Rhubarb Dream Bars

Featured in Irresistible Desserts.

These tangy rhubarb bars feature a crisp, buttery crust beneath a smooth, custardy layer packed with vibrant rhubarb. The crust comes together quickly with just flour, sugar, and butter, forming the perfect base for the creamy filling. Whisked eggs combine with sugar and a touch of flour, balancing the tartness of rhubarb. Baked until golden and set, the squares are easy to lift from the pan thanks to parchment, and deliver a blend of textures and flavors that's bright, a little tangy, and altogether refreshing. Enjoy them chilled or at room temperature for any casual spring or summer gathering.

Ingredients

  • All purpose flour: for the crust and filling gives a tender base and helps set the creamy top layer For best results use freshly purchased flour that is clump free
  • Sugar: adds sweetness and balances the sharpness of rhubarb Go for fine granulated sugar for smooth blending
  • Butter: room temperature makes the crust rich and easy to press in the pan Choose a good quality unsalted butter for best flavor
  • Large eggs: are the key to the creamy filling Select the freshest eggs for a custardy texture
  • Salt: enhances all the flavors and keeps the crust from tasting flat Use fine sea salt
  • Rhubarb: diced provides the signature tartness and color Look for firm crisp stalks no limp or woody pieces
