Common Questions
Is this a buttercream or a cream cheese frosting?
It is a hybrid. You get the fluffy, pipeable feel of buttercream, plus a gentle cream cheese tang. Think “buttercream with a personality.”
What kind of cream cheese should I use?
Use block-style, full-fat cream cheese. Tub or spreadable cream cheese is softer and can make the frosting loose, especially if you are piping.
Can I make it more tangy?
Yes. Add another tablespoon of sour cream or a teaspoon more lemon juice. Add slowly and re-whip. Too much liquid can loosen the texture, so balance with a few tablespoons of powdered sugar if needed.
Can I make it more zesty without adding extra liquid?
Absolutely. Add more lemon zest. Zest brings big citrus flavor without thinning the frosting.
My frosting looks curdled. Did I ruin it?
Probably not. If your butter or cream cheese was too cold, it can look lumpy. Let the bowl sit 10 minutes, then beat again. If it is too warm and looks loose, chill 15 minutes and re-whip.
How do I make it whiter?
Use clear vanilla extract and beat the butter well at the start. A tiny pinch of salt is great, but skip dark vanilla bean paste if you want super white frosting.
How much does this make?
It typically yields about 3 1/2 to 4 cups, depending on how long you whip it. That is enough for 12 to 16 cupcakes (generous swirls) or a 9x13-inch cake. For a 2-layer 8-inch cake, you should have enough for filling and a medium-thick coat. For tall, heavily frosted layers, scale up by 1.5x.
Can I make it ahead?
Yes. Make the frosting up to 5 days ahead and refrigerate. Let it sit at room temperature for 30 to 60 minutes, then re-whip until fluffy.
What about cupcakes or cake that are already frosted?
Once frosted, you can refrigerate cupcakes or cake (covered) for up to 3 days. For the best texture, let slices or cupcakes sit at room temperature for 20 to 30 minutes before serving so the frosting turns creamy again.
How do I make it stiffer or softer?
Stiffer for piping: beat in 1/2 cup powdered sugar (about 60 g) at a time until it holds sharper peaks.
Softer for spreading: beat in 1 teaspoon to 1 tablespoon heavy cream at a time until it swooshes easily.
