Ingredients

Shortbread Crust

1/2 cup butter, softened
1/3 cup granulated sugar
1 teaspoon vanilla extract
2 cups white whole wheat flour

Grapefruit Filling

3/4 cup grapefruit juice
2 tablespoons grated grapefruit zest
5 large eggs
1-1/4 cups granulated sugar
3/4 cup white whole wheat flour
1/2 teaspoon salt
Powdered sugar for dusting

Instructions

Shortbread Crust

Preheat oven to 350F. Line a 9x9 baking pan with parchment paper. Set aside. In a large bowl, beat butter and sugar together with a handheld mixer until completely creamed, about 2 minutes. Fold in vanilla, salt and flour until a dough forms.
Pat dough evenly into the bottom of the prepared pan. Bake at 350F 15-20 minutes or until lightly browned. Remove from oven and cool slightly while you prepare the filling.

Grapefruit Filling

In a large bowl, whisk all filling ingredients until smooth. Pour over crust and bake custard bars at 350F an additional 30-35 minutes until the filling is set (the center may still slightly jiggle)
Cool bars completely on a wire cooling rack then chill completely before dusting with powdered sugar, slicing into squares and serving. Enjoy!
