for the topping — this helps create a perfectly crumbly and crisp texture.
- Don’t overmix the topping — keeping some chunks of butter intact gives you that irresistible crunch.
- Frozen berries work great — just add 1 extra teaspoon of cornstarch to account for the extra moisture.
- Let it rest before serving — the filling thickens as it cools, making for cleaner servings.
Common Questions
