Step‑by‑Step Instructions for Rhubarb Shortbread Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Prepare a 9×13-inch baking pan by lining it with parchment paper or lightly greasing it. This ensures that your Rhubarb Shortbread Bars will release easily after baking, allowing for clean and even slices once they’re ready to serve.

Step 2: Prepare the Shortbread Crust
In a mixing bowl, combine 2 cups of all-purpose flour, ½ cup of powdered sugar, and a pinch of salt. Cut in 1 cup of cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This crumbly texture is essential for achieving the buttery base. Once mixed, press the dough evenly into the bottom of the prepared pan.

Step 3: Bake the Crust
Place the pan in the preheated oven and bake the crust for 15–20 minutes, or until it is lightly golden around the edges. Keep an eye on the crust to avoid over-baking, as you want it firm but still soft. Once baked, remove it from the oven and let it cool slightly while you prepare the filling.

Step 4: Make the Filling
In a separate bowl, whisk together 3 eggs until they are frothy, then mix in 2 cups of granulated sugar, ½ cup of all-purpose flour, and ½ teaspoon of baking powder. Blend the mixture until smooth, creating a luscious filling. Gently fold in 3 cups of chopped rhubarb, ensuring the fruit is evenly distributed throughout the filling for balanced flavor in your Rhubarb Shortbread Bars.

Step 5: Assemble and Bake Again
Pour the rhubarb filling over the pre-baked crust, spreading it evenly with a spatula. Return the pan to the oven and bake for an additional 40–45 minutes, watching for the filling to set and become golden on top. It’s done when a toothpick inserted in the center comes out clean or with moist crumbs attached.

Step 6: Cool and Cut
Once baked, remove the Rhubarb Shortbread Bars from the oven and let them cool completely in the pan. This step is crucial to ensure clean cuts, as the bars might crumble if still warm. Once cooled, slice into squares or rectangles and get ready to enjoy this delightful sweet-tart treat!

Rhubarb Shortbread Bars Recipe FAQs

How do I select the best rhubarb for my Rhubarb Shortbread Bars?
Look for rhubarb stalks that are firm and vibrant in color. The stalks should be crisp and free of dark spots or blemishes. If you’re choosing between varieties, generally, the red-stalked rhubarb is sweeter, while the green-stalked variety has a more tart flavor, which could create a delightful contrast in your bars!

What’s the best way to store Rhubarb Shortbread Bars?
To keep your Rhubarb Shortbread Bars fresh, store them in an airtight container in the refrigerator, where they’ll stay good for up to 5 days. This helps maintain their delightful texture and flavor while keeping them moist. For the best enjoyment, bring them to room temperature before serving.

Can I freeze Rhubarb Shortbread Bars?
Absolutely! To freeze the bars, wrap them tightly in plastic wrap and place them in a freezer-safe container. They can last in the freezer for up to 2 months. When you’re ready to enjoy them, simply thaw the bars in the refrigerator overnight or at room temperature for a few hours.

What should I do if my filling doesn’t set properly?
If your filling comes out runny, it might be due to excess moisture in the rhubarb. To ensure this doesn’t happen, slice the rhubarb and let it drain in a colander for about 30 minutes to remove some moisture before adding it to your mixture. Additionally, make sure to properly bake the filling until it’s golden and set—cooking it for a little longer may help it firm up!

Are Rhubarb Shortbread Bars suitable for people with dietary restrictions?
Yes, they can be! You can easily make a gluten-free version by substituting all-purpose flour with a gluten-free flour blend. For a dairy-free option, simply replace butter with margarine. Always let your guests know about any ingredients to avoid cross-contamination, especially to cater to allergies!
