Tips for making creamy peanut butter frosting
- Use room temperature butter because it whips more easily and produces a fluffier frosting
- Whip it! Want fluffy frosting? Whipping is the key!
- Use creamy peanut butter. I don’t recommend using natural peanut butter.
Is peanut butter frosting gluten free?
Yes!!
Does peanut butter frosting need to be refrigerated? How long does frosting keep?
You can store frosting in a sealed container on the counter for up to 2 days.
However, you can store frosting in a sealed container in the fridge for up to 1 week. Before using, place the frosting on the counter and allow it to come to room temperature. Give it a quick whip with an electric mixer before using.
Why do I have air bubbles in my frosting and how can I get rid of them?
Air bubbles form when whipping the frosting, which is a necessary step in making buttercream! But you can reduce the amount of air bubbles by beating the frosting on low speed for a minute or by hand mixing the frosting. You are essentially pushing out the air bubbles.

It’s 2 to 3 cups of powdered sugar, depending on how sweet you want the frosting.

Seriously delicious. Light, fluffy, sweet and peanut buttery without that cloying dry mouth feel.

Can you add regular vanilla instead of the extract ?
Are you talking about vanilla bean?
