Triple Berry Crisp is an easy dessert recipe bursting with blueberries, raspberries and blackberries, then finished with a sweet oat crumble. Serve it piping hot with a scoop of ice cream or enjoy it the next day for breakfast. Gluten-free, dairy-free options!


  • 1 pint fresh Blueberries
  • 12 ounces fresh Raspberries
  • 6 ounces fresh Blackberries
  • 3 tablespoons granulated sugar
  • 2 tablespoons tapioca flour
  • 1 cup rolled oats
  • 1/2 cup flour (see notes)
  • 1/3 cup brown sugar
  • 1/4 teaspoon ground cinnamon
  • 1/4 teaspoon fine sea salt
  • 6 tablespoons unsalted butter


  1. Preheat oven to 375ºF and grease a 9×9 pan or similar size (1 quart casserole dish, etc.)
  2. Prepare berries: In a large bowl combine berries with granulated sugar and tapioca flour; be very gentle with raspberries as to not smash them; set aside.
  3. Make crisp topping: In a medium bowl add rolled oats, flour, brown sugar, cinnamon and salt; combine then add melted butter and stir well until combined.
  4. Add to dish: Transfer berry mixture to greased pan, evenly layering berries and spreading them out evenly throughout the dish. Add on oat crisp topping, pressing together some clumps, and evenly covering the berries.
  5. Bake: Bake berry crisp for about 40 minutes, uncovered, until topping is golden brown and and filling is bubbly and juicy. 
  6. Serve: Allow crisp to cool slightly before serving. My favorite topping is ice cream for a dessert, but yogurt is delicious the next morning as leftovers!


STORAGE – Keep it on the kitchen counter for 1 day (this keeps the oat topping crisp) or wrap it tightly in plastic wrap to store in the fridge for up to 5 days.

REHEATING – Remove the baking dish from the fridge while the oven preheats to 350ºF. Remove the plastic wrap and tent with foil. Reheat in the oven for 20 minutes. OR, scoop out your desired portion into a microwave-safe bowl and microwave on high in 30-second increments.
