Melt your Cinnamon Roll Quest Bar over a low flame with pumpkin and spices. Adjust spices to taste.
Once melted, remove from heat and stir in whey powder.
Pour into the parchment-lined pan.
Refrigerate or freeze until firm.
I calculated the calories here as 9*(grams of fat)+4*(grams of carbs)+4*(grams of protein), as I do with all of my recipes. Quest does some fancy math because of the high-fiber content that results in fewer calories.
