A delicious berry crisp that is ready in about an hour.
Place the top oven rack in the center and preheat your oven to 350F.
Place all of your blueberries in a large bowl. Add in the maple syrup, ground cinnamon, ground allspice, and dried rosemary. Toss to combine.
In a separate bowl, combine all of the topping ingredients. Stir until the oats are thoroughly coated.
Pour the blueberry mixture into a 10” cast iron skillet and spread into an even layer. Spread the topping mixture evenly across the top.
Place your cast iron skillet into the oven and bake for 30 minutes or until the top layer is nicely browned. Cover with aluminum foil and bake for another 15-20 minutes or until the blueberry crisp is bubbling.
Remove from oven, set aside to cool for 5-10 minutes, and serve.
A cup of Greek yogurt or vanilla ice cream goes great on the side!
