  • 2 Mixing bowls
  • 1 Pie dish (glass works best)


For the crumble

  • 1 cup Walnuts (finely diced)
  • 1/2 cup Coconut flour
  • 1/4 cup Flaxseed meal
  • 1/4 cup Stevia
  • 6 tbsp Plant butter (Flora is best)
  • 1/4 tsp Sea salt

For the filling

  • 1 cup Strawberries (finely diced)
  • 1 cup Rhubarb (finely diced)
  • 1 tbsp Lemon juice
  • 1-2 tsp Stevia
  • 1/2 tsp Xanthan gum


  • Preheat oven to 340 F (170 C)
  • 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.
  • In another bowl, combine walnuts, coconut flour, flaxseed meal, 1/4 cup stevia, sea salt and toss together so it mixes evenly
  • Add plant butter and combine until the whole mix is crumbly
  • Set 1/2 cup of the crumble aside and the other 1 tsp sweetener to it
  • 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
  • Pour the fruit mixture over the crust and spread evenly
  • Finally, sprinkle the remaining 1/2 cup of crumble over the pie
  • 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)
  • 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. Enjoy!
