How to Make Creamy Rhubarb Custard Bars

Creamy rhubarb custard bars begin with a soft buttery shortbread crust baked until lightly golden. While the crust bakes, the rhubarb releases its juices and blends beautifully into a creamy custard mixture.

After pouring the filling over the warm crust, the bars bake until the center becomes lightly set with a slight jiggle. Chilling the dessert fully helps the custard firm up and creates clean slices with smooth creamy layers.

Step-by-Step Instructions

1. Preheat the oven to 350°F (175°C). Prepare a 9×13-inch baking pan with parchment paper or grease lightly.
2. Beat the softened butter and 1/2 cup sugar together until fluffy and light. Add 1 teaspoon vanilla extract and mix briefly.
3. Whisk together 2 cups flour and 1/4 teaspoon salt in another bowl. Slowly combine the dry ingredients with the butter mixture until crumbly dough forms.
4. Press the dough evenly into the prepared pan. Bake for 15 to 18 minutes until the edges become lightly golden.
5. Toss the chopped rhubarb with 1 tablespoon sugar while the crust bakes. Let it rest for 10 minutes.
6. In a mixing bowl, whisk together eggs, remaining sugar, flour, vanilla extract, and pinch of salt until smooth.
7. Slowly whisk in heavy cream and whole milk until creamy and fully blended.
8. Fold the rhubarb and its juices gently into the custard mixture.
9. Pour the filling evenly over the warm baked crust.
10. Bake for another 30 to 35 minutes until the custard looks set but slightly jiggly in the center.
11. Cool completely at room temperature before refrigerating for at least 2 hours.
12. Slice into bars using a warm sharp knife for neat edges.

Helpful Tips

• Use fresh rhubarb for the best flavor and texture.
• Avoid overbaking because the custard continues setting while cooling.
• Refrigerate fully before slicing for cleaner bars.
• Drain thawed frozen rhubarb well to reduce extra moisture.
• Use parchment paper for easy lifting and slicing.
• Wipe the knife between cuts for smooth presentation.
