Ingredients

For the rhubarb filling

  • 6 cups chopped rhubarb (1/2 inch pieces)
  • 1/4 cup white sugar
  • 2 tsp vanilla extract
  • 1 tbsp cornstarch
  • 1 tbsp orange juice

For the crisp topping

  • 1 1/2 cups gluten free rolled oats
  • 3 tbsp brown sugar
  • 1/2 cup chopped walnuts
  • 3/4 tsp ground cinnamon
  • 1/4 tsp salt
  • 1/2 cup almond flour
  • 1/4 cup butter, melted
  • 1/4 cup almond butter

Instructions

  • Preheat the oven to 350F and grease an 9x9 baking dish or 10 inch skillet with coconut oil, nonstick cooking spray or butter.
  • In a large bowl mix together chopped rhubarb along with the sugar, vanilla extract, cornstarch and orange juice.
  • In another bowl make the topping by mixing together the rolled oats, brown sugar, chopped walnuts, cinnamon, salt and almond flour until combined. Add the melted butter and almond butter and use a fork to mix well, it should form small clumps.
  • Pour the rhubarb mixture and all of the juices into the greased baking dish. Then sprinkle the crisp topping evenly over the rhubarb mixture and pat it down gently.
  • Bake for 45-55 minutes, until the rhubarb filling is very bubbly and the fruits are fork tender. The top should be turning golden brown.
  • Let rest 10-15 minutes before serving. Top with ice cream, coconut or greek yogurt if desired!

Notes

  • In a pinch you can use frozen rhubarb instead of fresh in this recipe.  Measure the rhubarb frozen first and then thaw completely. Drain the rhubarb using a strainer (do not squeeze the rhubarb) and then toss with the other filling ingredients. 
  • If you're not gluten-free, simply use regular rolled oats for the topping.
  • You can substitute the melted butter with melted coconut oil if desired.
  • If you're looking to make this crisp recipe more refined sugar free try using coconut sugar as a substitute for brown sugar and monk fruit or maple syrup as a substitute for the white sugar.
