Grapefruit Bars Ingredients
• Get ready to create something special!
For the Crust
- All-Purpose Flour – Provides structure for the crust; you can swap with gluten-free flour if needed.

- Salt – Enhances the overall flavor of the crust; omit if using salted butter.
- Butter (room temperature) – Creates a rich and tender crust; unsalted butter is preferred to control salt content.
For the Filling
- Granulated Sugar – Sweetens the filling; consider coconut sugar for a healthier option.
- All-Purpose Flour (for filling) – Thickens the citrus filling; no substitutions recommended for best results.
- Large Eggs – Provides richness and helps set the filling; egg replacer can be used for a vegan version.
- Grapefruit Zest – Adds intense grapefruit flavor; can replace some with lemon zest for added tang.
- Grapefruit Juice – Creates the filling’s base flavor; mix with lemon juice to enhance tartness.
- Pink Food Coloring – Optional for a vibrant appearance; no substitutions necessary.
Step‑by‑Step Instructions for Grapefruit Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms, prepare an 11×7-inch baking dish by lightly greasing it or lining it with parchment paper. This step ensures easy removal of the grapefruit bars later and sets the stage for a perfectly baked crust.
Step 2: Prepare the Crust
In a mixing bowl, combine all-purpose flour, powdered sugar, salt, and room-temperature butter. Using a pastry cutter or your fingers, blend the ingredients until the mixture resembles coarse crumbs. Once combined, press this crust mixture evenly into the bottom of your prepared baking dish. Bake for 18-20 minutes until golden brown and fragrant, allowing it to firm up while you prepare the filling.
Step 3: Make the Filling
While the crust is baking, whisk together granulated sugar and flour in a separate bowl. Gradually add in the large eggs, grapefruit zest, grapefruit juice, and optional pink food coloring. Stir the mixture until it becomes smooth and well combined, ensuring your filling is both tangy and sweet for those delicious grapefruit bars.
Step 4: Combine and Bake Again
Once the crust is done baking, remove it from the oven and pour the grapefruit filling over the hot crust. Carefully return the dish to the oven and bake for an additional 20 minutes. The filling should set with a slight jiggle in the center; it will continue to firm up as it cools.
Step 5: Cool and Refrigerate
After baking, allow the grapefruit bars to cool completely in the pan for about an hour at room temperature. Once cooled, refrigerate the bars for at least 2 hours. Chilling ensures the filling achieves the perfect texture and allows the flavors to meld beautifully, making every bite a refreshing delight.
Step 6: Cut and Serve
Once chilled, take the pan out of the refrigerator and slice the grapefruit bars into squares or rectangles. For an elegant touch, garnish with extra grapefruit zest or fresh fruit slices before serving. Enjoy these tangy grapefruit bars at your next gathering or as a refreshing treat at home!
