Melt the butter in a saucepan over medium heat. Add the heavy cream and sugar. Whisk until smooth. Simmer over medium low heat for about 35 minutes, whisking occasionally. It’s done when it’s reduced by half and is thickened, but still pourable.
Notes
Be careful not to allow the mixture to brown. Lower the heat if necessary.
If using powdered erythritol, increase the amount of sweetener to 2/3 cup.
