• Grapefruit Zest – Imparts citrus flavor and aroma; fresh zest is best for vibrant taste.

Step‑by‑Step Instructions for Grapefruit Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Meanwhile, prepare an 11×7-inch baking dish by lining it with parchment paper or lightly greasing it with baking spray. This ensures your delightful Grapefruit Bars will release easily once baked and cooled.
Step 2: Prepare the Crust
In a food processor, combine all-purpose flour, powdered sugar, salt, and cold butter cut into cubes. Pulse until the mixture resembles coarse crumbs, about 30 seconds. Press this crumbly dough evenly into the bottom of your prepared baking dish, then bake for 18–20 minutes or until golden brown on the edges, creating the perfect base for your bars.
Step 3: Make the Filling
While the crust bakes, whisk together granulated sugar and a tablespoon of flour in a large mixing bowl. Carefully add the eggs one at a time, whisking thoroughly after each addition until smooth. Then, mix in the grapefruit zest and juice, stirring until fully combined. This filling will add a burst of citrusy flavor to your Grapefruit Bars.
Step 4: Bake the Bars
Once your crust is golden, remove it from the oven and immediately pour the grapefruit filling over the hot crust. Spread the filling evenly and return the baking dish to the oven. Bake for an additional 20 minutes, or until the filling is set and lightly browned at the edges, ensuring a creamy yet firm texture.
Step 5: Cool and Chill
After baking, allow the Grapefruit Bars to cool on a wire rack for about 1 hour at room temperature. Once they have cooled, transfer the dish to the refrigerator and chill for at least 2 hours. This step enhances the flavor and texture, making your bars even more delectable when served.
Step 6: Cut and Serve
Once chilled, carefully remove the Grapefruit Bars from the baking dish using the parchment paper. Place them on a cutting board, and with a sharp knife, cut them into neat squares or rectangles. For an extra touch, dust powdered sugar over the top before serving, or add fresh grapefruit slices for a beautiful garnish.

Grapefruit Bars Recipe FAQs
What type of grapefruit is best for the bars?
Absolutely! When selecting grapefruits, opt for pink or ruby red varieties for a sweeter flavor and vibrant color. Look for fruits that feel firm and heavy for their size, as this indicates juiciness. Avoid grapefruits with dark spots or blemishes, which can suggest overripeness.
How should I store leftover Grapefruit Bars?
To keep your Grapefruit Bars fresh, store them in an airtight container in the refrigerator for up to 1 week. Make sure they are covered to prevent them from drying out. For a delightful chilled treat, serve them straight from the fridge, or allow them to sit for a few minutes for a softer texture!
Can I freeze Grapefruit Bars for later?
Yes! For long-term storage, wrap each bar tightly in plastic wrap, then place them in a freezer-safe container or a resealable plastic bag. They can be frozen for up to 2 months. When you’re ready to enjoy them, thaw the bars in the refrigerator overnight for the best flavor and texture.
What can I use if I have an egg allergy?
Very! If you’re looking for an egg substitute for the filling, you can use 1/4 cup of unsweetened applesauce per egg, or try a commercial egg replacer. This will help maintain the airiness and structure of your delicious Grapefruit Bars while keeping them allergy-friendly!
Why is my filling runny after baking?
Good question! If your filling is runny, it could be due to not baking it long enough. Ensure the filling is set and doesn’t jiggle in the center before removing it from the oven. If it hasn’t set, return it to the oven for a few extra minutes until it firms up nicely.
Is there a gluten-free option for the crust?
Absolutely! You can substitute all-purpose flour with almond flour for a gluten-free crust. Just keep in mind that the texture may be slightly different, but it will still be delicious! Enjoy your baking adventure!
