How to Make Rhubarb Shortbread Bars
Step 1: Prepare the Rhubarb Filling
Start by chopping the rhubarb into small pieces. Combine it with sugar, cornstarch, and lemon zest in a bowl to create a thick, tangy filling. Let it sit for 10 minutes so the flavors meld and the juices start to release.
Step 2: Make the Shortbread Crust
In a separate bowl, mix softened butter, granulated sugar, brown sugar, vanilla extract, and salt until creamy. Gradually add flour until the dough comes together as a crumbly but workable shortbread mixture.
Step 3: Assemble the Bars
Press about two-thirds of the shortbread dough firmly into a greased baking pan, creating an even base layer. Spoon the rhubarb filling evenly over the crust, spreading it gently. Crumble the remaining dough over the top for a crumbly finish.
Step 4: Bake to Perfection
Bake the bars in a preheated oven at 350°F (175°C) for 35 to 40 minutes, or until the top is golden and the filling is bubbling. Allow to cool completely before slicing into squares.
Step 5: Serve and Enjoy
Once cooled, cut the slab into bars and savor the blend of buttery crust and tangy rhubarb. These bars can be enjoyed at room temperature or slightly chilled.
Pro Tips for Making Rhubarb Shortbread Bars
- Use Fresh Rhubarb: Fresh stalks yield the best flavor and texture compared to canned or frozen options.
- Don’t Overmix the Dough: Keeping the shortbread dough crumbly ensures a tender, flaky crust.
- Chill the Dough: Refrigerate the shortbread dough before baking to help maintain its shape and improve texture.
- Adjust Sweetness: Rhubarb is naturally tart, so taste the filling before baking and add more sugar if needed.
- Use a Sharp Knife: Cut the bars with a sharp knife to achieve clean, neat edges without crumbling.
How to Serve Rhubarb Shortbread Bars
Garnishes
Sprinkle powdered sugar over the bars for an elegant look, or add a drizzle of vanilla glaze for extra sweetness and a shiny finish. Fresh mint leaves also add a refreshing touch.
Side Dishes
Pair Rhubarb Shortbread Bars with a scoop of vanilla ice cream or a dollop of freshly whipped cream to balance the tartness beautifully. A cup of hot tea or coffee enhances the cozy experience.
Creative Ways to Present
Serve the bars on a rustic wooden board lined with parchment paper for a charming presentation. You can also stack mini bars for a fun dessert platter, or use colorful plates to highlight the rhubarb’s vivid pink hue.
Make Ahead and Storage
Storing Leftovers
Keep leftover bars in an airtight container at room temperature for up to two days, or refrigerate for up to a week to maintain freshness and flavor.
Freezing
Wrap individual bars tightly with plastic wrap and aluminum foil, then freeze for up to three months. Thaw overnight in the fridge before serving.
Reheating
Warm bars gently in the oven at 300°F (150°C) for 10-12 minutes to refresh the buttery crust and soften the filling. Avoid microwaving to prevent sogginess.
