tips to make Rhubarb Custard Bars

  • Chop rhubarb into even pieces so it cooks evenly.
  • Press the crust firmly to make a solid base.
  • Let the bars cool fully before cutting to get clean slices.
  • If rhubarb is very tart, add 1-2 tablespoons more sugar to the filling.
  • Use room-temperature eggs for a smoother custard.

variation (if any)

  • Add 1/2 cup chopped strawberries for a strawberry-rhubarb twist.
  • Sprinkle 1/4 cup oats into the crust mix for a nuttier texture.
  • Swap cinnamon for a pinch of nutmeg or ginger for a different spice note.

FAQs

Q: Can I use frozen rhubarb?
A: Yes. Thaw and drain excess liquid before mixing so the filling is not too watery.

Q: Can I make these in a smaller pan?
A: You can use an 8×8 pan, but the bars will be thicker. Bake a few minutes longer and watch for a set center.

Q: Do I need to peel rhubarb?
A: No. The stalk skin is edible. Just wash and chop the rhubarb well.

Q: Can I reduce sugar for a less sweet bar?
A: You can lower the sugar a little, but reduce in small steps to keep the custard texture.
