Make a satisfying, low-carb fruit crisp using tart rhubarb and a buttery, sugar-free almond flour topping. This recipe is perfect for a diabetic friendly rhubarb dessert.

Ingredients

Scale
  • 4 cups fresh or frozen rhubarb, chopped
  • 1/2 cup erythritol or monk fruit blend (or allulose)
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon lemon juice
  • 1/4 cup water
  • 1 1/2 cups blanched almond flour
  • 1/2 cup erythritol or monk fruit blend (for topping)
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 cup cold unsalted butter, cut into small pieces
  • 1/4 cup chopped pecans or walnuts (optional, for extra crunch)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking dish.
  2. Prepare the filling: In a medium bowl, combine the chopped rhubarb, 1/2 cup sweetener, vanilla extract, lemon juice, and water. Toss gently to coat. Pour the mixture into the prepared baking dish.
  3. Prepare the keto crisp topping: In a separate bowl, whisk together the almond flour, 1/2 cup sweetener, cinnamon, and nutmeg.
  4. Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. If using nuts, mix them in now.
  5. Sprinkle the topping evenly over the rhubarb filling in the baking dish.
  6. Bake for 35 to 45 minutes, or until the topping is golden brown and the rhubarb filling is bubbly.
  7. Let the crisp cool for at least 15 minutes before serving. This allows the filling to set slightly.

Notes

  • For a berry variation, substitute 1 cup of the rhubarb with low-carb berries like raspberries or strawberries.
  • If you prefer a different sweetener, substitute erythritol 1:1 with allulose or your preferred keto granular sweetener.
  • To make this recipe gluten free, confirm your almond flour is certified gluten free.
  • Serve warm with a scoop of keto vanilla ice cream for a comforting low carb warm dessert idea.
