I found an icecream from Bluebunny brand, brownie sundae flavor. It has no sugar added plus its fat free, 90 calories in 1/2 cup and ingredients are not that bad. Plus, hard to believe, but it has 5 grams of fiber.
So just take 1/2 cup and put in those 15 calories cones. There you have it, 105 calorie dessert.
