This easy Blackberry Crisp is warm and gooey with a crispy crunchy oat topping. It's best served warm and topped with vanilla ice cream.
Preheat oven to 350 degrees. Add berries, lemon juice and sugar to a medium bowl and toss to combine.
Add both flours, oats, brown sugar, and butter to a food processor. Process until the mixture is crumbly.
Add the berries to an oven safe pan or a 12 inch cast iron skillet. Top with crumb mixture.
Bake for 30 minutes or until the top is golden brown and the berries are soft and bubbly.
Serve immediately with whipped cream or ice cream, if desired.
