Notes on Ingredients

- Blackberries: Feel free to use fresh or frozen blackberries to make blackberry crisp. And while this recipe calls for blackberries, feel free to use any combination of berries you like.
- Lemon Juice: A small amount of fresh lemon juice will help to brighten up the flavors of the blackberry filling. It is a key ingredient you don't want to overlook for the best flavor.
- Cornstarch: Cornstarch helps to thicken up the juices the berries release as they bake. If you have a corn allergy, you can substitute arrowroot powder for cornstarch.
- Sugar: This recipe calls for both granulated sugar and brown sugar. The granulated sugar is the best choice for the berry mixture, as it dissolves easily into the berry juices when baked and the brown sugar adds rich undertones to the crisp topping.
- Butter: Be sure to use unsalted butter that is at room temperature for best results.
- Oats: Use ether rolled or quick-cooking oats, not steel-cut oats.
How to Make Blackberry Crisp
- For the blackberries filling, toss together the berries, sugar, lemon juice, and cornstarch together until the berries are evenly coated with the cornstarch and sugar. It is okay if the cornstarch does not dissolve. It will when baked!
- Place the berry mixture into a buttered baking dish.

- In a separate medium mixing bowl, mix together the flour, oats, cinnamon, brown sugar, and butter together until the mixture is crumbly and evenly combined. I find it is best to do this with your hands.

- Spread the crumble evenly over the berries.

- Bake for 35-40 minutes or until the berries are soft and the juices are bubbly and the crisp topping is golden.
- Serve warm. I highly recommend serving this crisp with a scoop of vanilla ice cream or whipped cream as desired.

Recipe Modifications
- Dairy-Free Blackberry Crisp: I have made this blackberry crisp using vegan Earth Balance butter sticks in place of the butter with fabulous results. My family didn't even suspect a difference.
- Gluten-Free Blackberry Crisp: Be sure your oats are certified gluten-free and replace the all-purpose flour with a 1:1 gluten-free flour blend. The results are superb.
- Using Frozen Berries: Do not defrost the berries, simply mix the frozen berries with the cornstarch, lemon juice, and sugar and proceed with the recipe as directed.
