Peppermint is a holiday classic: bright, bold, and unmistakably seasonal. If you love that cool, minty note on everything from cupcakes to cake pops, this frosting delivers without being overpowering.

Key Ingredients

• Unsalted butter – Provides richness and a soft, spreadable texture. Use room-temperature butter for best results.
• Powdered sugar – Keeps the frosting silky and smooth without any graininess.
• Heavy cream – Adds richness and gives the buttercream the right consistency; it won’t thin the frosting like milk can.
• Peppermint extract – Very concentrated; start with a small amount (¼ teaspoon) and adjust to taste.
• Peppermint candies – Optional garnish. Crushed peppermints add a pleasant crunch and festive look.

How to Make Peppermint Buttercream

This frosting is quick and straightforward to prepare.

• Cream the butter. Make sure the butter is soft but not melted. Beat it for about 2 minutes on medium speed until it becomes lighter in color and fluffy.

• Add the remaining ingredients. Add the powdered sugar, peppermint extract, and heavy cream.
• Beat again for 2–3 minutes. This step whips air into the frosting so it’s light and not overly dense or cloyingly sweet.

• Taste and adjust. Try a small taste to check the peppermint intensity and sweetness. Add another 1/4 cup powdered sugar if you prefer it sweeter, or a touch more extract (sparingly) for stronger mint flavor.

Recipe Tips

• Room-temperature butter. It should be soft enough to press with your thumb but not greasy or melted. If needed, soften in 5-second microwave increments.
• Measure the peppermint extract carefully. Peppermint extract is potent; 1/8 to 1/4 teaspoon is usually enough. Add gradually to avoid an overly strong flavor.
• Adjust sweetness with powdered sugar. This recipe works well with about 2 cups of powdered sugar. Increase by 1/4 cup for a sweeter frosting or decrease slightly for less sweetness.

Storage Tips

You can refrigerate or freeze leftover buttercream so none of it goes to waste.

• Store in an airtight container in the refrigerator for up to 7 days. Bring to room temperature for about an hour, then rewhip to restore a spreadable texture.
• Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the fridge, then let sit at room temperature and rewhip before using.

Peppermint Candies

Crushed peppermint candies make a festive garnish and add a pleasant crunch.

• Place peppermints in a zip-top bag and remove the air.
• Crush with a rolling pin, meat mallet, or heavy pan until they’re in small pieces.
• Sprinkle over frosted cupcakes, cookies, or bars.

Ways to Use Peppermint Frosting

This buttercream can be used anywhere you’d use a classic buttercream. A few favorite uses:

Buttercream Variations

• For a lighter frosting, substitute half the heavy cream with milk, but expect a slightly thinner consistency.
