How to Make Rhubarb Shortbread Bars

Step 1: Prepare the rhubarb filling

Start by washing and chopping fresh rhubarb into small pieces. Combine it with granulated sugar in a saucepan and cook over medium heat until the rhubarb softens and releases its juices, forming a thick, jam-like consistency. Let it cool completely before assembling.

Step 2: Make the shortbread crust

In a mixing bowl, cream together unsalted butter, brown sugar, and vanilla extract until light and fluffy. Gradually add all-purpose flour and salt, mixing until crumbly dough forms.

Step 3: Press the crust into the pan

Reserve about one-third of the dough for topping. Press the remaining dough evenly into the bottom of a greased baking pan, creating a firm, even base.

Step 4: Add the rhubarb filling

Spread the cooled rhubarb filling evenly over the crust, making sure to cover the surface without spilling over edges.

Step 5: Top and bake

Crumble the reserved dough on top of the rhubarb filling, creating a crumbly “streusel” effect. Bake in a preheated oven at 350°F (175°C) for about 40-45 minutes until the top is golden and the filling bubbles softly.

Step 6: Cool and slice

Let the bars cool completely in the pan before cutting into squares. This ensures clean slices and the perfect texture.

Pro Tips for Making Rhubarb Shortbread Bars

• Use fresh, firm rhubarb: Avoid overly soft or wilted stalks to ensure a bright, flavorful filling.
• Don’t skip cooling the filling: Spreading warm filling can cause the crust to become soggy.
• Press crust firmly: A compact base prevents crumbling when serving.
• Chill dough before baking: If your kitchen is warm, cool the dough to maintain its texture.
• Try lined pans: Use parchment paper to help lift bars cleanly from the pan.

How to Serve Rhubarb Shortbread Bars

Garnishes

Make Ahead and Storage

Storing Leftovers

Keep any leftover bars in an airtight container at room temperature for up to two days or in the fridge for up to a week to maintain freshness and texture.

Freezing

Wrap the bars tightly in plastic wrap and place them in a freezer-safe container or bag. Freeze for up to three months, then thaw overnight in the refrigerator before serving.

Reheating

Reheat bars gently in a warm oven (around 300°F or 150°C) for 5-10 minutes to restore warmth and softness without drying them out.
