Step-by-Step Instructions for Rhubarb Custard Bars
Alright, my dears, let’s get started! I’ll walk you through each step, just like I would if you were right here in my kitchen.
- Prepare the Crust: Preheat the oven to 350°F. In a bowl, combine the flour and sugar. Cut in very cold cubes of butter until the mixture resembles coarse crumbs. Press into a greased 13×9-inch baking pan. Bake for 10 minutes. Let cool briefly before filling. Editor’s Tip: Cut the butter into the flour using a pastry blender or two knives. Or use a food processor. Just use a delicate finger on the pulse button and stop when the mixture looks like crumbs. PS: If you’re cooking for a smaller crowd, you can halve this recipe and bake it in an 8- or 9-inch square pan.
- Make the Custard Filling: While the crust is baking, combine the sugar and flour in a bowl. Whisk in the cream and eggs until the mixture is uniform, and stir in the rhubarb. Pour the mixture over the crust, and bake until the custard sets, 40 to 45 minutes. Let cool.
- Prepare the Cream Cheese Topping: For the topping, beat the cream cheese, sugar and vanilla until smooth, then fold in the whipped cream. Spread the cream cheese mixture over the cooled custard bars. Cover and chill. When cool, cut into bars and store in the fridge. Editor’s Tip: When you fold ingredients together, use a gentle sweeping motion that starts at the bottom of the bowl and swoops up. Anything more aggressive, and you’ll deflate the fluffy whipped cream.
And there you have it! See how easy that was? The rhubarb bars are practically begging to be eaten!
Pro Tips for Perfect Rhubarb Custard Bars
Now, darlings, here are a few of Grandma Rose’s secret tips to ensure your Rhubarb Custard Bars are absolutely perfect:
- Use Cold Butter: Cold butter is crucial for a flaky crust. If the butter gets too warm, the crust will be tough. Roach South always reminds me of this.
- Don’t Overmix the Crust: Overmixing develops the gluten in the flour, resulting in a tough crust. Mix until just combined.
- Drain the Rhubarb Well: Excess moisture from the rhubarb can make the custard soggy. Drain it thoroughly before adding it to the mixture.
- Let the Bars Cool Completely: Patience is key! Let the bars cool completely before adding the cream cheese topping. This will prevent the topping from melting.
- Chill Before Serving: Chilling the bars allows the flavors to meld together and the topping to set properly.
Remember, the secret is patience. Take your time, follow the steps, and you’ll be rewarded with the most delicious Rhubarb Custard Bars.
Common Mistakes to Avoid
Even the best of us make mistakes, darling. But don’t you worry, I’m here to help you avoid some common pitfalls when making these Rhubarb Custard Bars:
- Soggy Crust: This usually happens when the rhubarb isn’t drained properly or the crust isn’t baked long enough.
- Runny Custard: Make sure the custard is fully set before removing the bars from the oven. If it’s still jiggly, bake it for a few more minutes.
- Melting Topping: Always let the bars cool completely before adding the cream cheese topping.
- Tough Crust: Overmixing the crust ingredients can lead to a tough crust. Handle the dough gently.
- Bland Flavor: Don’t be afraid to adjust the amount of sugar to your liking. If you prefer a sweeter bar, add a little extra sugar to the filling.
If you encounter any of these issues, don’t fret! Just learn from your mistakes and try again. Baking is all about practice and experimentation.
Variations on Grandma Rose’s Rhubarb Custard Bars
Now, my dears, let’s talk about how you can put your own spin on this classic recipe. Here are a few variations to try:
- Strawberry Rhubarb: Add a cup of sliced strawberries to the rhubarb filling for a sweeter, more complex flavor.
- Ginger Rhubarb: Add a teaspoon of ground ginger to the filling for a warm, spicy kick.
- Almond Rhubarb: Add a quarter teaspoon of almond extract to the cream cheese topping for a nutty flavor.

How to Store Rhubarb Custard Bars
To keep your Rhubarb Custard Bars fresh and delicious, follow these storage tips:
- Refrigerate: Store the bars in an airtight container in the refrigerator for up to 3-4 days.

- Thawing: Thaw the frozen bars in the refrigerator overnight before serving.
Remember, the cream cheese topping may soften slightly after thawing, but the bars will still taste delicious!
