Preheat the oven to 400F. Chop the chocolate bar into small pieces. In a microwave-safe, add the chocolate pieces together with the salted butter. Microwave for 45 seconds until the chocolate is completely melted. Once done, set aside to cool completely.
Meanwhile, grease four small ramekins with some butter. To the chocolate and butter mixture, add the swerve sweetener and egg yolks. Combine using a whisk until well incorporated.
To a stand mixer bowl, add the egg whites. Whip the egg whites on medium speed using the whisk attachment until stiff peaks form. Then, gently fold 1/3 of the egg whites into the chocolate mixture using a spatula. Add the rest of the egg whites and gently fold until fully incorporated.
Divide the batter among the four greased ramekins using an ice cream scoop. This ensures that each ramekin has an equal amount of the batter hence equal net carbs per ramekin serving. Gently smooth the top of the batter using the back of a spoon to get an even top once baked.
Transfer the ramekins to the oven. Turn down the oven to 350F. Let the soufflés bake for 7-8 minutes until the edges are firm and the center is still soft and molten. Allow the soufflés to cook for about 1 minute once baked before serving. Serve with a dollop of whipped cream if desired.
