These rhubarb custard bars feature a buttery shortbread crust, silky custard, and tangy rhubarb for a cozy, balanced dessert perfect for spring and summer.
If crust edges brown too quickly, tent with foil halfway through baking. Chilling bars in freezer for 30 minutes after baking speeds custard setting. Use softened butter (not melted) for best crust texture. Macerate rhubarb to reduce moisture and prevent soggy crust. Avoid overbaking custard to keep creamy texture. Bars taste better after chilling overnight.
