I hope you enjoy this Strawberry Rhubarb Crumble, my whole household and family loved it!



For the filling:

  • 1 cup, finely diced strawberries
  • 1 cup, finely diced rhubarb
  • 1 tbsp lemon juice
  • 12 tsp Steviva Blend (or your favorite stevia/erythritol baking blend) I used 1 tsp, but some people love a really sweet pie, in which case, use 2.
  • 1/2 tsp xanthan gum

For the crumble:

  • 1 cup, finely diced walnuts
  • 1/2 cup coconut flour
  • 1/4 cup flaxseed meal
  • 1/4 cup + 1 tsp Steviva Blend (or your favorite stevia/erythritol baking blend)
  • 6 tbsp, melted unsalted butter
  • 1/4 tsp sea salt


  1. Preheat oven to 350 degrees F
  2. In a bowl, combine filling ingredients. Xanthan gum should be lightly sprinkled while mixing so that it’s evenly spread and doesn’t clump. Set bowl aside.
  3. In another bowl, combine walnuts, coconut flour, flaxseed meal, 1/4 cup sweetener, sea salt and toss together so it mixes evenly.
  4. Add butter and combine until the whole mix is crumbly.
  5. Set 1/2 cup of the crumble aside and the final another 1 tsp sweetener to it.
  6. Grease a 9″ glass pie dish with butter, then press down the bowl of crumble. Use your hands to press it flat into the bottom.
  7. Pour the fruit mixture over the crust and spread evenly.
  8. Finally, sprinkle the remaining 1/2 cup of crumble over the pie.
  9. Bake for about 20 minutes covered with tinfoil, then a final 10-20 minutes until crumble is browned (this will prevent burning the crumble because this dish needs a little time to cook).
  10. Once finished, let cool completely in the refrigerator (at least a few hours to set so it can be sliced and held like a pie), then serve.
  11. Enjoy!


Nuts brown quickly, so if you don’t cover the pie while baking, the crumble will brown and begin to burn. The pie needs some time to cook due to the rhubarb, so you don’t want them to brown or burn too early.
