Description

A sunny twist on the classic lemon bar. These orange squares feature a crisp, buttery shortbread base topped with a luscious, zesty orange custard, perfectly balancing sweetness with bright citrus notes for a refreshing dessert.


Ingredients

Scale

For the Shortbread Crust

  • 1 cup flour (120g), 1/4 cup powdered sugar (30g)
  • 1/4 tsp salt, 1/2 cup cold unsalted butter (113g)

For the Orange Filling

  • 1 1/4 cups sugar (250g), 1/4 cup flour (30g)
  • 4 large eggs, 1 tbsp orange zest
  • 2/3 cup fresh orange juice (159ml), optional coloring

Instructions

Crust: Preheat oven to 350°F. Pulse flour, powdered sugar, salt, and cold butter until fine crumbs form. Press into an 11×7 dish and bake 18–20 mins.

Filling: Whisk sugar and flour. Add eggs one at a time, then stir in zest and juice.

Bake: Pour filling over hot crust; bake another 20 mins until set.

Cool: Cool 1 hour at room temperature, then refrigerate 1–2 hours. Dust with powdered sugar before slicing.

Notes

Zest Before Juice: Always zest oranges while they are whole and firm for better control.

Cold Butter is Key: Cold butter creates steam pockets during baking, resulting in a crisp, flaky shortbread base.

Pro Tip: Chill overnight to allow the citrus oils in the zest to fully infuse the custard for maximum flavor.
