This dessert is excellent for any holiday, sporting event (think team colors), bridal or baby shower (think pink and/or blue), or any party in general.

Simply use different seasonal colors of M&M’s, such as pastel-colored candies for Easter, red and green candies for Christmas, or red, pink and white candies for Valentine’s Day. Yellow, orange and chocolate M&M’s work well for Halloween and green candies are perfect for St. Patrick’s Day.

Yields:
One recipe yields a jelly roll pan measuring 10.5-inches x 15.5-inches. When serving the bars to guests, I slightly trim the edges and cut my bars into approximately 2.5″ x 3″ OR 3″ x 3″ squares (give or take). These serving sizes will yield approximately 20 to 24 servings. (Oh, and FYI… my family fights over the cutoff edges!!)

No one on a restricted gluten-free diet need go without because Peanut Butter M&M Bars can easily be made gluten-free. Just one more reason why this recipe is so adaptable and perfect for any occasion.

Peanut Butter M&M Bars freeze well in an airtight food storage container up to two weeks. Therefore, feel free to make an entire batch, eat half, then freeze the other half to serve later. Slightly warm the bars prior to serving.

Could you substitute Nutella? I’ve been on a kick lately
Blessed Beyond Crazy says
Hi Kim! We have never tried using Nutella but you can certainly try it and see how it turns out. Thanks for stopping by! Enjoy! Linda & Anna
Marie says
Does the type of oat matter in the recipe? Quick or old fashioned?
Blessed Beyond Crazy says
Hi Marie,
I would suggest using the quick because they will incorporate better into the batter. However, you certainly can use old fashioned oat. The old fashioned oats will probably be a little more noticeable and the bars may be just a little chewier but, I certainly do not have a problem with any of that. They will taste the exact same.
Thanks for stopping by and I hope you enjoy this recipe!
Have a great day!
