Orange Lemon Frosting

This citrus frosting gets its punch from real orange and lemon zest creamed directly into the butter, so every spread is loaded with fragrant citrus oil. Fresh orange and lemon juice go in too, giving it a genuine tang that powdered mixes can’t touch.

The egg whites are the interesting part here. They go in unbeaten, blended with the butter and zest before the powdered sugar. This gives the frosting a lighter, silkier texture than a standard American buttercream while keeping it sturdy enough to spread and hold its shape on a cake.

Add the sugar and juice alternately, a bit at a time. Too much liquid at once thins it out and you’ll need more sugar to recover. Too much sugar without liquid makes it stiff and crumbly. The goal is a smooth, spreadable consistency that holds a swirl but isn’t so thick it tears the cake surface.

Chef Tips

• Sift your powdered sugar. Even a few lumps will show up as gritty spots in the finished frosting.
• Zest first, then juice. It’s much easier to zest a whole fruit than one you’ve already cut in half.
• Start with room temperature butter. Cold butter won’t cream smoothly with the zest and you’ll get an uneven texture.
• A tiny amount of orange food coloring sells the citrus look, but it’s purely optional.

Variations

• Lemon-forward: Double the lemon zest and skip the orange for a pure lemon buttercream.
• Cream cheese citrus: Replace half the butter with softened cream cheese for a tangier, denser frosting.
