Grapefruit Bars + Video
Grapefruit Bars are just like your favorite lemon bars with a shortbread crust and citrus curd, but with the sweeter flavor of pink or ruby red grapefruit.
There’s lemon bars and lime bars, so why not grapefruit bars?!
When I originally made this recipe in February 2012, I used ruby red grapefruit. As I tested this recipe again, I realized that it’s not quite as tart as I like my citrus desserts to be.

Types of Grapefruit
Depending on the type of grapefruit used, it may not be as tart as its citrus counterparts (i.e. lemons or limes). You can spike up the tangy flavor by swapping some of the grapefruit juice with lemon juice. (See notes in the recipe card.)
FYI: Pink or white grapefruit is more tart than ruby red grapefruit, which is more sweet. Keep that in mind as you make this recipe. Both will work fine as far as the chemistry goes while baking.
Crust to Filling Ratio
I prefer my citrus bars to have almost equal parts of crust to filling. More like 1/3 crust, and 2/3 filling. The crust is merely to hold that luscious citrus layer, because if I had it my way, I’d eat the curd with a spoon.
The shortbread crust is still good though. A classic and sturdy base for a softer set fruit curd topping. You can always double the crust portion of the recipe if you would like a ratio of equal crust to filling.
A little dusting of powdered sugar on top with a fine mesh sieve is the icing on the cake, and oh so pretty.
Grapefruit Bars
These grapefruit bars are fashioned after the recipes for my lemon and lime bars with just a little more zest and juice. Since grapefruits are naturally more mild, they need just a little extra oomph.
If you’re a citrus fan like I am, I’m sure you will enjoy these pretty pink dessert bars. Happy Baking!
Grapefruit Bars
Ingredients
Crust:
- 1 cup (120 g) all-purpose flour
- ¼ cup (30 g) powdered sugar
- ¼ tsp salt
- ½ cup (113 g) butter, room temperature (cut into 8 pieces)
Filling:
- 1 ½ cups (250 g) granulated sugar
- ¼ cup (30 g) all-purpose flour
- 4 large eggs
- 1 Tablespoon grapefruit zest
- 1 cup (237 ml) grapefruit juice, (or combination or grapefruit + lemon juice*)
- pink food coloring, optional
Instructions
- Preheat oven to 350 degrees Fahrenheit. Lightly grease or line an 11×7-inch baking dish with parchment paper that overhangs 2-inches on both sides. (Do not overdo it on the cooking spray; just a very light coating.)
- CRUST: Combine the flour, powdered sugar, salt, and butter in a food processor or stand mixer. Pulse/mix until mixture resembles fine crumbs that start to clump together. Press onto the bottom of the prepared baking dish. Bake at 350˚F for 18-20 minutes, or until golden brown.
- FILLING: Prepare filling when crust is just about done. Whisk together the sugar and flour in a bowl. Add the eggs, one at a time, whisking well after each addition. Add the zest, juice, and 3 drops or so of food coloring (if desired). Whisk together.
- Pour filling over HOT crust and bake an additional 20 minutes or until filling no longer jiggles, and edges brown.
- Let cool completely in the pan, about 1 hour. Then refrigerate for at least 1-2 hours until cold. Lift bars out of pan with parchment paper for easy cutting and serving. Store leftovers in the refrigerator.

Notes
- NOTE: Grapefruits are a very mild citrus fruit compared to tangy lemons or limes. Consider using 3/4 cup of grapefruit juice and 1/4 cup lemon juice to help boost the flavor and/or use more zest (up to 1 Tbsp more).
- FYI: Pink or White Grapefruit is more tart than Ruby Red Grapefruit
- This can be made in a 9×9-inch square baking dish, but would be best made with less filling. The crust measurements can remain the same.
- To reduce the filling for a 9×9-inch pan, I would do: 1 cup granulated sugar, 3 Tbsp all-purpose flour, 3 large eggs, 2 tsp grapefruit zest, and 2/3 cup grapefruit juice.
- This recipe can be made in a 13×9-inch pan, but you may want to 1.5x the crust recipe, or the crust will be very thin.

Oh man I have totally missed an (I think?) important point in this recipe, you should pour the filling in while the crust is hot!
I’m making this recipe for a big celebration and so I made the crust yesterday and the filling today. The crust was therefor cold. It took the bars a lot longer to set because of that, closer to 30-45 minutes. The top is completely discoloured 🙁 I was sooo looking forward to these beautifully pink bars.
However the taste is still amazing!
I will definitely try this recipe again, the taste is great and the recipe itself is quite uncomplicated. But going through the comments it doesn’t seem that anyone else made my mistake, I would add this pointer to the notes just to warn future bakers 😉
Thank you for the recipe!
Hi Ru, if you read carefully all the information is there to prepare the filling when the crust is just about done and to pour the filling over the hot crust. I will go ahead and uppercase the hot part so it doesn’t get overlooked by others. Glad it was still tasty!
My favorite part of the summer is teaching my grandkids how to bake. I trade off teaching them something our family has made for years, and us trying a new recipe that they think would taste good. One of my granddaughters sent me this recipe among a bunch of others, we’re so excited to try it! I even got new countertops installed over the winter so we’d all have more room to bake together. Thank you for helping me with this special tradition!
i really would like to try this recipe, but i dont have an oven. have you (or anyone) had any luck using an instant pot or ninja foodi?
also, i always have alot of canned grapefruit segments on hand. is it possible to substitute them into the recipe at all?
Unfortunately, this recipe would require an oven and I’m not sure that substitute would work. Sorry!
Please adjust the recipe not just the notes! I wasted a ton of ingredients and time using the original recipe in a smaller pan as it was suggested in the recipe. I baked for 40 minutes and the filling never set. If I had to give this stars I would give it 0.
Sounds like you chose to use a different pan than stated. The recipe is clearly written for an 11×7-inch pan. The notes are there if you need help adjusting the recipe with a different size pan and I’ve included that information for those who don’t have the correct size pan. I’m sorry, but it sounds like you should have read every note before starting the recipe if you chose to use a different size pan.
I would be SO great if you would write the measuring units in grams .. because in Denmark we dont use cups.
I get it, but that’s what we use here in the US. You’ll have to use a converting chart/calculator, sorry!
These bars are just perfect! My husband and I are really enjoying them.
Wonderful! Thanks for your comment Deanna!
