Keto Chocolate Soufflé is light and airy but oh-so-decadent. Don't be intimidated, it's easier than you think. This sugar-free soufflé recipe will make you feel like a keto baking rockstar!
Preheat the oven to 375ºF and grease four 4-ounce ramekins with butter. Dust each lightly with a little bit of granulated sweetener.
In a medium saucepan, combine the cream, 2 tablespoons of the water, and the butter. Bring to a simmer, whisking until the butter melts. Remove from heat and whisk in 3 tablespoons of the sweetener.
Add the chopped chocolate and let sit for a few minutes to melt, then add the espresso powder and vanilla extract and whisk until smooth. Let cool a few minutes.
Whisk in the the egg yolks. The mixture will thicken up considerably, this is normal. Slowly add the remaining water, whisking until it thins and smooths out again.
In a large bowl, beat the egg whites, cream of tartar, and salt until frothy. Slowly add the remaining 2 tablespoons of sweetener and beat until the whites become thick and glossy and stand up in stiff peaks.
Add about 1/3 of the egg whites to the chocolate and fold in to lighten, Then carefully fold chocolate mixture back into remaining egg whites until just combined.
Divide among the prepared ramekins and bake 14 to 16 minutes, until puffed up and the top looks mostly dry. Remove from the oven and sprinkle with powdered sweetener. Serve immediately.
Notes
Tip! Resist opening the oven to check on the soufflés until they are nicely puffed up and don't seem to be rising much anymore. Cooler air hitting them early on can cause them to fall. When you do check on them, open and close the door carefully. Storage Information: Chocolate soufflé is best served on the day it is made, but you can store cover the leftovers and store in the fridge for up to 3 days. Rewarm it gently (it won't rise again) and top with whipped cream or keto chocolate sauce.
