What Is Buttercream?
Buttercream is a type of frosting that's a mixture of sugar and fat. Traditionally, buttercream is known for having a light and smooth texture.
A good buttercream, like this macaron filling, is not too sweet. It has the perfect balance of butter and sugar.
This recipe is an American-style buttercream that's made with butter as the fat source as well as confectioners' sugar.
Ingredients You Need
Here are the ingredients you'll need to make vanilla macaron buttercream:
- Unsalted butter: Before making the vanilla buttercream, allow the butter to soften to room temperature. If you're using salted butter, be sure to adjust the amount of added salt.
- Confectioners' sugar: Sifting the confectioners' sugar will help you achieve a light and smooth buttercream. First measure the confectioners' sugar, then sift.
- Heavy cream: This ingredient helps thin out the buttercream. Make sure your heavy cream is as fresh as possible so your buttercream will last up to 1 month after preparing it.
- Vanilla bean paste: This is my secret ingredient for the buttercream filling. Since vanilla beans can be very pricey, we're opting for vanilla bean paste. The paste is cheaper and still gives us beautiful vanilla seed specks throughout the buttercream.
- Fine sea salt: Salt is an important ingredient that helps balance out the sweetness of the buttercream.

How To Make This Recipe
1. The first step is the beat the butter until it's light and fluffy, which usually takes about 2 - 3 minutes. Remember to scrape down the side of the mixer bowl as needed so all of the butter is evenly creamed.
2. Slowly add confectioners' sugar to the butter, ½ cup at a time. Allow the sugar to incorporate with the butter. During this step, I like to leave the mixer on medium-low speed so the confectioners' sugar doesn't explode everywhere.
3. Next, it's time to thin out the buttercream with some heavy cream, as well as add in flavoring with vanilla bean paste and fine sea salt.
4. Beat the buttercream on medium-high speed for a full 5 minutes. This will give the buttercream a light and fluffy texture.
5. In order to smoothly pipe the buttercream, it's important to deflate it using a silicone spatula. Press the buttercream around the side of the mixer bowl until most of the air bubbles have been pushed out.
- Vanilla buttercream filling can be stored in an airtight container in the refrigerator for up to 1 month, as long as your heavy cream is fresh. Allow the buttercream to come to room temperature before piping on the macarons.
- In order to achieve a light and pillowy buttercream, beat for a full 5 minutes after all of the ingredients have been incorporated. Don't be tempted to cut this time short if you want an airy texture.
- Don't forget to mature the macarons with the buttercream filling in the refrigerator overnight. This will allow the macarons to slightly soften and develop a deeper flavor. The macarons will last for 7 days in an airtight container in the refrigerator.
- Filled macarons can be stored in the freezer for up to 1 - 2 months. Learn more about how to properly store macarons.
