Lighter Orange Bars


Lemon bars, indulgent, tangy and delicious. Everything a lemon flavoured dessert should be.

Lemon bars are quite deceptive. Seemingly healthy, they hide the cupfuls of butter and sugar beneath a delicious tangy taste. In addition to the sugar and fat levels, the amount of lemon filling can be disappointing. I like my lemon bars with thick lemony goodness spread over a delicious crust.

Orange bars are an extension of lemon bars and just as good. Zesty, fresh and fruity, they will not disappoint. These orange bars are fairly simple to make and have just the right amount of filling on top of a delicious crust. They are low in calories with just 111 calories for one bar!


One important note before making these, make sure that you strain your juice before mixing it with the eggs and sugar. Otherwise you will get a lumpy custard and it won’t be pleasant.

Trust me, I tried making different variations of these bars before I finally decided to strain the juice and they magically worked.

These bars start with a reduced calorie base which you crumble on top of a greased baking pan.

Then bake them and make the filling while you wait. You can replace the sweetener in this with an equivalent amount of Stevia or xylitol, but the calories will increase and change depending on your substitutions.

Finally, pour the orange topping on and bake. After baking allow these to cool down in the fridge for at least 3 hours to allow them to set and boom! You have awesome orange bars to savor and enjoy for a few days. Well you might, but these didn’t last very long in my house.

Recipe Notes

You can make oat flour by grinding porridge oats in a blender or food processor. If not using oats, use roughly 90g of plain flour for the crust and adjust the liquid so it looks like  coarse crumbs, but not a kneadable dough.

You can adjust the sweetener to your liking here and can substitute Stevia or sugar in place of sweetener, but the nutritional information may change as a result.

Please make sure to strain the orange juice beforehand as otherwise your custard will separate and be lumpy. For a richer, more custard like version of this recipe, omit the cornstarch and use 2 eggs and 2 egg yolks instead of this and reduce the liquid slightly.
