Ingredients
  

Cake Layer

  • 100 g raw cane or date sugar
  • 100 g vegan butter
  • 150 g oat flour*
  • 100 g almonds finely ground
  • 1 tablespoon cornstarch
  • 1 teaspoon baking powder
  • 125 ml plant milk
  • 300 g fresh rhubarb in 1 inch pieces

Vegan Crumble

  • 50 g oat flour
  • 50 g almonds finely ground
  • 50 g vegan butter
  • 50 g sugar cane or dates

Instructions
 

  • Preheat the oven to 350F (180C). With a handmixer, whip the sugar and butter together. Add the rest of the batter ingredients and mix until well combined. Transfer to a 20-cm springform and smooth the top with a spatula.
  • Add the rhubarb and press gently. 
  • With your hands or the mixer, combine the crumble ingredients until the texture ressembles wet sand. Spread evenly over the rhubarb. 
  • Bake in the preheated oven for around 50 minutes. If using wheat flour, the baking time might be shorter. The cake is ready when a toothpick inserted in the middle comes out clean.

Notes

  • To make oat flour, simply process oats in the blender until you obtain a fine powder.
  • This version baked in a 20-cm mould will stay quite juicy. If you prefer drier cakes, use a moul up to 26 cm big, but note that it will be quite thin since this flour mix won't rise as much as wheat or spelt).
