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.

Made these for family as a trial run. Made them again with just red and green m & m's for a Christmas Open House. Can do that with any color for any holiday! Will definately make them many times.

DELICIOUS! I used mini Reese's Pieces instead of m&m's and pecans instead of walnuts. I also added some shredded coconut - awesome!
