I love how the tart rhubarb pairs so well with the sweeter raspberries in the fruit filling. 

And let’s talk about that crispy, crumbly topping. Man, oh man, is it good! I’ll admit that it’s my favorite part of any type of crisp.

This mixture is the perfect complement when sprinkled on top of the fresh fruit. It’s sweet, crispy, and contains just the right amount of flavor.

Once you dig into this raspberry rhubarb crisp with oats, you’ll be hooked on the sweet fruit, combined with that oh-so delicious crumble. It’s perfect to dig into when it’s right out of the oven, and can even serve as a sweet breakfast.

And don’t forget the ice cream — plop a big ‘ole scoop of vanilla ice cream on top, and this will be your favorite crisp!

Tips for Making Rhubarb Raspberry Crisp

  • I chose to make this rhubarb raspberry crisp in four mini skillets, just because I love mini desserts. But if you don’t have mini skillets handy, a medium skillet or baking dish will work just fine.
  • Make sure to cover the rhubarb filling evenly with the oat topping. This traps the steam and helps soften the rhubarb and raspberries. 
  • If using frozen fruit, don’t thaw it before making the filling. Instead, add a few minutes to the bake time.
