Ingredients
  

  • 2 cups all-purpose flour
  • ¼ cup granulated sugar
  • 1 cup butter cold
  • 2 cups granulated sugar for filling
  • 7 tablespoons flour for filling
  • 1 cup heavy cream
  • 3 large eggs lightly beaten
  • 5 cups finely chopped rhubarb fresh or thawed and drained
  • 6 oz cream cheese softened (for topping)
  • ½ cup granulated sugar for topping
  • ½ teaspoon vanilla extract for topping
  • 1 cup heavy cream whipped (for topping)

Instructions
 

  • Preheat oven to 350°F (175°C). Grease a 13×9-inch baking pan.
  • Make the crust: Combine flour and sugar, cut in cold butter, and press into pan.
  • Bake for 10 minutes.
  • Prepare custard: Mix sugar, flour, cream, and eggs, fold in rhubarb.
  • Pour over crust and bake for 40–45 minutes. Cool.
  • Make topping: Beat cream cheese, sugar, and vanilla, then fold in whipped cream.
  • Spread topping over cooled custard.
  • Refrigerate and chill. Slice and serve.

Notes

  • Use Fresh or Frozen Rhubarb: If using frozen rhubarb, make sure it’s completely thawed and drained before adding to the filling.
  • Chilling Tip: Chilling overnight enhances the flavor and makes slicing easier.
  • Topping Variation: For a citrusy twist, stir lemon zest into the cream cheese layer.
  • Serving Tip: These bars are best served cold with a fork and a napkin—they're creamy and delightfully messy!
