How to Make Lemon Rhubarb Bars

Step 1: Prepare the Rhubarb Filling

Start by washing and chopping fresh rhubarb into small pieces. Mix the rhubarb with granulated sugar, fresh lemon juice, and lemon zest. Let it sit while you prepare the crust to soften the rhubarb slightly and meld the flavors beautifully.

Step 2: Make the Crust

In a mixing bowl, combine flour, baking powder, salt, and sugar. Cut in chilled unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add the eggs and stir until dough forms, then press about two-thirds of it into a lined baking pan for the base.

Step 3: Assemble and Bake

Spread the rhubarb filling evenly over the crust. Crumble the remaining dough on top for a rustic finish. Bake the bars at 350°F (175°C) for around 35-40 minutes, or until the top is golden and the filling bubbles gently.

Step 4: Cool and Slice

Allow your Lemon Rhubarb Bars to cool completely in the pan so the filling sets properly. Once cooled, cut into small squares, perfect for serving with tea or sharing with friends.

Pro Tips for Making Lemon Rhubarb Bars

• Use fresh rhubarb: Fresh rhubarb ensures the best flavor and texture—frozen can make the filling too watery.
• Don’t overwork the dough: Handle the crust minimally to keep it tender and flaky.
• Adjust sugar to taste: Sweetness can be tweaked depending on how tart your rhubarb is for perfect balance.
• Line the baking pan: Use parchment paper for easy removal and clean slicing.
• Let bars cool completely: This step is crucial for clean cuts without the filling spilling out.

Garnishes

A light dusting of powdered sugar or a few finely grated lemon zest strands on top elevate these bars visually and add an extra hint of citrus aroma.

Creative Ways to Present

Try stacking the bars on a tiered stand for a tea party centerpiece or cut into mini bite-sized pieces for easy finger food during gatherings. You can also drizzle a light lemon glaze for an elegant touch.

Make Ahead and Storage

Storing Leftovers

Store leftover Lemon Rhubarb Bars in an airtight container in the refrigerator for up to 4 days to keep them fresh and flavorful.

Freezing

You can freeze the bars for up to 2 months; just wrap each piece tightly in plastic wrap and place in a freezer-safe container for best results.

Reheating

Warm the bars slightly in the oven at 300°F (150°C) for 5-7 minutes before serving to revive their buttery crust and refreshing filling.

FAQs

Can I use frozen rhubarb for Lemon Rhubarb Bars?

How tart are these bars?

These bars have a balanced tartness thanks to the lemon and rhubarb, mellowed by the sweetness and buttery crust, making them pleasantly tangy without being overpowering.

Can I make the crust vegan?

Yes, substitute butter with coconut oil or vegan margarine and replace eggs with a flaxseed or chia egg to keep the texture and flavor intact.

What’s the best way to slice Lemon Rhubarb Bars?

Use a sharp knife and cut after the bars have completely cooled, wiping the knife clean between cuts for neat, even squares.
