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!

Rhubarb Filling

Instructions
 

  • Preheat the oven to 400°F, and lightly grease an 8-inch round, 8 x 8-inch baking dish, or 2-quart dish.

For the Crumb Topping

  • In a medium bowl, use a pastry cutter or your hands to combine the topping ingredients until well mixed.
    1 cup old-fashioned rolled oats
    6 tablespoons unsalted butter
    ½ cup all-purpose flour
    ½ cup brown sugar
    ¼ cup granulated sugar
    ½ teaspoon ground cinnamon
    ½ teaspoon salt
  • Transfer the crumb topping to the refrigerator while you prepare the filling.

For the Rhubarb Filling

  • Add the rhubarb, brown sugar, ¼ cup of water, vanilla and cinnamon to a medium saucepan. Bring to a simmer over medium heat, and cook for about 5 minutes.
    6 cups rhubarb
    ¾ cup light brown sugar
    2 teaspoons pure vanilla extract
    1 teaspoon ground cinnamon
  • While the rhubarb mixture cooks, make a slurry by mixing the remaining ¼ cup cold water and 2 tablespoons of cornstarch until smooth. Add the slurry, and stir until the mixture beings to thicken, about 2 to 3 minutes.
    2 tablespoons cornstarch
  • Add the rhubarb mixture to the prepared baking dish then sprinkle the crumb topping over the top.
  • Bake for 30 to 35 minutes or until the top turns a light golden color and the center jiggles slightly. The filling will be bubbly around the edges.
  • Allow the crisp to rest for 5-10 minutes before serving. Serve warm with vanilla ice cream!
