Recipe FAQs

Can I use natural peanut butter?

I don’t recommend using natural peanut butter in this recipe. The oil in regular peanut butter helps the frosting to whip up nicely.
If you would like more of the natural peanut butter flavor, you can add a couple of pinches of sea salt to the frosting.
