  • Author: Jessie

Crunchy, gooey, sweet, tart, nutty, and fruity, this crisp couldn’t be a better summer dessert when piled high with some vanilla ice cream or whipped cream!


  • 1 cup white sugar
  • 3 tablespoons all purpose flour
  • 3 cups fresh or frozen mixed berries (I used blueberries, strawberries, and blackberries)
  • 3 cups diced rhubarb
  • 1 ½ cups all purpose flour
  • 1 cup packed brown sugar (affiliate)
  • 1 cup butter (affiliate), softened
  • 1 cup rolled oats
  • 1/2 teaspoon cinnamon (affiliate)


  1. Preheat oven to 375 degrees.
  2. Combine sugar, 3 tablespoons flour, berries, and rhubarb in a large mixing bowl. Pour the mixture into a 9×13 inch baking dish.
  3. Mix together 1 ½ cups flour, brown sugar, softened butter, oats, and cinnamon until crumbles start to form. Sprinkle on top of triple berry rhubarb mixture.
  4. Bake for 45 minutes until lightly browned. Let cool slightly then serve with ice cream or whipped cream.
