Carefully add the heavy cream to the caramelized sugar while stirring constantly. The mixture will bubble up, so be cautious.

Once the cream is fully incorporated, add the unsalted butter and continue stirring until it melts and the mixture becomes smooth and glossy.
Remove the saucepan from heat and stir in the sea salt. Adjust the amount to your taste preference.

Let the caramel cool down before transferring it to a glass jar or airtight container.

You can use the salted butter caramel as a topping for ice cream, drizzle it over desserts, or use it as a dip for fruits.

Enjoy your homemade salted butter caramel!
