- 1 quart fresh blueberries (you can always use more!)
- 3/4 cup sugar (or to taste)
- 2 tablespoons cornstarch
- 1 cup water
- 2 -3 tablespoons lemon juice
- 1/2 teaspoon vanilla
- 1 cup all-purpose flour
- 1 cup regular oats
- 3/4 cup brown sugar
- 1 1/2 teaspoons cinnamon
- 1/2 cup butter, melted (no substitutes)
Set oven to 350 degrees F.
Prepare an 11 x 7-inch baking dish
Spread the blueberries in the bottom of the prepared baking pan.
In a small saucepan over medium heat combine the sugar, cornstarch, water and 2-3 Tbsp lemon juice; cook and stir until thick and clear, then add in the vanilla.
Pour over, then gently stir in the cooked mixture with the blueberries.
In a bowl combine the flour with oats, brown sugar and cinnamon.
Add in the melted butter; mix until crumbly.
Sprinkle over the top of blueberries (there will be a couple of empty spots that is okay, there may seem like a lot of crumble but it will settle when baking).
Bake for 30-35 minutes, or until blueberry mixture bubbles and the topping is brown.
Serve with whip cream or ice cream!
