Step‑by‑Step Instructions for Rhubarb Custard Bars
Step 1: Preheat and Prepare the Kitchen
Begin by preheating your oven to 350°F (175°C). While the oven warms, gather your equipment: a mixing bowl, a measuring cup, and a 9×13-inch baking dish. Lightly grease the baking dish with butter or cooking spray to ensure easy removal of your delicious Rhubarb Custard Bars later.
Step 2: Make the Crust Mixture
In a large mixing bowl, combine the all-purpose flour and powdered sugar, whisking them together until well blended. Next, add the cold, cubed butter. Using a pastry cutter or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. This will create a flaky crust for your bars.
Step 3: Form the Crust and Bake
Once the crust mixture is ready, transfer it to the greased baking dish. Use your fingertips to press it evenly across the bottom, ensuring a compact layer. Place the dish in the preheated oven and bake for about 15 minutes, until the crust is lightly golden. Keep an eye on it to avoid overbaking.
Step 4: Prepare the Custard Filling
As the crust bakes, whisk together the eggs, granulated sugar, flour, and salt in a large bowl until smooth. Make sure there are no lumps remaining. Once combined, gradually stir in the heavy cream, followed by the chopped fresh rhubarb, creating a delicious custard mixture that will be poured over the crust.
Step 5: Combine and Pour
After the crust is baked, carefully remove it from the oven and let it cool for a few minutes. Pour the prepared custard mixture over the crust, spreading it evenly with a spatula. This will ensure that every bite of your Rhubarb Custard Bars is wonderfully balanced in flavor and texture.
Step 6: Bake the Custard Bars
Return the baking dish to the oven and bake for 40 to 45 minutes. The custard is finished when it is set around the edges but slightly jiggly in the center, with a light golden top. Keep an eye on it during the last few minutes of baking to achieve that perfect texture.
Step 7: Cool and Refrigerate
Once baked, remove the Rhubarb Custard Bars from the oven and allow them to cool at room temperature. After they have cooled completely, refrigerate the bars for at least 2 hours. This chilling step is crucial for achieving clean, neat slices when you’re ready to serve them.
Step 8: Slice and Serve
When you’re ready to indulge, take the bars out of the fridge. Using a sharp knife, slice them into squares or rectangles, depending on your preference. For an extra touch of sweetness, dust them with powdered sugar before serving, and enjoy these delightful Rhubarb Custard Bars with family and friends!

Rhubarb Custard Bars Recipe FAQs
What type of rhubarb is best for this recipe?
Absolutely! Look for rhubarb stalks that are firm and vibrant, ideally a deep red or pink color. Avoid any that show signs of wilting or have dark spots all over, as these can indicate overripeness or spoilage. Fresh rhubarb brings the best tart flavor to your Rhubarb Custard Bars, but if it’s out of season, frozen rhubarb works just fine—just ensure you thaw and drain it first for the best results.

How should I store my Rhubarb Custard Bars?
You can store your bars in an airtight container in the refrigerator for up to 4 days. This keeps them fresh while preserving that delightful creamy custard texture. If you’re making a batch for later, take care to ensure they have cooled completely before sealing them in to avoid condensation.
Can I freeze Rhubarb Custard Bars?
Certainly! To freeze your Rhubarb Custard Bars, allow them to cool completely, then place them in an airtight container or wrap them tightly in plastic wrap. They will keep well in the freezer for up to 2 months. When you’re ready to enjoy them, simply transfer the bars to the refrigerator to thaw overnight. This method helps keep their texture intact!
What if my custard doesn’t set properly?
If you find that your custard is too runny after baking, it may have been undercooked—a common issue when using a different oven or baking dish. Always check for that light jiggle in the center as a sign of doneness; it should not be liquid. In this case, you can increase the baking time by 5-10 minutes while keeping a close watch. For future attempts, ensure that you’ve mixed the ingredients thoroughly without any lumps!
Are Rhubarb Custard Bars suitable for people with dietary restrictions?
Very! For those on a gluten-free diet, using a gluten-free all-purpose flour blend is an excellent alternative that won’t sacrifice flavor or texture. Additionally, you can make a vegan version by substituting the eggs with flax eggs—simply mix 1 tablespoon of ground flaxseed with 3 tablespoons of water for each egg, let it sit for 5-10 minutes until it becomes gelatinous, and then add it to your custard mixture. Feel free to ask for more specifics on dietary substitutions!
