Crumble Crust

Rhubarb Filling


  • Pre-heat oven to 350*F.
  • In a bowl, whisk together all of your crust ingredients (except the butter).
  • Add the melted butter and mix until everything is crumbly. Set aside.
  • In another bowl, add all of your filling ingredients except the rhubarb and xanthan gum. Mix until smooth.
  • Add the rhubarb and xanthan gum to the rest of the filling ingredients and mix well until the mixture has coated the rhubarb.
  • Grease an 8x8 inch dish with oil or butter and pour half of your crumble crust mixture over the bottom of the pan (you can even it out but it doesn't have to be pressed in or anything).
  • Next, evenly pour your filling over the crust and then top it with the rest of the crumble mixture.
  • Bake for 25-30min or until crust has browned and filling is bubbly.
  • Serve warm with a dollop of homemade whip cream or low carb vanilla ice cream. Enjoy The Best Keto Rhubarb Crisp! (You can store this covered in the fridge for up to 7 days).

  • I used two sweeteners in this recipe, if you only have one that is completely fine! Just use one for all of the sweetener called for. If you get a chance though, I do recommend the Sukrin Brown Sugar Sweetener because it adds a great flavour to many baked goods recipes!
  • When you add your xanthan gum to your filling, be sure to give it a few good stirs because the more you stir it the more it can thicken the mixture. Alternatively, if you do not have xanthan gum, you can try using a tablespoon of arrowroot starch or just 3 tablespoons total of almond flour.
  • Top this recipe with low carb vanilla ice cream or a dallop of homemade whipped cream if you really want to impress guests!
  • If you are just making this recipe for yourself and would like to lower the calories, you can always bake it with just half the crumble recipe and skip the bottom crust entirely. This will make it out to be 189 calories per serving and just 2.7 NET carbs.
