While these Low Carb Chocolate Truffles are not low calorie, they are compliant with keto or low carb diets. Best of all they are delicious and very easy to make. I’ve included two recipes for the truffles: with or without sugar substitutes, one made in the microwave and one in a double boiler. Perfect for a Valentine’s Day or special occasion treat!

How to Incorporate Truffles into a Low Carb Diet

While the cream used in truffles is not a problem with low carb or keto diets, the sugar is often problematic. The recipe below uses sugar substitutes, allowing you to satisfy occasional sugar cravings without spiking blood sugar or setting up an insulin response.  

Cocoa, the primary ingredient in 90% dark chocolate, even has a few health benefits.  Low sugar aside however, these truffles are not something you would want to eat on a regular basis if your goal is weight loss. I keep them in the freezer (out of site) and pull one out on days when the sweet tooth is relentless, or when a special occasion calls for dessert or chocolate

What Kind of Chocolate is Best to Use for Low Carb Diets?

I made the first round of chocolate truffles with 8 oz. of Ghirardelli Bittersweet Chocolate (60% cacao) and they were the best truffles ever.  I didn’t realize how much sugar could be in Bittersweet Chocolate however (when it says 60% cacao it means the remaining 40% is sugar).

I adapted the recipe to include unsweetened chocolate and added in some sugar substitutes.  Still great, a little more bitter, but a lot less sugar!

Are Sugar Alcohols Natural or Artifical?

Sugar substitutes that do not spike blood sugar can be natural or artificial.  Sometimes referred to as “sugar alcohols”, they can be from natural souces or chemically manufactured.  Sugar alcohols include such names as maltitol, xylitol and erythritol.

With respect to spiking blood sugar and insulin response, some of these sugar alcohols are fine, but others…not so much.

The worst sugar substitute is Maltitol,  which has 75% of the blood sugar impact of sugar, but also only 75% of the sweetness. This means maltitol and table sugar end up being about equal when you’ve added enough maltitol to get to the desired sweetness.

Pros and Cons of Other Sugar Substitutes

The currnet medical research indicates that  Saccharin,  Aspartame, and Acesulfame potassium have evidence of negative health issues, but there are conflicting studies (of course).

Sucralose (or splenda) is a decent artificial sweetener, as far as impacting blood sugar, glycemic index and  insulin. 

Natural sugar substitutes that are considered “good” with respect to glycemic index are Stevia and/or Erythritol

Caveat for Using Sugar Substitutes for Weight Loss

With respect to anecdotal impacts of using sugar substitutes, some people believe that using sugar substitutes tricks the brain into thinking it is getting sugar and therefore derails the effort to eliminate sugar cravings. If your weight loss has stalled, this idea might be something to test out on yourself.

Best Sugar Substitutes to use in Baking:

Truvia, Swerve and Natvia are blends of Erythritol and Stevia and I find them the best taste to cook with.

The recipe below used a combination of a granular sweetener (Truvia) and a liquid sweetener (Stevia).  The reason for this is that many of the powdered or granular sweeteners can result in a gritty texture (not so much in truffles because it is heated up with the chocolate).

Liquid Stevia on the other hand can leave the chocolate on the bitter side.  A combination of both of them in this truffle recipe made a truffle that was nearly indistinguishable from the truffle made with the sugary bittersweet chocolate.  Both recipes are included below for your cravings pleasure.

Pull out one of these delectable, hidden truffles when you need a chocolate fix.  Just know that the cocoa has quite a bit of caffeine so don’t eat too close to bedtime.

Enjoy either way, the classic truffle or using sugar substitutes!!!   Just make sure if you do the Ghirardelli version that it’s on cheat day!

  • Double boiler or microwave


  • 8 oz Semi-sweet chocolate bar or bittersweet
  • 3/4 cup heavy whipping cream fluid
  • 1/4 tsp salt
  • 1 tsp good vanilla I used vanilla bean paste, but choose your own
  • 1 Tbsp bourbon (optional)
  • 1/2 cup crushed pistachios or hazelnuts or pecans


Double Boiler Method (note: the microwave method below can be used with classic or sugar free versions of truffles)

  • Place chocolate and cream in a double boiler or a stainless steel bowl placed over a pot of lightly simmering water. Stir constantly until everything is melted and mixture is smooth. (maybe 5-10 minutes). Do not heat over high heat or mixture might separate. Stir with a spatula and watch it melt until it is smooth and creamy.
  • Stir in salt, vanilla and bourbon while mixture is still warm.
  • Pour into a pie plate or baking dish, cover with plastic wrap and refrigerate for at least 1 hour to overnight.
  • When ready to make truffles, remove from refrigerator and let it get soft enough to form balls. While waiting, use a food processor to crush pistachios until you have 1/2 cup crushed nuts.
    Using a melon baller or spoon, make balls (about 1 inch in diameter). Roll between palms and then roll in the crushed nuts.
  • Refrigerate, but don’t serve ice cold; remove from refrigerator about 10 minutes before serving.
  • Can be refrigerated for up to 10 days or freeze and consume at a later day (but consume within 10 days of thawing).
