Ingredient Breakdown
Let’s gather all the ingredients you need for these scrumptious grapefruit bars!
- 1 cup Graham Cracker Crumbs
- 1/4 cup Granulated Sugar
- 1/2 cup Unsalted Butter, melted
- 2 large Eggs
- 1 cup Granulated Sugar (for filling)
- 1/4 cup Fresh Grapefruit Juice
- 1 tablespoon Grapefruit Zest
- 1/4 cup All-Purpose Flour
- A pinch of Salt
Let’s Get Cooking!
Step 1: Preparation (10 min)
Start by preheating your oven to 350°F (175°C) and grease a baking dish (about 8×8 inches works well). If you have parchment paper handy, line the dish for easy removal and cleanup later trust me, it helps! The anticipation starts here: you’re going to want to have a taste of what’s to come.
Step 2: Making the Crust (10 min)
In a mixing bowl, combine 1 cup of graham cracker crumbs, 1/4 cup granulated sugar, and 1/2 cup of melted unsalted butter. Mix until it’s all coated and resembles wet sand. Press the mixture evenly into the bottom of the prepared baking dish. You can use your fingers, but I like to use the bottom of a measuring cup to really pack it down, fortifying our base like a boss.
Bake for about 10 minutes, until slightly golden. The smell that fills your kitchen is incredible! You’ll want to hold off on devouring it just yet–the best is yet to come!
Step 3: Making the Filling (10 min)
While the crust is baking, let’s whip up that filling! In a large bowl, whisk together 2 large eggs and 1 cup of granulated sugar until combined and creamy. Add in 1/4 cup of fresh grapefruit juice, 1 tablespoon of grapefruit zest, 1/4 cup of all-purpose flour, and just a pinch of salt. Stir until it’s smooth, no lumps allowed! You want it to be velvety and just waiting to pour over that crust.
Step 4: Pouring It All Together
Once your crust is done and slightly cooled (just a few minutes!), pour that glorious filling over the top. Spread it out evenly; it’ll work its way into your crust while baking, like an eager little helper!
Bake for an additional 15-20 minutes, until the filling is set but still has a slight jiggle (because who doesn’t love a good jiggle?). It should be a beautiful, golden hue, almost like the sun itself.
Step 5: Cooling and Serving (15 min)
Allow the bars to cool in the pan on a wire rack for about 30 minutes, then refrigerate for at least an hour before cutting them. Trust me; they’ll cut cleaner when chilled. Once they’re set, slice them into squares or rectangles, whatever your heart desires! Dust with powdered sugar if you’re feeling fancy, and maybe grab a slice to enjoy right away… or several. I won’t judge!

Serving and Storage Tips
How to Serve This Grapefruit Bars
These bars are absolutely delightful when served cold, but I encourage you to try them warm, too a little scoop of vanilla ice cream never hurt anyone! You can plate them up on a pretty dish and they’ll be your new go-to dessert for dinner parties!
Storage
You can store these Grapefruit Bars covered in the refrigerator for up to four days, but I doubt they’ll last that long!
Reheating Instructions
Though I love them straight from the fridge, if you prefer them warm, just cover them in foil and pop them in a low oven (about 300°F) for 10-15 minutes.
Freezer Friendly?
Yes, you can absolutely freeze these bars! They keep well for about 2 months; just be sure to wrap them tightly in plastic wrap and then foil to prevent freezer burn. Thaw in the fridge overnight before serving.
