Slow Cooker Triple Berry Crisp

Yield: 12 servings
Prep Time:
10 mins
Triple berry crisp, made easy in the slow cooker! Recipe works with fresh or frozen berries, is healthy compared to most, and can be made gluten free.


  • 1 1/4 cups old-fashioned rolled oats certified gluten free if needed; do not use quick, instant, or steel-cut oats as they will not cook properly
  • 3/4 cup  white whole wheat flour  — to make gluten free, swap a 1:1 baking blend or 1/2 cup almond flour/meal mixed with 1/4 cup additional oats
  • 1/2 cup sliced almonds — or swap chopped walnuts, pecans, or simply omit
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon kosher salt
  • 6 tablespoons unsalted butter — melted and cooled to room temperature (to make vegan or dairy free, swap vegan butter or melted coconut oil)
  • 1/3 cup pure maple syrup — or honey, I use maple syrup
  • 5 cups mixed berries — fresh or frozen (I used a blend of blueberries, raspberries, and blackberries)
  • 1 tablespoon freshly squeezed lemon juice
  • 2 teaspoons pure vanilla extract
  • 1/2 to 1 tablespoon cornstarch
  • Optional for serving: vanilla ice cream — or frozen yogurt, whipped cream, or Greek yogurt


  1. Coat a 5- to 6-quart slow cooker with nonstick spray or line with a nonstick liner. In a large bowl, combine the oats, whole wheat flour, almonds (if using), cinnamon, and salt. Pour the melted butter and maple syrup over the top, then stir to evenly moisten.
  2. If using frozen berries, rinse them so that any large ice crystals are removed (the berries do not need to be completely thawed). Place in a large bowl, then stir together with the lemon juice, vanilla, and 1/2 tablespoon cornstarch (if using fresh berries) or 1 tablespoon cornstarch (if using frozen). Transfer to the prepared slow cooker, then sprinkle the oat mixture evenly over the top. Lightly coat the top of the crisp with nonstick spray.
  3. Lay a sheet of paper towel or kitchen towel over the top of the slow cooker so that it overhangs the sides and will stay in place once the slow cooker is covered. (This absorbs moisture and helps the top to crisp). Cover and cook for 1 to 2 hours on high or 2 to 3 hours on low, until the fruit is bubbly and the top is browned. If your berries are still frozen, the cooking time may be longer. Serve warm, topped with vanilla ice cream, Greek yogurt, or whipped cream as desired.
