Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the crust:

• ½ cup unsalted butter, softened
• 1 cup all-purpose flour
• ¼ cup confectioners powdered sugar
• ¼ teaspoon salt

For the filling:

• 1 cup freshly squeezed pink grapefruit juice
• 1 tablespoon grapefruit zest
• 2–3 drops pink food coloring (optional)

Directions

1. Preheat your oven to 350°F (175°C). Line an 8×10-inch baking dish with parchment paper for easy removal.
2. In a medium bowl, combine the softened butter, flour, powdered sugar, and salt. Mix using a fork, pastry cutter, or your hands until the mixture becomes crumbly.
3. Press the crust mixture evenly into the bottom of the prepared baking dish. Bake for 18–20 minutes until lightly golden.
4. While the crust bakes, prepare the filling. In a large bowl, whisk together the sugar and flour.
5. Add the eggs and whisk until smooth. Pour in the grapefruit juice and grapefruit zest. Add a few drops of pink food coloring if desired for a brighter pink appearance.
6. Once the crust is finished baking, carefully pour the filling over the hot crust.
7. Return the pan to the oven and bake for 20–25 minutes, or until the center is set and no longer jiggles.
8. Remove the bars from the oven and allow them to cool at room temperature for about 1 hour.
9. Refrigerate for at least 2 hours to fully set the filling.
10. Lift the bars from the pan using the parchment paper, slice into squares, and dust with powdered sugar before serving.

Storage/Reheating

Store leftover grapefruit bars in an airtight container in the refrigerator for up to 3 days. The bars taste best when chilled because the filling stays firm and refreshing.

If stacking the bars, place parchment paper between layers to prevent sticking.

These bars are not typically reheated since they are meant to be served cold or slightly chilled. However, you can let them sit at room temperature for 10 minutes before serving if you prefer a softer texture.

You can also freeze the bars for up to 2 months. Wrap them tightly in plastic wrap and store them in a freezer-safe container. Thaw overnight in the refrigerator before serving.
