1cupflour (or oat flour for gluten-free, see notes)
1cupold-fashioned whole rolled oats
¼teaspoonsalt
½teaspooncinnamon
½cupchopped pecans (optional)
⅓cupmelted butter (or coconut oil for dairy-free)
½cuppure maple syrup
Instructions
Preheat the oven to 350F.
Add the blueberries, raspberries, blackberries, lemon juice, cornstarch, and ¼ cup maple syrup to a 9x9 or similar oven-proof baking dish.
In a medium bowl combine the oat flour, rolled oats, salt, cinnamon, and pecans (if using).
Pour in the melted coconut oil (or butter) and ½ cup maple syrup. Stir together until well combined. If the mixture seems a little wet let it sit for a minute or two to thicken up.
Using your hands or a large spoon, layer the oat mixture over the berry mixture.
Bake, uncovered until the berries are bubbling and the topping is browned, about 45-50 minutes.
You may want to place a sheet pan lined with foil under the baking dish to catch spills in case the berries bubble over the side of the dish while baking.
Let cool at least 15 minutes for the berry layer to thicken. Serve hot or at room temperature.
Notes
Flour: Use oat flour here to keep this berry crisp gluten-free, or regular all-purpose flour if you prefer.
Gluten-Free: For gluten-free, be sure to buy oats, oat flour and cornstarch specifically labeled gluten-free.
Dairy-Free: I use melted coconut oil when I want to keep this recipe dairy-free, and butter otherwise.
