  • 2 bags (12-15 oz each) frozen mixed berries
  • 1 box (15.25 oz) french vanilla cake mix
  • ½ cup old-fashioned oats
  • ½ cup chopped walnuts
  • ½ cup (1 stick) salted butter melted


  • Heat oven to 350° and spray a 9x13 baking dish with cooking spray.
  • Spread out frozen berries in the bottom of the dish (DO NOT thaw the berries beforehand).
  • In a mixing bowl, combine the cake mix (DO NOT prepare beforehand), oats, walnuts, and melted butter. Stir together until thick crumbles form. Sprinkle evenly over the frozen berries.
  • Cook for 50-55 minutes. Crisp topping will be a golden brown and the berries will be bubbling.
  • Serve warm with a scoop of vanilla ice cream.



Oats : You can use old-fashioned oats OR quick oats in this recipe. Old-fashioned oats provide more texture because of their size, but either will work just fine. 
Frozen Berries : For some reason all the brands make the frozen berries in different sizes. Only different by an ounce or so. Make sure you get two bags of frozen mixed berries between 12 oz - 16 oz each. 
Cake Mix : The French vanilla is the best cake mix to use in this dump cake. If you just cannot find it then a yellow cake mix can be used but try to get the vanilla cake mix because it really does taste the best in this recipe. 
Nuts : If you don't like walnuts then use a different nut. Almonds and pecans are both great choices. I actually use closer to ¾ cup chopped walnuts in this recipe because I love the nuts in the crisp topping. Adds so much balance and texture to the dish. 
Nutrition & Serving Size : I think a small amount of this dessert goes a long way, especially once it's topped with ice cream. I can serve 10 people with this dump cake recipe with each serving being topped with a scoop of ice cream. The nutrition information is just for one serving of the dump cake and does not include ice cream on top.
