- 1/2 tsp vanilla extract

Ingredient Notes and Easy Substitutions
- Rhubarb: Fresh rhubarb is best when in season, but you can easily use frozen rhubarb. Just make sure to thaw and drain any excess liquid before using.
- Cream Cheese: For a lighter option, you can substitute Greek yogurt for the cream cheese in the frosting.
- Cool Whip: If you’re looking for a homemade alternative, you can whip your own heavy cream with a touch of sugar until soft peaks form and use that in place of Cool Whip.
- Flour: Make sure to use all-purpose flour for the best texture. If you’re gluten-free, consider using a gluten-free flour blend.
Instructions
- Preheat your oven to 350°F (175°C).
- Prepare the crust: In a mixing bowl, combine 1.5 cups of flour, 1/3 cup sugar, and salt.
- Add the cold, cubed butter and cut it into the flour mixture until it resembles coarse crumbs.
- Press the mixture evenly into the bottom of a 9×13 inch baking pan lined with parchment paper.
- Bake the crust for about 15 minutes, or until it’s lightly golden.
- Prepare the filling: In another bowl, whisk together 1/3 cup flour, 1 cup sugar, milk, and eggs until well combined, then stir in the sliced rhubarb.
- Pour the rhubarb mixture over the baked crust and bake for an additional 40-45 minutes, or until the filling is set.
- Allow the bars to cool to room temperature.
- Make the frosting: Beat cream cheese, vanilla extract, and Cool Whip together until smooth, then gradually add powdered sugar to taste.
- Spread the frosting over the cooled rhubarb bars, cut into squares, and serve.
- Store leftovers in the refrigerator.
Expert Tips for the Best Results
- Chill the Ingredients: Ensure that your butter and cream cheese are cold for the best texture.
- Don’t Rush the Cooling: Allow the bars to cool completely before adding the frosting. This prevents it from melting and ensures a smooth finish.
- Test for Doneness: The filling should be set but slightly jiggly in the center when you take it out of the oven.
Variations
- Nutty Crust: Add chopped nuts to the crust for extra crunch and flavor.
- Mixed Fruits: Consider adding strawberries or blueberries for a mixed berry filling.
- Spiced Up: Add a teaspoon of cinnamon or nutmeg to the custard for a warm spice touch.
- Lemon Zing: A splash of lemon juice or zest in the custard can brighten up the flavors.
- Chocolate Drizzle: Drizzle melted chocolate over the frosting for an extra indulgent touch.
Serving Suggestions
These Rhubarb Custard Bars can be enjoyed on their own, but they pair delightfully with a variety of accompaniments. Serve them with a scoop of vanilla ice cream, a dollop of whipped cream, or even a drizzle of caramel sauce for added sweetness. Pair them with a refreshing iced tea or a bright lemonade for the ultimate spring or summer treat.
Storage and Reheating
Store any leftover Rhubarb Custard Bars in an airtight container in the refrigerator. They can last up to 4-5 days stored this way. For best results, let them come to room temperature before serving again. If you’re making these bars ahead of time, they can be prepared a day in advance and stored in the refrigerator until you’re ready to serve.
Common Mistakes to Avoid
- Miscalculating Baking Time: Keep an eye on the baking time for both the crust and the filling; underbaked bars may be too gooey while overbaked ones may become dry.
- Not Cooling Properly: Skipping the cooling step can cause the frosting to melt and ruin the final appearance.
- Overmixing: When combining the frosting ingredients, mix just until smooth to keep it from becoming too runny.
FAQ
- Can I freeze these bars? Yes, you can freeze the uncut bars. Wrap them tightly in plastic wrap and aluminum foil. Thaw in the refrigerator before serving.
- What can I substitute for eggs in the recipe? You can use flaxseed meal mixed with water or a commercial egg replacer.
- Can I use a different type of fruit? Absolutely! Many fruits work well with this recipe. Apples and cherries can be great alternatives to rhubarb.
- How do I know when the filling is set? The filling should be slightly jiggly in the center but firm around the edges when done.
- What type of rhubarb should I use? Both fresh and frozen rhubarb can be used, though fresh usually provides the best flavor.
