Rhubarb Crumb Bars

Roberta Reynolds
The first sign of spring in many gardens is the sight of little leaves of rhubarb peeking through the earth (and sometimes even the snow!). When weather turns warm enough to be outside for a while in the sun, our thoughts turn to a spring picnic. These bars are a nice treat, pack easily and will travel with you wherever you go. They are also a nice snack or quick desert any time.

  • Sprinkle on top of Crumb Bar Base.
  • CRUMB TOPPING
  • Stir together melted butter, brown sugar, and salt.
  • Lightly stir in flour, then ‘smoosh’ mixture together with your fingers so flour forms clumps.

  • Bake at 350 degrees for about 60-80 minutes, or until internal center temperature reaches 210 degrees.
  • Cool, cut into bars, and serve.
