Essential Ingredients

Here’s what you’ll need to make this delicious dish:

Grapefruits: Fresh grapefruits provide a bright zing; choose ones that feel heavy for their size.
Sugar: Granulated sugar balances the tartness of grapefruits beautifully; don’t skimp here.
Butter: Unsalted butter creates a rich base; always use fresh butter for the best flavor.
Eggs: Large eggs add richness and help set the bars; room temperature works best.
All-Purpose Flour: This forms the structure of our bars; sift it to avoid lumps.
Baking Powder: A little leavening agent helps the bars rise slightly; ensure it’s fresh for optimal results.
Powdered Sugar: For dusting on top; it adds an elegant finish and sweetness.

The full ingredients list, including measurements, is provided in the recipe card directly below.

Let’s Make it together

Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Grab an 8×8-inch baking pan and line it with parchment paper for easy cleanup.

Make the Crust: In a mixing bowl, combine softened butter and granulated sugar until creamy. Add in flour and a pinch of salt until crumbly. Press this mixture evenly into your prepared pan.

Prepare the Filling: In another bowl, whisk together freshly squeezed grapefruit juice and zest with eggs and sugar until frothy. Mix in flour and baking powder until smooth—no lumps allowed!

Combine Everything Together: Pour that luscious grapefruit mixture over your crust. Use a spatula to spread it evenly so every bite gets that tangy goodness.

Bake to Perfection: Place your pan in the preheated oven for about 20-25 minutes or until set but slightly jiggly in the center. Keep an eye on it; we want these bars tender but not overbaked.

Cool & Dust with Sugar: Once baked, let the bars cool completely in the pan before lifting them out using parchment paper. Dust with powdered sugar right before serving—because who doesn’t love a little extra sweetness?

And there you have it! Irresistible Grapefruit Bars: Sweet-Tart Citrus Delight are ready to wow your guests—or indulge yourself with a slice (or two). Enjoy!
