A tender traditional Norwegian rhubarb cake with a delicate, crumbly crust and a soft, juicy rhubarb filling, perfect for spring and early summer gatherings.
If rhubarb is very juicy, drain excess liquid before mixing to avoid soggy crust. Keep butter chilled for crumbly crust texture. Let rhubarb sit with sugar and lemon zest to mellow tartness. Cool cake fully before slicing to thicken filling. Can substitute gluten-free flour blend with xanthan gum for gluten-free version. Coconut oil can replace butter for vegan version, adjusting sugar accordingly.
