In a saucepan over medium heat, melt butter and stir in brown sugar. Cook for 2 minutes until sugar dissolves and mixture is bubbly.

Slowly add milk while whisking constantly, then bring to a gentle boil. Remove from heat.

Let mixture cool slightly, then whisk in powdered sugar and vanilla until smooth and creamy.

Spread or pipe onto cakes, cupcakes, or cookies while slightly warm for the perfect glossy finish.

Use sifted powdered sugar for the smoothest texture. Add a pinch of sea salt for balance. Frost while slightly warm for glossiness.
