• 7 tablespoons all-purpose flour

Step-by-Step Instructions

Preparing the Crust

1. In a mixing bowl, combine 2 cups of all-purpose flour and ¼ cup of sugar. Mix well to combine.
2. Add 1 cup of cold butter, cut into cubes, into the flour mixture. Use a pastry cutter or your fingers to blend until the mixture is crumbly and resembles coarse crumbs.
3. Press the crust mixture evenly into the bottom of your prepared baking dish, ensuring it's compact and level.

Baking the Crust

4. Preheat your oven to 350°F (175°C) while you prepare the crust.
5. Bake the crust in the preheated oven for 20 minutes, or until it is just golden brown around the edges.
6. Remove the crust from the oven and let it cool slightly for about 10 minutes.

Making the Filling

7. In a clean mixing bowl, combine 2 cups of sugar, 7 tablespoons of all-purpose flour, and 1 cup of heavy whipping cream.
8. Add in 3 large beaten eggs and 5 cups of finely chopped rhubarb, mixing well until everything is fully combined.
9. Pour this luscious filling over the cooled crust, spreading it evenly to cover the surface.

Baking the Bars

10. Bake the bars in the oven for another 25 minutes, or until the filling is set and a slight jiggle remains in the center.
11. Take the bars out of the oven and let them cool completely at room temperature. This allows the filling to firm up.

Preparing the Topping

12. In a mixing bowl, beat together 6 ounces of softened cream cheese, ½ cup of sugar, and ½ teaspoon of vanilla extract until smooth and creamy.
13. Gently fold in 1 cup of whipped heavy cream until fully incorporated, creating a fluffy topping.

Assembling and Chilling

14. Spread the cream cheese topping evenly over the cooled filling, smoothing it out with a spatula.
15. Cover the baking dish and chill in the refrigerator for at least 2 hours before serving. This helps the flavors meld beautifully.

Variations

• Substitute half of the rhubarb with strawberries for a delightful strawberry-rhubarb twist.
• Add a teaspoon of almond extract to the filling for a nutty flavor boost.
• For a gluten-free option, replace all-purpose flour with a gluten-free flour blend.
• Top with fresh berries or a sprinkle of toasted coconut for added texture and flavor.
• Try adding a pinch of cinnamon or nutmeg to the filling for a warm, cozy spice.

Serving and Storage Tips

Serving

Serve the Rhubarb Custard Bars chilled, cut into squares, and enjoy with a dollop of whipped cream or a scoop of vanilla ice cream. They pair wonderfully with a cup of tea or coffee, making them a delightful treat for any occasion.

Storage

Store the bars in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze the bars wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw in the fridge before serving.

Common Mistakes

• Not cooling the crust: If the crust is too hot when adding the filling, it can cause the filling to cook unevenly. Always let it cool slightly.
• Using too much rhubarb: Overloading with rhubarb can make the bars too watery. Stick to the recommended amount for best results.
• Skipping the chilling step: Chilling the bars allows the flavors to meld and the topping to set properly. Don't rush this step!
• Not measuring accurately: Baking is precise; using incorrect measurements can affect the texture. Always measure ingredients carefully.

Helpful Notes

• For a dairy-free option, substitute heavy cream with coconut cream and use a dairy-free cream cheese.
• Add a handful of chopped nuts to the crust for extra crunch and flavor.
• If you prefer a sweeter bar, increase the sugar in the filling slightly, especially if using tart rhubarb.
• Experiment with different extracts, such as lemon or orange, for a refreshing twist.
