Ingredients
For the Crust

-
1 cup cold butter, cubed
-
1 teaspoon vanilla extract (optional)
For the Custard Filling
-
2 cups sugar
-
7 tablespoons all-purpose flour
-
1 cup heavy whipping cream (or half-and-half/whole milk)
-
3 large eggs, beaten
-
5 cups finely chopped fresh or frozen rhubarb (if frozen, thaw and drain)
For the Cream Cheese Topping
-
6 ounces cream cheese, softened
-
1/2 cup sugar
-
1/2 teaspoon vanilla extract
-
1 cup heavy whipping cream, whipped (or 1 cup thawed whipped topping)
Step-by-Step Instructions
1. Make the Crust
Preheat your oven to 350°F (175°C).
In a bowl, combine flour and sugar. Cut in the cold butter with a pastry blender or two knives until the mixture looks like coarse crumbs. Stir in vanilla if using.
Press the mixture firmly into a greased 9×13-inch baking pan.
Bake for 10–15 minutes, until just set but not browned. Let cool slightly.
2. Prepare the Custard Filling
While the crust bakes, whisk together sugar and flour in a large bowl.
Add the cream and eggs, whisking until smooth. Stir in the chopped rhubarb.
Pour the custard mixture evenly over the warm crust.
3. Bake the Bars
Return the pan to the oven and bake for 40–45 minutes, or until the custard is set and no longer jiggles in the center.
Let the bars cool completely in the pan.
4. Make the Cream Cheese Topping
Beat softened cream cheese, sugar, and vanilla until smooth.
Gently fold in the whipped cream or whipped topping until light and fluffy.
Spread the topping evenly over the cooled bars.
5. Chill and Serve
Cover and refrigerate for at least 1 hour before cutting into bars.
Store leftovers in the fridge.

Tips for Customization
-

-
Fruit Variations: Mix in a handful of strawberries with the rhubarb for a sweeter twist.
-
Lighter Version: Use half-and-half or whole milk in the custard and light cream cheese in the topping.
