Blueberry Peach Crumble (Printable)

Blueberries and peaches topped with a buttery oat crumble, baked until golden and bubbling.

# What You’ll Need:

→ Fruit Filling

01 - 2 cups fresh or frozen blueberries
02 - 3 cups sliced fresh or frozen peaches, peeled
03 - 1/3 cup granulated sugar
04 - 2 tablespoons cornstarch
05 - 1 teaspoon lemon juice
06 - 1/2 teaspoon vanilla extract

→ Crumble Topping

07 - 3/4 cup all-purpose flour
08 - 3/4 cup old-fashioned rolled oats
09 - 1/2 cup packed light brown sugar
10 - 1/2 teaspoon ground cinnamon
11 - 1/4 teaspoon salt
12 - 1/2 cup cold unsalted butter, cubed

# Directions:

01 - Preheat the oven to 350°F. Grease a 9-inch square or round baking dish with butter or nonstick spray.
02 - In a large bowl, toss the blueberries, sliced peaches, granulated sugar, cornstarch, lemon juice, and vanilla extract together until the fruit is evenly coated. Spread the mixture in an even layer across the bottom of the prepared baking dish.
03 - In a separate mixing bowl, whisk together the all-purpose flour, rolled oats, packed brown sugar, ground cinnamon, and salt. Add the cold cubed butter and use your fingers or a pastry cutter to cut it into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
04 - Sprinkle the crumble topping evenly over the fruit filling, covering the entire surface.
05 - Place the dish in the center of the oven and bake for 35 to 40 minutes, or until the topping is golden brown and the fruit juices are bubbling around the edges.
06 - Remove from the oven and allow the crumble to cool for 10 to 15 minutes before serving. Serve warm on its own or accompanied by vanilla ice cream or freshly whipped cream.

# Expert Suggestions:

01 -
  • It comes together in fifteen minutes flat, which means you can start it right after dinner and have warm dessert by the time the dishes are done.
  • The crumble topping walks the line between crunchy and tender, and it freezes beautifully if you want to make a double batch for later.
02 -
  • If your peaches are very ripe and juicy, add an extra half tablespoon of cornstarch or the filling will swim across the plate.
  • Cold butter is not a suggestion, it is the law, because warm butter melts into the flour and you end up with a dense slab instead of a craggy crumble.
03 -
  • Toss half the blueberries whole and lightly crush the other half before mixing, which gives you pops of fruit and a thicker sauce at the same time.
  • Adding a handful of chopped pecans or walnuts to the topping introduces a toasty crunch that makes people ask what your secret is.
