Ingredients You'll Need
- Butter. Adds a delicious flavor to the frosting. Stick with unsalted butter to control the amount of salt. Allow your butter to sit at room temperature for 30 minutes to 1 hour. It should be malleable without being greasy or melted.
- Banana. Fresh bananas add the best flavor. You’ll want to use very ripe bananas for easy mashing, plus they’ll add a sweet banana flavor.
- Lemon juice. You only need 1 teaspoon of fresh-squeezed lemon juice to prevent the bananas from turning brown. It’ll also balance the sweetness of the ripe bananas and sugar.
- Powdered sugar. Sweetens the frosting and creates a smooth and creamy consistency. Sift your sugar to remove any lumps.
- Vanilla. Always use pure vanilla extract for the best flavor.
Fresh Banana Substitution
We love the flavor that fresh bananas add to this buttercream. However, if you prefer to use banana extract, you can certainly do so. Replace the mashed banana with 1 teaspoon of banana extract. Additionally, you’ll need 1-2 tablespoons of heavy cream and any milk to thin out the frosting to your desired consistency.
Helpful Tools For Making Easy Buttercream Frosting
- Digital kitchen scale or measuring cups. Using a scale will give you the most accurate measurements.
- Measuring spoons.
- Mixer. A handheld or stand mixer will work.
- Small bowl. For mashing the bananas.
- Large bowl. A stand mixer bowl or large mixing bowl will work.
- Rubber spatula.
Buttercream in 3 Simple Steps
Beat the butter. Beat until smooth and creamy.
Add banana and lemon juice. Mix until mostly combined (some chunks of bananas are ok!).
Add sugar and vanilla. Mix the powdered sugar and vanilla with the banana mixture and beat for several minutes until light and fluffy.
How Much Frosting Will This Recipe Make?
This recipe yields 2.5-3 cups of frosting, which is enough to cover 18-24 cupcakes, a 9x13-inch cake, or a two-layer 8-inch or 9-inch cake.
Note: Why the range of frosting? The longer the buttercream whips, the more air is incorporated, resulting in a greater volume. However, if you over whip the frosting, there will be lots of air pockets, and you won’t have a super smooth buttercream.
Tips for Making the Best Buttercream
- Sift the powdered sugar. If your powdered sugar is lumpy, sift it before adding it to the butter to have a smooth and creamy buttercream consistency.
- Use the paddle attachment. The paddle attachment incorporates less air into the frosting than the whisk attachment (otherwise, you will have too many air bubbles!).
- Slowly mix in sugar. Once you add the sugar to the butter, turn the mixer to low speed to prevent the sugar from flying out of the bowl. I cover the mixer with a kitchen towel until the sugar is combined with the butter.
- Mix on low speed. If there are too many air bubbles in your frosting, mix the buttercream on low to eliminate the large air pockets.
What to Serve Banana Buttercream With
There are so many recipes that pair well with banana frosting. Here are some of our favorites:

Storage & Freezing Tips
Buttercream frosting is easy to make and great for prepping ahead. Here are all the ways you can store your banana buttercream:
- At room temperature. Store the buttercream in an airtight container at room temperature for up to 2 days. If it’s a hot day, transfer to the fridge to prevent your buttercream from melting.
- Refrigerator. Store buttercream in the fridge in an airtight container for up to 1 week. Bring to room temperature and re-mix with the paddle attachment before using.
- Freezer. Want to prep ahead? Store the frosting in a resealable freezer-safe bag in the freezer for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature and re-whip before using.
Frequently Asked Questions
Yes, this is pipeable. Depending on how much you mash the bananas, you might have some small chunks in the frosting and will need to cut a slightly larger hole in your disposable pastry bag for piping or use a large round pastry tip to ensure the buttercream easily flows.
Still too thick? Add more mashed bananas, starting with 1 tablespoon at a time, to the buttercream until you have your desired consistency.
If your frosting is too thin, mix in additional sifted powdered sugar until desired consistency. Just note that the more you mix in, the sweeter the mixture will become.
