Simple to make and bursting with flavor, this rhubarb dessert is perfect for brunch, picnics, or anytime you’re craving a sweet-tart treat. Chill, slice, and serve for a delicious seasonal bite!


Ingredients

  • For the Crust:
  • 1 1/2 cups all-purpose flour
  • 1/3 cup granulated sugar
  • 3/4 cup unsalted butter, softened
  • For the Filling:
  • 3 large eggs
  • 1 1/4 cups granulated sugar
  • 1/4 cup all-purpose flour
  • 1 cup heavy cream or half-and-half
  • 1 1/2 teaspoons vanilla extract
  • 2 cups rhubarb, chopped (fresh or frozen and well-drained)

Instructions

  1. Preheat oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment or lightly grease.

  2. In a bowl, mix flour and sugar for the crust. Cut in butter until mixture resembles coarse crumbs.

  3. Press evenly into the bottom of the prepared dish.

  4. Bake crust for 10–12 minutes, or until lightly golden.

  5. While the crust bakes, whisk together eggs, sugar, flour, cream, and vanilla until smooth.

  6. Fold in chopped rhubarb.

  7. Pour custard over the hot crust and return to oven.

  8. Bake for 40–45 minutes, or until custard is set and golden on top.

  9. Cool completely, then chill for at least 1 hour before slicing.


Notes

  • Add lemon or orange zest to brighten the custard.
  • Sprinkle cinnamon or nutmeg for cozy warmth.
  • Dust with powdered sugar or drizzle with glaze once cooled.
  • Strawberry-rhubarb combos are also delicious.
  • Coconut milk works for a dairy-free variation.
