Blackberry Peach Crisp

This blackberry peach crisp recipe is one of my favorite desserts to make during the summer. It highlights delicious in-season fruit and it's not too heavy--perfect for especially warm days. I love to serve it warm topped with scoops of vanilla ice cream.

Equipment

  • mixing bowl set
  • 2-quart baking dish
  • dry measuring cups
  • measuring spoons

Ingredients

For the brown sugar-oatmeal topping:

  • 1 cup old-fashioned oats
  • 1 cup all-purpose flour
  • 1 cup firmly packed brown sugar
  • 1 teaspoon ground cinnamon
  • ¾ cup Duke's mayonnaise

For the blackberry peach crisp:

  • 3 large peaches, peeled and sliced
  • 3 cups blackberries
  • 1 tablespoon fresh lemon juice
  • 2 tablespoon granulated sugar
  • 2 tablespoon cornstarch
  • Vanilla ice cream (optional)

Instructions

  • Preheat the oven to 350°F. Make the brown sugar-oatmeal topping: Combine oats, flour, brown sugar, cinnamon, and mayonnaise in a medium bowl. Squeeze the mixture to create large clumps. Set aside.
  • Combine peaches, blackberries, lemon, sugar, and cornstarch in a large bowl. Transfer the peach filling to a large ovenproof skillet or 2-quart baking dish. Top evenly with the brown sugar-oatmeal topping.
  • Bake the crisp at 350°F for 35 to 40 minutes, until the topping is golden brown and the fruit mixture is bubbly. Remove from the oven and serve warm with a scoop of ice cream, if desired.
