These tangy rhubarb custard bars feature a buttery shortbread crust with a smooth, tangy rhubarb custard filling, perfect for spring and summer treats.
Use softened butter, not melted, for the crust to ensure proper crumbly texture. Puree rhubarb for smooth custard but keep some texture. Bake crust first to prevent sogginess. Cool bars completely before slicing. For dairy-free, substitute butter with coconut oil and heavy cream with coconut cream; replace eggs with flax or chia eggs.
