"These were great and easy to make. The kids love them and they are a simple treat to bring in for the class. You can have the M&M color match the season."

"They look beautiful and taste excellent.. This recipe is so versatile. I made the recipe as directed. Also made it GF as someone mentioned in a prior review. Then it was time to play. Put 1/2 c of shredded coconut in the bar, which made it even more delicious. Then the next time. instead of using M$M 's used mini Hershey kisses delici-oh-so! This is definitely a keeper."

"These definitely satisfied my sweet tooth! My husband doesn't like caramel so I did change these up a bit. I put one cup of M&M's in the oat bar mix and before I baked it I pressed another cup of M&M's to the top of them and that was it. I didn't put any nuts or chocolate chips on it or drizzled it with cany coating. Although I would have loved too. But they still turned out GREAT and had chocolate in every bite!"

"Delicious and makes enough for a 4H or Scout meeting. I used fall colored M&Ms and have served them during fall activities. Kids love them!"

"I have made this both gluten free and the regular way, both turn out fabulous. To do gluten free just use Gluten Free Quick Oats(Bob's Red Mill) and any all purpuse gluten free flour. I kept the measurements the same. Great for my GF daughter and the rest of the family couldn't tell the difference."
