Juicy peaches, sweet blueberries, and a cinnamon-ginger oat crumble… this blueberry peach crisp tastes like summer in a pan. It’s simple (no dough to roll!), uses pantry staples, and bakes up bubbly and golden for the coziest dessert.
Grease an 8×8-inch baking dish (or a 9-inch pie dish). Preheat oven to 350 degrees F.
In a large bowl (or directly into the prepared dish) , gently toss peaches, blueberries, tapioca flour, cinnamon, ginger, maple syrup, vanilla, and salt until the fruit is evenly coated. Transfer to the greased baking dish (or 10-inch cast iron skillet) and spread into an even layer.
In a medium bowl, stir oats, almond flour, cane sugar, cinnamon, melted butter, and salt until clumpy and evenly moistened. Sprinkle the crumble evenly over the fruit—no need to press it down.
Bake 30 minutes, then loosely cover with foil and bake 20–30 minutes more, until the topping is golden and the peach filling bubbles around the edges. Let it rest for 10–15 minutes to set the juices. Serve warm with ice cream, whipped cream, or Greek yogurt!
