Ingredients
Here’s what you’ll need to make this keto rhubarb crumble:
- 4 cups fresh rhubarb, chopped into 1-inch pieces
- 1/4 cup granulated erythritol or monk fruit sweetener
- 1 tsp vanilla powder
- 1 cup almond flour
- 1/4 cup coconut flour
- 1/2 cup unsalted butter, chilled and cubed
- 1/4 cup chopped pecans or walnuts (optional)
- 1/2 tsp cinnamon
- Pinch of salt

Instructions
Follow these simple steps to make the perfect keto rhubarb crumble:
- Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish with butter or coconut oil.
- In a medium bowl, toss the chopped rhubarb with 2 tablespoons of the sweetener and vanilla powder. Spread the mixture evenly in the prepared baking dish.
- In another bowl, combine almond flour, coconut flour, cinnamon, salt, and the remaining sweetener. Add the chilled butter cubes and use your fingers or a pastry cutter to work the butter into the flour mixture until it resembles coarse crumbs.
- Sprinkle the crumble mixture over the rhubarb, covering it completely. If using, sprinkle chopped nuts on top for extra crunch.
- Bake for 30-35 minutes, or until the topping is golden brown and the rhubarb is bubbling.
- Let the crumble cool for 10 minutes before serving. Enjoy warm with a dollop of whipped cream or keto ice cream.
Tips and Tricks
For the best results, keep these tips in mind:
- If rhubarb is out of season, you can use frozen rhubarb—just thaw and drain it well before using.
- For extra flavor, add a pinch of ginger or nutmeg to the crumble topping.
- If you prefer a softer texture, cover the crumble with foil for the first 20 minutes of baking.
- Store leftovers in an airtight container in the fridge for up to 3 days.
