Heat VitaFiber syrup in microwave until bubbles form (about 30 seconds). Add melted butter and vanilla.
Stir dry cocoa mix into wet VitaFiber syrup mix until crumbly. Using hands, knead mixture until a dough is formed.
Shape dough into a ball, then flatten out. Cut into strips and roll out each strip into a rope about the diameter of a Tootsie roll. Cut dough rope into Tootsie roll size pieces.
Wrap each roll in small rectangular pieces of wax paper if desired. Store rolls in refrigerator so they will be firm.
Can replace vanilla extract with other flavor extract such as orange or mint.May be able to replace Vitafiber with maltitol syrup, but Natvia (additional sweetener used) would need to be reduced.Makes 3 dozen rollsPer roll: 15 calories, 0.9g fat, 10.6mg sodium, 3.3g carb, 1.4g fiber, 1.5g erythritol, 0.4g net carb, 0.6g proteinPer serving (6 rolls): 90 calories, 5.4g fat, 63.6mg sodium, 19.8g carbs, 8.4g fiber, 9g erythritol, 2.4g net carbs, 3.6g protein
