1-First, gather your ingredients: 1 cup packed brown sugar, 1/2 cup cubed butter, 1/4 cup milk, 2 1/2 cups powdered sugar, and 1/4 teaspoon sea salt. Start by combining the brown sugar, butter, and milk in a medium saucepan over low heat. Stir gently until the butter melts and everything blends smoothly.

2-Keep stirring for at least one minute to ensure it’s well mixed. Then, turn the heat to medium and cook without stirring for 3 to 6 minutes until the mixture hits 230°F (110°C) or turns a nice amber color. This step is key for that deep caramel flavor, so watch it closely.

3-Once it’s ready, remove the pan from the heat and pour the mixture into a heat-resistant bowl. Let it cool to room temperature before moving on. This cooling process helps avoid any lumps later, making your frosting smooth and easy to work with.

4-Next, transfer the cooled mixture to a mixing bowl and add the powdered sugar and salt. Mix until it’s all smooth, and if it gets too thick, add milk one teaspoon at a time. This salted caramel frosting comes out creamy and ready to spread on your favorite baked goods.
