Compared to the average fruit bar recipe (which takes about 75–90 minutes), this version shaves off about 20% of your kitchen time while offering even better results. Perfect for weekdays or last-minute gatherings.
Step-by-Step Instructions
Step 1: Prepare the Shortbread Crust
Preheat the oven to 350°F (175°C) and line a 9″x13″ baking pan with parchment paper, letting the edges overhang for easy removal. Cream together the softened butter and powdered sugar until light and fluffy—about 2 minutes. Add vanilla extract.
Gradually add in the flour and salt until a dough forms. Press evenly into the baking pan and bake for 15 minutes or until lightly golden.
✨ Pro Tip: Use the bottom of a measuring cup to press the dough for an ultra-even crust.
Step 2: Make the Rhubarb Filling
While the crust bakes, whisk eggs and granulated sugar in a mixing bowl until smooth and pale. Add flour, cardamom (or cinnamon), and vanilla extract, whisking lightly to combine.
Fold in chopped rhubarb. If your rhubarb is extra tart, sprinkle in 1 extra tablespoon sugar.
Tip: Pre-taste your rhubarb—some varieties are more acidic than others.
Step 3: Pour and Bake
After the crust’s initial bake, pour the rhubarb mixture evenly over the hot crust. Bake for an additional 25–28 minutes, or until the filling is set and just lightly golden on top.
Tip: Give the pan a wiggle. If the center jiggles slightly but edges are firm, you’re spot on.
Step 4: Cool and Slice
Allow the bars to cool in the pan for 30 minutes before transferring them to the fridge to chill for at least 1 hour.
✨ Pro Tip: Cold bars slice more cleanly, making them perfect for presentation.
