Ingredients

Crust Ingredients

  • 1 cup all-purpose flour A staple that creates a delicate, crumbly base for your bars.

  • 2 tbsp sugar Just enough to sweeten the crust.

Custard Filling Ingredients

  • 2 large eggs Provides structure and moisture.
  • 1 cup sugar Balances the tartness of the rhubarb.
  • 1/4 cup all-purpose flour Helps to bind the filling together.
  • 1/4 tsp salt Enhances the overall flavor.
  • 2 cups chopped rhubarb Brings a bright, tangy freshness.

Instructions

Preparation

  • Preheat your oven to 350°F (175°C).
  • In a mixing bowl, combine 1 cup of all-purpose flour, ½ cup of cold, cubed butter, and 2 tablespoons of sugar. Use a pastry cutter or your fingers to work the mixture until it resembles coarse crumbs.
  • Press the mixture into a greased 8×8-inch pan evenly.
  • Bake the crust for 12-15 minutes, or until it’s lightly golden.

Custard Filling

  • In a separate bowl, whisk together 2 large eggs, 1 cup of sugar, ¼ cup of all-purpose flour, and ¼ teaspoon of salt until well combined.
  • Gently fold in the 2 cups of chopped rhubarb, ensuring every piece is coated.
  • Pour the filling over the hot crust, spreading it evenly.
  • Bake for 35-40 minutes until the filling is set and lightly golden on top.
  • Let cool completely in the pan before slicing into squares.

Notes

For best flavor, use fresh rhubarb. If using frozen, thaw and drain before using. Adjust sugar to taste.
