Different Types of Buttercream

Swiss Meringue Buttercream Ingredients
- 5 Large Egg Whites – Forms the base of the buttercream. Ensure eggs are at room temperature.
- 1½ Cups (300g) Granulated Sugar – Dissolved into the egg whites for a smooth consistency.
- 2 Sticks (225g) Unsalted Butter – Adds richness and creates the creamy texture. Use room-temperature butter.
- 1-2 tsp Vanilla Essence – Enhances flavor. You can substitute with other extracts or citrus zest.
How to Make Swiss Meringue Buttercream
- Prepare the Meringue:
- Separate 5 egg whites into a heatproof bowl. Save the yolks for another recipe.
- Add sugar to the bowl and place it over a saucepan with simmering water (double boiler method).
- Whisk continuously until the sugar dissolves and the mixture reaches 160°F (72°C). Rub a bit between your fingers; it should feel smooth.
- Whip the Meringue:
- Transfer the mixture to a stand mixer fitted with a whisk attachment.
- Beat on medium-high speed for about 10 minutes until stiff peaks form and the bowl no longer feels warm to the touch.
- Incorporate the Butter:
- Reduce speed to low and add butter, one tablespoon at a time.
- Continue mixing until the butter is fully incorporated and the buttercream becomes smooth and fluffy.
- Add Flavoring:
- Mix in vanilla essence or your preferred flavoring.
- Scrape down the sides of the bowl and mix for another minute to ensure even consistency.
Troubleshooting Tips
- Buttercream is soupy? The butter was too warm. Place the bowl in the fridge for 15 minutes and whip again.
- Buttercream is curdled? Keep whipping! It will eventually become smooth.
- Too stiff? Add a small amount of room-temperature butter and mix.
