So good!
by Tiffy on 2/5/2013
I'm not sure if I bought these because of the chocolate or marshmallow, but either way, I'm glad I bought these. They definitely fill me up and satisfy my sweet tooth. I would buy these again for sure.
wow! so good!
by Kimberly L on 7/12/2013
I LOVE these bars! I am a complete chocolate junkie and that's the one temptation that can throw me off a diet. I love these marshmallow chocolate cookie bars. They are much better than a Snickers or other candy bar. It tastes so good - rich, creamy & crunchy. It takes that craving away and totally satisfies me. I love these bars and highly recommend them to anyone trying to diet or get away from the chocolate monkey.
Very good!
by Joanne on 9/3/2013
I really like these bars. They are filling and have a great taste!
Absolute favorite
by Sherry M on 12/21/2013
If you like marshmallow this is a good tasting bar. I like marshmallow and this bar taste like marshmallow. I have had some that do not taste like marshmallow - this one does.
by Gail on 1/12/2014
This was a Real candy bar.
Acandy bar and cookie all in one!
by Robin on 3/1/2014
Unbelievable bar. I do not feel deprived at all when eating this bar. It satisfies my craving for cookies, candy and chocolate. A winning bar!
Best chocolate bar
by J on 3/22/2014
This is my favorite sweet chocolate bar. Of all the chocolate flavored products by Wonderslim, this one has the greatest taste. If you like Oreo's, this bar is for you!
by Bernie on 5/31/2014
It's hard to believe these marshmallow bars are diet bars! They are so good, I feel guilty when I eat one!
by Dana on 6/15/2014
These are amazing...could eat these all day long. Good sweet treat!
by Rosina on 9/12/2014
I like these a lot, helps the cravings nicely.
Best cookie ever
by Lillie on 10/30/2014
I have been purchasing protein products from another source for more than twice the price of Wonderslim and they do not taste as good as the products I have purchased from Wonderslim. I would have saved a lot of money if I had discovered your product sooner and enjoyed the food more.

number 5
by Patricia on 6/14/2015
I have to admit, this bar is extremely delicious! I fell in love with this bar. It is a light texture and tastes amazing. I highly recommend this bar. It is not overly chocolatey, but is almost like having a smore.
LUV LUV LUV these bars!!

Declicious but does it work with medifast?
by Gina on 6/24/2016
These are delicious. You don't feel like you are dieting with this product. Cost is great. But does this work in conjunction with medifast?

Sooo Good!
by Julia on 7/19/2016
This bar is PERFECT for my afternoon sweet tooth. I crave sweets like nobody's business after my lunch and this bar is thoroughly satisfying.

Only thing, the marshmallow sticks to the packaging, so if you're desperate like me, you'll often times find yourself licking the wrapper.
Highly recommend

Chocolate marshmallow bars
by Cheryl on 3/18/2017
These bars are wonderful! I love them! They do keep you full.
by Michele on 3/23/2017
Really good but are higher in calories than those by Medifast. I just cut them in half, much better tasting than Medifast
Choose Me, Choose Me, Choose Me!
by Chocolate Chick on 5/9/2017
I love this bar! It hits all of my chocolate notes. I eat it in the morning with coffee, I eat it in the evening with a cup of tea, I eat it as an afternoon treat with a glass of milk. I've shared it with my boyfriend(who is not dieting, but loves chocolate) and he says that I should buy more. I have bought more, but haven't told him yet, I would have to share them :) So delicious!!!
BTW I have been eating wonderslim treats and meals for about 10 weeks and I have lost a solid 14 pounds! Although I have done my fair share of non-diet days, I am looking and feeling great without having to feel deprived.

* Results not typical. Weight loss will vary for each person based on their individual weight, metabolism, age, activity level and commitment to their plan.
Indescribably good!
by Cookie on 8/23/2017
When I ate the first bite, I thought I had accidentally gotten hold of a delicious treat from a bakery. How can you possibly make something so healthy and yet so yummy! Keep these in stock.
by Erika on 1/4/2018
I have no idea how you managed to make these taste so good given the fact that it's a diet bar- but they are so good you can't even tell they are a diet food. Others in my life have tried them (even non-dieters) and like them. They are on my list of staple items for this diet.
by Gilda on 3/1/2018
I put this bar into the fridge and the topping becomes chewy and with the chocolate it is just divine. My husband keeps wanting to melt them into smores
by rb on 4/1/2019
These do not taste like diet food at all- so delicious and filling!!
Go down a little too fast
by Caprice on 7/4/2013
Could probably eat 3...but good taste and decent protein. 3 bites and IRS gone!
Love it!!
by ANGIE on 2/3/2014
This was really good. You know you have winner when you have to lick the leftover marshmallow off of the wrapper. Really good bar, cookie part was crunchy, marshmallow was soft and chewy.
Better than expected!
by Stephanie on 8/7/2017
This bar blew past my expectations of a protein bar! It is so good and chocolaty!
Simply delicious
by Marian on 5/3/2019
I feel like I’m cheating
by Marian on 5/3/2019
Not Great
by Alan on 9/5/2017
A little too sweet and kind of messy. Prefer a bar with harder crunchier consistency. I will try freezing it. That soft frosting on the top makes me gag!
Not Great
by Alan on 9/4/2017
I was hoping this might be a great tasting bar but it is not. Weird taste and kind of messy. I might try freezing it to see if it makes it a little firmer.
