## Questions & Answers

**Q: What does the birthday cake flavor taste like?**
A: The birthday cake is very good! Taste like Vanilla Birthday cake, however I had to stop ordering that flavor! I subscribe to One bars & got 4 boxes monthly. The 1st few bd cakes were good. Then they were SO Hard I couldn't eat them. I think it may be due to local delivery? Could also be fresher ones in stores. Cost more in stores but the best price I've found was $1.92  @ Walmart! GNC $2.99 
  ( I MUST SAY AMAZON did send me a 2and box free - but they were also hard) Amazon has VERY Good if not the best customer service! I'd give them a 95% rating. Love One Protein Bars

**Q: Do they have sucralose or aspartame in them?**
A: Aspartame and Sucralose are not the same product. Aspartame is derived from 2 different amino acids and is 200times sweeter than sugar. Sucralose is made from sugar and is 600 times sweeter than sugar.

**Q: do these bars have any peanut ingredients?**
A: Here is the Nutrition Facts Other Ingredients:Protein Blend (Oh Yeah! Blend consisting of whey protein isolate, milk protein isolate), Isomalto-oligosaccharides (Prebiotic Fiber), maltitol, glycerine, palm kernel oil, sunflower seed butter, sugar, corn starch, natural and artificial flavors, partially hydrogenated vegetable oil, nonfat dry milk, soy lecithin (an emulsifier), tapioca starch, calcium carbonate, distilled monoglycerides, dextrin, confectioner's glaze, sucralose, red 40 lake, yellow 6 lake, blue 1 lake, red 3 and red 40.WarningThis product contains Milk, Peanuts and Soy.Does not containGluten

**Q: Why do they have partially hydrogenated oil?**
A: The ingredients list palm kernel oil.  Not hydrogenated oil in any form.  The FDA has issued a zero tolerance ban of partially hydrogenated oils.  I don't think any manufacturer would add them.
