Rhubarb Crisp
Sweet and tart with the perfect amount of crunch! This easy crisp recipe is exactly what you need to use up all the summer rhubarb.

I figured it was time to share a tasty summer dessert recipe. And what better ingredient to use than the vegetable rhubarb.
That’s right! We’re using this summer vegetable to make the best gooey filling with a crispy oatmeal topping.
But, don’t worry. No one will ever know that they’re eating a vegetable for dessert once you’re done.

All you need is some fresh rhubarb, old-fashioned rolled oats, some sugar, and a handful of other ingredients. You can even toss in some ripe strawberries or apples if you like.
Don’t forget to serve it with a scoop of vanilla ice cream!
Storage
Refrigerator: Store leftovers in the refrigerator for 4-5 days.
