- Granulated sugar – Sweetens the blueberries, balancing their natural tartness and enhancing their flavor.

- Rolled oats – Add a hearty, chewy texture and nutty flavor to the topping, making it more substantial and delicious.

- Butter – Binds the topping ingredients together and helps create a crispy, golden-brown crust that is both rich and flavorful.
How to make blueberry crisp:
(The full written and printable recipe is further below.)

- Place the blueberries in a greased 8″ square or round baking dish.
- Add the sugar, flour, and cinnamon. Gently mix to coat the blueberries.
- In a medium bowl, mix together the flour, rolled oats, and brown sugar. Add in the melted butter and stir until everything is moistened.
- Sprinkle the oat topping evenly over the blueberries. Bake at 350F for about 30 minutes or until the filling is bubbling and the topping is golden brown.
Variations:
- Mixed berry crisp – Substitute half of the blueberries with other berries like raspberries, blackberries, or strawberries for a mixed berry twist.
- Lemon blueberry crisp – Omit the cinnamon and add the zest of a lemon to the filling for a tangy, citrus-infused variation.
- Nutty topping – Add 1/2 cup of chopped nuts such as pecans, almonds, or walnuts to the topping mixture for extra crunch and a nutty flavor.
- Coconut twist – Add shredded coconut to the topping for a tropical flavor.
- Honey or maple syrup – Replace the granulated sugar in the filling with honey or maple syrup for a different type of sweetness and flavor depth.
How to serve:
Serve warm from the oven, topped with a generous scoop of vanilla ice cream or a dollop of freshly whipped cream. For an added touch, drizzle with a bit of honey or maple syrup. This dessert is equally delicious served chilled, making it a versatile treat that can be enjoyed in any season.

Great and very easy recipe! I made the mistake of using only one pint of blueberries because that’s all I bought. Next time I will definitely use two and maybe more. 😉
Thank you for this amazing recipe!
