Cook the butter & sweetener on medium high heat until it bubbles for about 2 minutes. Make sure to constantly whisk it.
Turn heat to low & quickly whisk in xantham gum until it dissolves
Turn heat back up to medium heat. Add in half & half & let caramel mixture boil for another 2 minutes, contantly whisking so it doesn't burn
Turn off heat & let caramel cool a bit before serving
Use as a dip for your favorite fruits or to drizzle over a favorite dessert. A wasa cracker with some melted lily's & a drizzle of this caramel hits the spot ;)
