How to make GF Blueberry Crisp
Preheat the oven to 350º F (180°C).
Place gluten-free rolled oats, gluten-free all-purpose flour, brown sugar, and cinnamon in a food processor. Add the cooled diced butter and process. Or place them in a medium bowl and toss them with your fingertips to combine. Let the crumble rest in the refrigerator.
In a large bowl, place the blueberries, lemon juice, cornstarch, and sugar and mix gently.
Place the blueberry mixture into the desired molds. This recipe uses individual ramekins, but you can also use a baking dish, an 8” square pan, a 9-in. pie plate, or similar.



Let rest for 10 minutes, and sprinkle the oat mixture over the blueberries. End it with the chopped toasted almonds.
Bake for about 40 minutes, until the topping is golden brown and the blueberries are tender and bubbling.
Serve warm with whipped cream or a scoop of ice cream if desired.
