Hazelnut Praline Buttercream - Master Chefs

This is a proper French-style buttercream (creme au beurre) built on an egg yolk custard base and enriched with hazelnut praline paste. It’s the kind of frosting you’ll find in high-end patisseries, silky and rich with a deep nutty flavor that no American-style powdered sugar buttercream can touch.

The custard base is where all the technique lives. Beat the yolks with sugar until the mixture turns pale yellow and falls in a thick ribbon from the beaters, about seven minutes. Stream in hot milk slowly while beating constantly so the yolks temper gradually instead of scrambling into sweet omelet bits.

Cook the custard briefly over low heat, just 30 seconds, then pour it immediately into a bowl set over ice water. Speed matters here. Every extra second on the heat risks curdling.

Once the custard is completely cool, beat it into softened butter and praline paste. The butter must be at true room temperature, soft enough to leave a fingerprint but not melted or greasy.

Pro Tips

• Have the ice bath ready before you start cooking the custard so there’s zero delay
• Beat the yolk-sugar mixture the full 7 minutes for proper ribbon stage, don’t shortcut this
• If the buttercream looks curdled after adding custard, keep beating. It will come together
• Praline paste can be found at specialty baking stores or made at home from caramelized hazelnuts

Variations

• Swap hazelnut praline paste for almond praline paste for a different nut flavor
• Add a tablespoon of dark rum or Frangelico for a boozy finish
• Use this as a filling between cake layers, inside eclairs, or piped onto cupcakes
