These easy creamy rhubarb custard bars are a perfect balance of tart rhubarb and silky custard, made without a mixer and ideal for spring and summer desserts.

Ingredients

Scale
  • 3 cups fresh rhubarb, chopped into small pieces
  • 1 cup granulated sugar, divided
  • 1 ½ cups all-purpose flour
  • ½ cup (1 stick) cold unsalted butter, cut into cubes
  • 3 large eggs, room temperature
  • 1 cup whole milk
  • 1 teaspoon vanilla extract
  • 2 tablespoons cornstarch
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking pan or line it with parchment paper.
  2. In a large bowl, combine 1 ½ cups flour, ½ cup sugar, and a pinch of salt. Add cold butter cubes and mix with fingers or pastry cutter until mixture resembles coarse crumbs. Press firmly into the bottom of the baking pan.
  3. Partially bake the crust for about 12 minutes until it just starts to turn golden.
  4. In a medium bowl, toss chopped rhubarb with ½ cup sugar and 2 tablespoons cornstarch. Set aside.
  5. In a clean bowl, whisk together eggs, milk, ½ cup sugar, vanilla extract, and a pinch of salt until smooth and slightly frothy.
  6. Spread the rhubarb mixture evenly over the partially baked crust. Pour the custard mixture gently over the rhubarb.
  7. Bake for 30-35 minutes until custard is set but still slightly jiggly in the center.
  8. Cool bars completely to room temperature, then chill in the refrigerator for at least 2 hours.
  9. Slice into squares using a sharp knife dipped in hot water. Serve chilled or at room temperature, optionally with whipped cream or vanilla ice cream.

Notes

Keep butter cold for a flaky crust. Partially bake crust to prevent sogginess. Do not overbake custard to avoid curdling. Cool completely before slicing. If rhubarb is very tart, add an extra tablespoon of sugar to filling. Use a sharp knife dipped in hot water for clean cuts.
