Rhubarb Crumble Cake

Rhubarb Crumble Cake

If you have a garden with growing rhubarb, chances are you end up with too much of it. There’s only so much juice you can make! I have bookmarked rhubarb soda and wine recipes and even bought the equipment, but haven’t had time to make any of it yet. So I just wash, chop and freeze my rhubarb in 200 g freezer bags until I know what to do with it. This cake is my go to recipe when I need to free up my freezer in colder months. Very comforting, not too sweet, a bit sour, soft and chewy at the bottom and crunchy on top – perfect.

  • Mmm, denne så god ut!? Den må jeg prøve. Jeg også har fryseren full av monster-rabarbra, fra forrige sommer(!). 2017-avlingen endte dessverre i komposten fordi jeg ikke hadde plass til mer i fryseren. Jeg synes det er vanskelig å finne gode oppskrifter uten et tonn med overraffinert sukker. Vi har brukt denne oppskriften mye: https://www.beritnordstrand.no/rabarbra-crumble/ Viljar(10) elsker den, men Ylva(6) synes den blir litt i sureste laget. Jeg synes den er aldeles deilig, søt, salt og syrlig. Vi spiser den slik den er, uten verken is, krem eller yoghurt. Absolutt å anbefale. Hilse til den kjekke husbonden din!

    • Hei! Takk for oppskriften, jeg skal prove det. Fryseren min er fortsatt full av rabarbra. Jeg prøvd å lage rabarbra lacto-fermented soda, men det var en katastrofe 😀 Jeg kan prøve med vannlig gjær en dag.
      Hilse til familie din også.
