Recipe Ingredients
- 4 oz Sugar-Free Dark Chocolate, chopped
- 3 tbsp Butter
- 3 Large Eggs, separated
- 3 tbsp Powdered Erythritol, divided
- 1 tsp Vanilla Extract
- 1/8 tsp Cream of Tartar
- Pinch of Salt
- Butter and Erythritol, for coating ramekins
- Powdered Erythritol, for dusting
How To Make
Step 1
Preheat your oven to 375°F. Generously butter four 6-ounce ramekins, then coat the insides with a thin layer of granulated erythritol, tapping out the excess. This coating helps the souffle climb and rise evenly. Place the ramekins on a baking sheet.
Step 2
Melt the chopped sugar-free dark chocolate and 3 tablespoons of butter together in a heatproof bowl over a pot of simmering water, stirring until smooth. Remove from heat and let it cool for 3 minutes.
Step 3
Whisk the egg yolks and 1 tablespoon of the powdered erythritol into the chocolate mixture until smooth and glossy. Stir in the vanilla extract.
Step 4
In a large, very clean bowl, beat the egg whites with the cream of tartar and salt on medium speed until soft peaks form. Gradually add the remaining 2 tablespoons of powdered erythritol and beat on high until the whites are stiff and glossy but not dry.
Step 5
Fold one-third of the beaten egg whites into the chocolate mixture vigorously to lighten it. Then fold in the remaining whites in two additions very gently, using slow sweeping motions from the bottom up. Stop as soon as no white streaks remain.
Step 6
Divide the batter among the prepared ramekins, filling them to about three-quarters full. Run your thumb around the inside rim of each ramekin to create a shallow channel – this helps the souffle rise with a flat top.
Step 7
Bake for 12 to 14 minutes until the souffles have risen dramatically above the rims and the tops are set but the centers still jiggle slightly. Dust with powdered erythritol and serve immediately – souffles wait for no one.
Tips
Get Your Egg Whites Right
The bowl you beat your egg whites in has to be completely clean and dry. Even a tiny bit of grease or a drop of egg yolk will stop the whites from whipping up properly, and your souffle won’t rise.
Use a glass or metal bowl, not plastic. Plastic holds onto grease no matter how well you wash it. Wipe the bowl and your whisk or beaters with a paper towel and a splash of white vinegar right before you start, just to be safe.
Beat until the whites are stiff and hold their shape when you lift the beaters, but stop before they look dry or grainy. Over-beaten whites break apart when you fold them into the chocolate and you lose all that air you worked to build up.
Cool the Chocolate Before Mixing
After you melt the chocolate and butter together, those 3 minutes of cooling aren’t optional. If the mixture is too hot when you add the egg yolks, it will start cooking them and you’ll get little scrambled bits in your batter.
You want it warm enough to stay smooth and pourable, but cool enough that you can comfortably touch the bottom of the bowl with your hand. That’s the sweet spot for mixing in the yolks without any issues.
Fold Gently to Keep the Air
The folding step is where most souffles fail. When you mix that first third of the egg whites into the chocolate, go ahead and stir firmly – this batch is just there to lighten the heavy chocolate so the rest of the whites blend in easier.
For the remaining two additions, switch to a rubber spatula and use slow, gentle motions. Cut down through the center, sweep along the bottom, and fold up and over. Rotate the bowl a quarter turn each time.
Stop the second you don’t see white streaks anymore. A few tiny white spots are way better than a deflated batter. Every extra fold pushes air out, and that air is what makes your souffle rise tall.

Frequently Asked Questions
Does erythritol crystallize or have a cooling aftertaste in this souffle?
Powdered erythritol works much better than granulated in recipes like this because the finer texture blends more smoothly into the batter and is less likely to crystallize. In this souffle, the chocolate and butter do a good job of masking any cooling effect, so most people don’t notice it at all.
If you’re sensitive to erythritol’s aftertaste, you can try using allulose instead. Allulose doesn’t crystallize and has no cooling effect, though it’s slightly less sweet so you may want to add a tiny bit more.
