1. Start by heating the granulated Erythritol or keto-friendly sweetener in a heavy-bottomed saucepan over medium heat. Stir occasionally with a wooden spoon until the sweetener melts and turns amber in color.
2. Carefully add the heavy cream to the caramelized sweetener while stirring constantly. The mixture will bubble up, so be cautious.
3. Once the cream is fully incorporated, add the unsalted butter and continue stirring until it melts and the mixture becomes smooth and glossy.
4. Remove the saucepan from heat and stir in the sea salt. Adjust the amount to your taste preference. Add vanilla extract if desired.
5. Let the keto salted butter caramel cool down before transferring it to a glass jar or airtight container.
6. You can use the keto salted butter caramel as a topping for keto-friendly ice cream, drizzle it over keto desserts, or use it as a dip for low-carb fruits.
