Ingredients

2 cups all-purpose flour
1/4 cup sugar
1 cup cold butter

Filling:

2 cups sugar
7 tablespoons all-purpose flour
1 cup heavy whipping cream
3 large eggs, beaten
5 cups finely chopped rhubarb (fresh or frozen, thawed and drained)

Topping:

6 ounces cream cheese, softened
1/2 cup sugar
1/2 teaspoon vanilla extract
1 cup heavy whipping cream, whipped

Step-by-Step Instructions

Preparing the Ingredients

Start by preheating your oven to 350°F and greasing a 13×9-inch baking pan. Then, combine flour and sugar in a bowl before cutting in the cold butter until coarse crumbs form. Press this mixture evenly into the pan to create a firm base while you prepare the filling and topping components.

Cooking Instructions

Bake the crust for 10 minutes until lightly set. Meanwhile, whisk together sugar and flour for the filling, then mix in cream and beaten eggs until smooth. Stir in the rhubarb and pour the mixture over the pre-baked crust. Bake for 40–45 minutes until the custard sets. Let it cool completely before preparing the topping. Beat cream cheese, sugar, and vanilla until smooth, then gently fold in whipped cream. Spread over the cooled bars and refrigerate for about one hour until firm enough to slice.

Tips for Perfect Results

Common Mistakes to Avoid

Avoid using overly wet rhubarb, as excess moisture can prevent the custard from setting properly. Also, do not skip pre-baking the crust because it helps keep the base firm instead of soggy. Always allow the bars to cool fully before adding the topping to maintain structure.

Pro Tips for Better Flavor

Use fresh rhubarb when available for a brighter flavor, although frozen works well when properly drained. For a richer taste, chill the bars longer before serving so the layers set beautifully. Additionally, cut the bars with a clean, sharp knife for neat edges.

Serving and Storage

How to Serve

Serve Viral Rhubarb Custard Bars chilled for the best texture and flavor. These bars pair perfectly with coffee or tea, making them ideal for brunch, dessert tables, or afternoon treats.

How to Store Leftovers

Store leftover bars in an airtight container in the refrigerator for up to 4 days. For best results, keep them chilled and avoid leaving them at room temperature for long periods.
