Low Carb Hot Buttered Rum

So here’s the deal, hot buttered rum is usually loaded with sugar.Traditionally recipes call for anywhere between 1/4 cup to an entire cup (!) of sugar. Not today, mixology snobs! As per usual, I’m throwing tradition to the wind and doing things a little differently. Instead of sugar, we’re using a low carb sweetener as a replacement.

I recently fell in love with monkfruit sweetener by total accident. I sent my partner to the health food store to pick up Swerve for a recipe I was working on, and they were out. We spent some time on the phone hashing out the ingredient labels while googling until he found something on the shelves that I could have: Lakanto Monkfruit Sweetener.

Sweeteners are hit or miss for me, so I was hesitant to even try. I almost sent him somewhere else to look for Swerve, which is Erythritol and Stevia. I loathe xylitol, love Erythritol, feel pretty “meh” about Stevia, and had never tried monkfruit. Since the Lakanto brand had monkfruit and my beloved Erythritol, I decided to give it a shot. OH. MY. LAWD! I’m a total convert for sure; I much prefer the flavor of this blend. It got me excited about making sweet stuff, which I hardly ever do! So that’s what I’m using in the recipe, but feel free to use whichever sugar-free sweetener you prefer.
