Tips for Perfect Coffee Buttercream 🔑

Step-by-Step Flavor Magic 👩🍳
1. Brew a Coffee Syrup
Start by making a dry caramel with sugar until golden amber, then deglaze with hot water and whisk in freshly ground coffee. This syrup chills overnight, developing a bold, smooth coffee essence.
2. Whip the Italian Meringue
Heat sugar and water to 121°C (250°F) while whipping egg whites to peaks. Slowly drizzle the syrup into the whites, whisking until glossy and cool. This forms the airy base for your buttercream.
3. Blend It All Together
Beat butter until silky smooth, then add the rich coffee syrup. Slowly fold in the meringue until you have a luscious, coffee-infused buttercream ready to pipe or spread.
Serving Ideas ☕🍫
- Frost a classic mocha cake for a bakery-worthy finish.
- Pipe onto cupcakes for a coffee shop vibe at home.
- Use as a macaron filling with a touch of cocoa for mocha macarons.
- Spread between biscuit layers for a French-inspired entremet.
