Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the crust:
2.5 cups all-purpose flour
1 cup granulated sugar
1 cup unsalted butter, softened
For the orange filling:
4 large eggs
2 cups granulated sugar
0.5 cup all-purpose flour
0.5 cup fresh orange juice
2 tablespoons orange zest, from about 2 oranges
1 teaspoon vanilla extract
Directions
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan so the bars release easily after baking.
In a large mixing bowl, combine the 2.5 cups all-purpose flour, 1 cup granulated sugar, and 1 cup softened unsalted butter. Mix until the texture resembles coarse crumbs. Press this mixture evenly into the bottom of the prepared pan to form the crust.
Bake the crust for 15 to 20 minutes, or until it is lightly golden around the edges. Remove it from the oven and let it cool slightly while you prepare the filling.
In a separate bowl, whisk together the 4 large eggs and 2 cups granulated sugar until smooth and well blended. Add the 0.5 cup all-purpose flour gradually, whisking until no lumps remain.
Stir in the 0.5 cup fresh orange juice, 2 tablespoons orange zest, and 1 teaspoon vanilla extract. Mix until the filling is completely smooth.
Pour the orange filling evenly over the slightly cooled crust. Return the pan to the oven and bake for 30 to 35 minutes, or until the filling is set and lightly golden. A toothpick inserted near the center should come out clean.
Remove the pan from the oven and allow the bars to cool completely on a wire rack. Once cooled, slice into squares and serve.
These bars are perfect for serving at brunch, as a light dessert, or as a make-ahead sweet treat for gatherings.
Variations
For a slightly deeper citrus flavor, add an extra teaspoon of orange zest to the filling. If you enjoy a more balanced sweet-tart profile, stir in 1 to 2 tablespoons of lemon juice along with the orange juice. A dusting of powdered sugar over the cooled bars gives them a simple bakery-style finish.
You can also change the texture by using a shortbread-style crust. To do that, chill the crust for 10 minutes before baking for a slightly firmer base. For a softer, more dessert-like finish, serve the bars chilled straight from the refrigerator.
Another nice variation is to add a light orange glaze made from powdered sugar and orange juice after the bars have cooled. This gives them an extra burst of citrus and a more polished look for parties or holiday trays.
Storage/Reheating
Store orange bars in an airtight container at room temperature for up to 2 days. For longer storage, keep them in the refrigerator for up to 5 days. If stacking them, place parchment paper between layers to prevent sticking.
These bars are usually best served chilled or at room temperature, so reheating is not necessary. If you prefer a slightly warmer texture, let a refrigerated bar sit out for 15 to 20 minutes before serving. You can also freeze them for up to 2 months. Wrap individual pieces tightly, then thaw them overnight in the refrigerator before enjoying.
FAQs
Can I use bottled orange juice instead of fresh orange juice?
Yes, you can, but fresh orange juice gives the bars a brighter and more natural citrus flavor. Bottled juice works in a pinch, though the final taste may be slightly less vibrant.
Can I make orange bars ahead of time?
Yes. Orange bars are excellent for making ahead because they slice more neatly after cooling. You can bake them a day in advance and store them covered in the refrigerator.
Why did my filling turn out runny?
A runny filling usually means the bars needed a little more baking time or were cut before cooling completely. The filling continues to set as it cools, so patience is important.
Can I freeze orange bars?
Yes. Once fully cooled, cut the bars into squares and wrap them well. Freeze for up to 2 months and thaw in the refrigerator before serving.
Do I need to line the pan with parchment paper?
It is not required, but it helps a lot with easy removal and cleaner slices. Greasing and flouring the pan also works well if parchment is not available.
Can I reduce the sugar?
You can reduce the sugar slightly, but keep in mind that sugar affects both sweetness and texture. A small reduction will work, though the bars may taste a bit more tart.
What kind of oranges work best?
Sweet, juicy oranges such as navel oranges work very well in this recipe. They provide good flavor and enough juice for the filling.
How do I know when the bars are done baking?
The filling should look set and lightly golden, and a toothpick inserted near the center should come out clean. The center should not look wet or overly jiggly.
Can I add a topping?
Yes. Powdered sugar, a simple orange glaze, or even a little extra orange zest on top are all great finishing touches.
Are orange bars served cold or at room temperature?
They are delicious both ways. Chilled bars have a firmer texture, while room-temperature bars feel a bit softer and more delicate.
