  • rhubarb, of course! Two pounds of fresh or frozen rhubarb stalks work well. If you use frozen rhubarb, you don’t need to thaw it before baking.

  • brown sugar – Sweeten the toppings. Both light and dark are great!
  • whole grain rolled oats – Bake in the oven for a crisp golden brown color that adds great texture and toasty flavor to your toppings.

how to make rhubarb crispy

This rhubarb crisp recipe couldn’t be easier. Here’s what it looks like:

First prepare the rhubarb. If it has leaves, cut them off and discard. All you need for this recipe is the stem.

Wash well. Next, peel off the tough, stringy outer skin. Cut rhubarb into 1/2-inch pieces.

Toppings sprinkled by hand over the filling in a baking dish

Next, make the rhubarb filling. Mix chopped rhubarb with sugar, cornstarch, orange juice and zest.

Next, make the crumble topping. In a medium bowl, combine almond flour, brown sugar, oats, walnuts, cinnamon and salt. Add the coconut oil (make sure it’s firm!) and knead into the oatmeal mixture by hand until it crumbles. If the mixture feels dry, add water in 1/4 teaspoon increments until it begins to clump with a pinch.

Assemble rhubarb crisps. Transfer rhubarb mixture to an oiled 8-by-8-inch baking dish and spread out in an even layer. Sprinkle oat crumble on top.

And bake! Bake in a 400°F oven for 15 to 25 minutes, until crunchy topping is golden brown and rhubarb is tender.

Let cool for 5 minutes before serving with vanilla ice cream.
