This gluten-free berry crisp is bubbly, jammy mixed berries under a buttery, golden oat crumble. It's easier than pie, works with fresh or frozen berries (no thawing!), and it's naturally nut-free. Make it a day ahead and bake it right before serving with a big scoop of vanilla ice cream.
Preheat oven to 400°F and spray a 2 quart baking dish with non stick spray and set aside.
In a large mixing bowl, mix together the berries, flour, brown sugar, cinnamon, vanilla, and salt. Add mixture to the prepared baking dish and set aside.
7 cups berries, 1/4 cup light brown sugar, 1 teaspoon cinnamon, 1 teaspoon vanilla extract, ½ teaspoon kosher salt, 1/4 cup gluten-free flour
Whisk together the gluten-free flour, brown sugar, and cinnamon. Use a pastry blender or fork to cut the cold butter into the mixture until it becomes crumbly. Stir in the gluten-free oats. Cover the berry mixture with the oat topping.
3/4 cup gluten-free flour, 1 cup old fashioned rolled oats, 3/4 cup light brown sugar, 1 teaspoon cinnamon, 1/2 cup unsalted butter
Bake in the pre-heated oven for 40-45 minutes or until the crumble topping is golden brown and the edges are bubbling. Begin checking the crisp at 35 minutes and cover with foil if needed to avoid over-browning. Allow to cool slightly and serve warm with whipped cream or ice cream.
Notes
Frozen Berries: no need to thaw. Add them straight to the dish and bake a few extra minutes if needed.Gluten-free flour: use a 1:1 blend that includes xanthan gum. I used Bob's Red Mill 1:1.Oats: use certified gluten-free oats if you're baking for someone with celiac disease.Dairy-free/vegan: swap the butter for coconut oil.Sugar: coconut sugar can replace the brown sugar.Make ahead: assemble up to 24 hours ahead and refrigerate until ready to bake.Storage: refrigerate leftovers for up to 5 days or freeze for up to 3 months. Reheat at 350°F for 30 to 40 minutes, or until warmed through.
