Ingredients You’ll Need
For the crust: You may also find 7 Easy Rhubarb Desserts useful.
- 1 cup (2 sticks) unsalted butter, softened
- 1/2 cup powdered sugar
- 2 cups all-purpose flour
- 1/4 teaspoon salt
For the custard:
- 4 large eggs
- 1 1/2 cups granulated sugar
- 1/2 cup all-purpose flour
- 1/2 cup heavy cream or whole milk
- 1 teaspoon vanilla extract
- 2 1/2 cups fresh rhubarb (chopped into 1/2-inch pieces)
Using real butter for the crust makes every bite heavenly and ensures that your bars will have that inviting melt-in-your-mouth quality.
Step-by-Step Directions
Preheat your oven to 350°F (175°C). Line a 9×13-inch metal baking pan with parchment paper, extending it over two sides for easy lifting later.
Make the crust: In a large bowl, beat the softened butter and powdered sugar together until creamy. Next, add the flour and salt and mix until the dough just comes together and feels soft to the touch. Press this mixture evenly into the bottom of the prepared pan for a secure base.
Pre-bake the crust for 18-22 minutes, or until the edges are lightly golden brown, signaling readiness. Remove from the oven to cool slightly.
Make the custard: In another bowl, whisk together the eggs, granulated sugar, flour, cream, and vanilla until completely smooth. Gently fold in the chopped rhubarb, covering it evenly with the custard mixture.
Carefully pour the custard mixture over the pre-baked crust and spread it evenly, ensuring each bite is balanced with a mix of crust and filling.
Bake for 40-45 minutes until the edges are set and the center has a slight jiggle but isn’t runny. The surface should look glossy and inviting.
Allow the bars to cool completely at room temperature, which takes about 1.5 to 2 hours. Refrigerate them for at least 1 hour to fully set before slicing.
With the parchment overhang, lift the bars out of the pan, slice them into squares, and serve chilled, allowing everyone to enjoy the delightful flavors.
The beauty of these bars lies in their contrasting textures—thick, buttery crust paired with a smooth, creamy custard filling. They promise not only excellent taste but also a joyous baking experience.
