Preheat oven to 350º Fahrenheit. Grease 6 6-ounce ramekins or other small oven proof dishes with coconut oil, butter, or other oil of choice. Set ramekins on a baking sheet.
Place 1/4 cup allulose and egg yolks in a medium mixing bowl. Beat with a hand mixer (you can use a stand mixer for this step as well) until the sweetener is dissolved and the mixture is thick and yellow.
Fold 1/3 of the egg white mixture into chocolate mixture to lighten. Next, fold in the remaining egg white mixture. Divide mixture among the prepared ramekins.
Bake for 11-15 minutes in the preheated oven. When done, the edges should be set, but the centers should still jiggle slightly.
Allow to cool slightly before serving, so fingers and tongues do not get burned. These are best served hot from the oven. If desired, sprinkle with powdered sugar or chocolate curls. Cover any leftovers and store in the refrigerator. To reheat, uncover and place in a 200º Fahrenheit oven until slightly warm–about 15-20 minutes. Do not microwave.
