Instructions

  • Preheat oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides to lift the bars out later.
  • Make the shortbread crust: In a large bowl, cream together the softened butter and sugar until light and fluffy. Gradually add the flour and salt, mixing until just combined. Do not overmix.
  • Press the dough evenly into the prepared baking pan.
  • Make the rhubarb filling: In a separate bowl, combine the chopped rhubarb, sugar, cornstarch, vanilla extract, and cinnamon (if using). Toss gently to coat.
  • Spread the rhubarb filling evenly over the shortbread crust.
  • Bake for 30-35 minutes, or until the crust is golden brown and the filling is bubbly and slightly thickened. Let cool completely in the pan before lifting out using the parchment paper overhang.
  • Once cooled, cut into squares or rectangles and serve.

Notes

For a richer flavor, use brown sugar instead of granulated sugar in the crust. You can also add a sprinkle of coarse sugar on top of the rhubarb filling before baking for extra crunch.

Detailed Steps for Making Rhubarb Shortbread Bars

Follow these detailed steps to create irresistible Rhubarb Shortbread Bars. Remember, precision and attention to detail are key to baking success. Enjoy the process and the delicious outcome!

Step 1: Prepare the Shortbread Crust

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper. This prevents sticking and ensures easy removal of the bars later.
  2. In a large bowl, cream together the softened butter and sugar until light and fluffy. An electric mixer is highly recommended for this step – it saves time and ensures even mixing. If you’re using a hand mixer, make sure to scrape down the sides of the bowl regularly.
  3. Gradually add the flour and salt, mixing until just combined. Be careful not to overmix – overmixing can result in a tough shortbread.
  4. Press the shortbread dough evenly into the prepared baking pan. Use the bottom of a measuring cup or your fingers to ensure an even layer.

Step 2: Prepare the Rhubarb Filling

  1. In a separate bowl, combine the chopped rhubarb, sugar, cornstarch, vanilla extract, and cinnamon (if using). Gently mix until well combined.
  2. Pour the rhubarb mixture evenly over the prepared shortbread crust.

Step 3: Bake the Rhubarb Shortbread Bars

  1. Bake for 35-40 minutes, or until the crust is golden brown and the filling is bubbly and slightly thickened. **Keep a close eye on your bars during the last 10-15 minutes of baking to avoid burning.**
  2. Let the bars cool completely in the pan before cutting. This is crucial to prevent the bars from crumbling. Cooling completely also allows the filling to set properly.
  3. Once cooled, cut the bars into squares or rectangles. A sharp knife will give you clean, even cuts.

Step 4: Serve and Enjoy!

Once the Rhubarb Shortbread Bars have completely cooled, they’re ready to be served. You can store them in an airtight container at room temperature for up to 3 days. Enjoy this delightful treat! They’re amazing on their own or served with a dollop of whipped cream or a scoop of vanilla ice cream. For an extra touch, try sprinkling a little powdered sugar on top before serving.
