Ingredients

Scale

4 large egg whites (room temperature)
1⅓ cups granulated sugar (267 g)
⅓ cup water (79 mL)
¼ teaspoon salt (optional)
¼ teaspoon cream of tartar (0.84 g)
16 ounces (454 g) unsalted butter, room temperature and cut into 1-inch pieces
1 teaspoon pure vanilla extract (optional)

Instructions

1. Separate egg whites from yolks, ensuring no yolk traces remain.
2. Beat egg whites with salt and cream of tartar in a clean stand mixer bowl until soft peaks form, gradually adding ⅓ cup sugar from the total.
3. In a medium pot, combine remaining sugar and water. Cover and bring to boil until sugar fully dissolves, then uncover and boil until syrup reaches 235–240°F (113–116°C).
4. Slowly drizzle hot syrup into whipped egg whites while mixing on low speed, then increase to high speed and whip until meringue cools to room temperature and forms stiff peaks.
5. Switch to paddle attachment and add room temperature butter gradually, one tablespoon at a time, mixing continuously until smooth and creamy. If curdled, keep whipping or chill briefly and re-whip.
6. Add vanilla extract if desired and beat until fully incorporated and light.
7. Optionally add gel food coloring warmed with a small amount of buttercream and fold in for even color.

Notes

🍳 Separate eggs cold but whip whites at room temperature for maximum volume.
🔪 Ensure all bowls and tools are grease-free using lemon juice or vinegar.
