  • 9x13 baking dish, 3-qt. capacity


For the filling:

  • 3 cups blueberries
  • 3 cups blackberries
  • 3 cups raspberries
  • 1/3 cup white granulated sugar
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/3 cup all-purpose flour
  • 1 lemon grated zest only

For the topping:

  • 2 tablespoons white granulated sugar
  • 1/3 cup light brown sugar
  • 1 cup all-purpose flour
  • 1/2 cup old fashioned rolled oats*
  • 1 teaspoon ground cinnamon
  • 1 pinch kosher salt
  • 1/2 cup (1 stick) Land O Lakes® Unsalted Butter cold and cut into pieces

To serve:

  • Vanilla ice cream


  • Preheat your oven to 375 degrees.
  • Using a large mixing bowl, pour in the blueberries,blackberries and raspberries. Sprinkle the sugar, cinnamon, nutmeg, flour and lemon zest over the top and gently mix to combine. Pour into your baking dish and set aside.
  • Prepare the crumb topping:
    Using another large mixing bowl, combine the sugars, flour, rolled oats, cinnamon and salt. Add in the cold Land O Lakes® Unsalted Butter pieces and, using a pastry blender or your fingers, cut the butter into the dry mixture until you have a coarse crumb mixture. If using your fingers, rub in the butter throughout the mixture.
  • Scatter the crumb topping evenly, in one layer, over the berry mixture. Bake, uncovered, until golden brown and crisp and bubbling, for about 40 minutes. Remove from the oven and let sit for at least 10 to 15 minutes (or up to one hour for best results) before serving. Serve with ice cream if desired and enjoy!
