Ingredients
6 cups frozen mixed berries (strawberries, blueberries, raspberries)
3 tablespoons cornstarch
1 tablespoon freshly squeezed lime juice
3 tablespoons granulated sugar
8 tablespoons (1 stick) unsalted butter (cold, cut into 1-inch pieces)
¼ cup + 2 tablespoons granulated sugar
¼ cup light brown sugar (packed)
¼ teaspoon kosher salt
1 cup gluten-free quick-cooking oats
½ cup gluten-free old-fashioned oats
Instructions
Preheat oven to 350°F (175°C). Grease an 8×8 inch baking pan.
In a large bowl, combine frozen berries, cornstarch, lime juice, and 3 tablespoons sugar. Stir until fully coated.
Pour berry mixture into prepared baking pan and spread evenly.
In another bowl, mix granulated and brown sugars, kosher salt, and both oat types. Add cold butter and cut in until mixture resembles coarse crumbs.
Sprinkle oat crumble over the berry mixture, covering the surface completely.
Bake for 35-40 minutes or until filling is bubbly and topping is golden brown. Cool for 10 minutes before serving.
Notes
Use fresh berries by increasing to 8 cups and patting dry before adding cornstarch.
Store leftovers in an airtight container at room temperature for 1 day or refrigerated for up to 3 days.
Top with Greek yogurt or whipped coconut cream for a non-dairy option.
Ensure all oats are certified gluten-free to avoid cross-contamination.
