A rich, silky buttercream made with egg yolks, butter, and Italian meringue. Perfect for frosting cakes, cupcakes, or as a versatile base for flavors.
When it comes to cake decorating and filling pastries, nothing beats a silky buttercream frosting that glides like velvet and tastes rich without being overly sweet. This recipe combines the best of both worlds: a custard base made with egg yolks and sugar, enriched with butter, and lightened with a touch of Italian meringue. The result? A luscious, pipeable buttercream that holds shape beautifully and melts in your mouth. 💛
Unlike standard American buttercream, which can sometimes feel heavy or overly sugary, this version is refined and French-inspired. The egg yolk custard gives depth and smoothness, while the Italian meringue balances it with airiness. Together, they create the perfect balance—ideal for cakes, cupcakes, macarons, and entremets. 🎂
You’ll also love how versatile it is—vanilla, almond, citrus, coffee, or even floral extracts can be added to suit any dessert.
Warm the milk with sugar, then temper it into whisked yolks. Cook until the mixture coats the back of a spoon at 181°F (83°C). Strain and cool—this will be the rich base of your buttercream.
Beat softened butter until smooth, then blend in the cooled custard. Finally, fold in Italian meringue for that silky, airy finish. If the mixture seizes, gently warm the bowl over a bain-marie.
From vanilla extract to orange flower water or even coffee, this buttercream welcomes any twist. Use immediately for spreading and piping, or store in the fridge (3 days) or freezer (3 months).
This silky buttercream is more than just frosting—it’s a foundation for creativity in the kitchen. Whether you’re baking for a birthday, a wedding, or a simple weekend indulgence, it’s the finishing touch your desserts deserve. ✨

Pour milk into a saucepan, whisk in half the sugar, and bring to a boil. Stir until sugar dissolves, then cool to 176°F (80°C).
Whisk egg yolks with remaining sugar until pale and thick. Slowly add one-quarter of the hot milk while whisking.
Return mixture to saucepan and cook over low heat, stirring in figure-eight motions until custard reaches 181°F (83°C) and coats a spoon.
Strain custard through a fine sieve into a bowl and whisk until cooled.
In a clean mixer bowl, beat butter until smooth and softened.
Gradually add the cooled custard and beat until combined.
Mix in the Italian meringue until smooth. If too cold, gently warm the bowl in a bain-marie.
