The Story Behind Italian Buttercream
How to Make Italian Buttercream
Follow our traditional Roman technique for perfect results
Ingredients
- 21 tablespoons unsalted butter, softened
- 1 teaspoon pure vanilla extract
- 1 cup plus 1 teaspoon granulated sugar (divided)
- 2 teaspoons light corn syrup
- 1/4 cup water
- 3 large egg whites, at room temperature
- Pinch of salt
The Preparation
- **Prepare the egg whites:** In the clean, grease-free bowl of a stand mixer fitted with the whisk attachment, whisk the egg whites on medium-high speed until soft, billowy peaks form. Set aside.
- **Make the sugar syrup:** In a small, heavy-bottomed saucepan, combine 1 cup of granulated sugar, the corn syrup, and 1/4 cup water. Heat over medium-high heat, stirring gently only until the sugar dissolves. Once dissolved, stop stirring. Continue to cook until the syrup reaches 240°F (115°C) on a candy thermometer. This is the soft-ball stage.
- **Combine syrup and egg whites:** With the mixer still running on medium-high speed, slowly and very carefully pour the hot sugar syrup in a thin, steady stream down the side of the bowl into the whipped egg whites. Be careful to avoid pouring directly onto the whisk. Continue whipping the meringue on high speed until it is glossy, thick, and has completely cooled to room temperature (the outside of the bowl should no longer feel warm to the touch). This step can take 10-15 minutes.
- **Add butter:** Reduce the mixer speed to low. Begin adding the softened butter, one tablespoon at a time, allowing each piece to fully incorporate before adding the next. The mixture may look curdled or soupy at this stage; this is normal. Continue mixing, and it will eventually come together into a smooth, fluffy buttercream.
- **Finish with vanilla:** Once all the butter is incorporated and the buttercream is smooth and light, add the pure vanilla extract and mix on low speed until just combined.
- **Use or store:** Your silky Italian buttercream is now perfectly ready to use for frosting cakes, cupcakes, filling macarons, or piping decorative elements onto your favorite Italian pastries.
Expert Tips for Best Results
Achieving a smooth, stable buttercream requires patience. If it looks curdled after adding butter, continue mixing on medium speed. The emulsion will eventually come together into a velvety consistency. Ensure your butter is truly softened, but not melted, for the best result.
For an extra layer of elegance, consider infusing your buttercream with citrus zest (lemon or orange) or a delicate liqueur like Amaretto or Limoncello. Add these at the very end, after the vanilla, to preserve their delicate notes.
Italian buttercream can be stored at room temperature for up to 2 days, in the refrigerator for up to 2 weeks, or frozen for up to 3 months. If chilled or frozen, bring to room temperature and re-whip briefly until smooth before using.

Frequently Asked Questions
Is this recipe authentic?
Absolutely. This recipe adheres to the classic Italian method for buttercream, where a hot sugar syrup is slowly incorporated into whipped egg whites. This technique, a hallmark of traditional Italian pasticceria, ensures a remarkably stable, less sweet, and exceptionally smooth frosting, upholding Gustoli’s commitment to culinary authenticity.
Can I make it ahead?
Yes, Italian buttercream is excellent for making ahead! Store it in an airtight container in the refrigerator for up to two weeks, or freeze it for up to three months. Before using, simply bring it to room temperature and re-whip it in your stand mixer until it regains its light, fluffy consistency.
Is it healthy?
As a rich dessert component, Italian buttercream is best enjoyed as an occasional treat rather than a daily staple. However, unlike some frosting types, it uses real butter and egg whites, without excessive artificial ingredients. Its stability and less-sweet profile encourage smaller, more satisfying portions, fitting within a balanced Mediterranean approach to enjoyment.
