Recipe Questions

Can I make this frosting ahead of time?

Even if it's better to make it at the last minute, it's possible to prepare it in advance and keep it in the fridge for up to 2 days or whip it until you get soft peaks, then give it a boost before using it until stiff peaks.

Can I freeze this frosting?

While the frosted cakes can be frozen, the frosting itself does not freeze well. Its texture may become grainy after thawing.

Can I adjust the lemon flavor in the frosting?

Yes, you can adjust the lemon flavor by adding more or less lemon curd or lemon juice according to your preference.

Can I substitute mascarpone cheese with cream cheese?

While mascarpone cheese provides a unique flavor and texture, you can substitute it with cream cheese for a slightly different taste.

Can I color this frosting?
