Having kids in school means lots of parties, banquets and the giving of teacher appreciation gifts.

    1. Hm, I’m not sure Barbara. I would reduce your cooking time by about 5-10 minutes, it’s possible your oven runs hotter than mine. It’s also possibly a difference in cake mixes, perhaps mine was a “pudding in the mix” extra moist kind of mix? Sorry to hear that – let me know if you make them again and either of these tweaks helps!

  1. I just made these with a Duncan Hines mix, not one with pudding, and added white chocolate chips. These are fabulous and the potential combinations are endless. Thanks for this easy and wonderful recipe.

  2. I made these M&M. Bars last week and they were the best bar treats we ever had. They seemed easy and they were. My husband loved them, my Kali and Kayden gave me thumbs up Grandma. And my Daughter thought they were the perfect texture, she wandered if you could make cookies with the recipe? I did miniature M&M’s and some chocolate chips. Excellent recipe, will be making them a lot.

    1. I’m so glad you loved them!
      I’m sure you could make cookies with them.

      Thanks for taking the time to comment.

  3. 5 stars
    I made these bar cookies but added 2/3 cup oatmeal.1/3 cup coconut, 1 tsp extra vanilla and 1 tsp cinnamon 1/4 c water //They were outstanding!! The Cake mixes do make a slight difference but once they are completely cooled they are wonderful. Can’t wait to try other flavors! Thank you so much for sharing your recipe. They were gobbled up so fast I never had time to take a photo.
