Thick and Chewy M & M Blondies

Blondies are an easy and simple dessert with so many add in options. We love a soft and chewy M & M cookie, but now you can eat them in a thick and chewy M & M blondie. They have the delicious flavors of butter and brown sugar, topped off with chocolate M&M's for a delicious blondie.

Blondies are a great dessert when you don’t want to cook multiple batches of cookies. One pan and you have 24 bars to feed a crowd.

I shared this recipe on our local lifestyle show (Studio 5) and have received many email requests to share the recipe. They really are so incredibly easy to make with just a couple of ingredients and they taste absolutely amazing!

On the set of Studio 5, the camera guys and producers kept nibbling on these . . . they are so delicious! They live up to their name being thick and chewy.

  1. I have such a weakness for M&M's...they are just so yummy! This looks like it would work perfect for my addiction. Plus I could use the seasonal M&M's and call it Easter (or whatever holiday) blondies! Thanks for the recipe and for sharing at my Real Family Fun link party.
  2. These look delicious! We have plenty of M&Ms around right now because we are potty training our youngest with them... this sounds like a treat for the rest of us! :) Thanks for sharing this last week on Saturday Show & Tell on Cheerios and Lattes! You are Featured Favorite this week; we can't see what you six have been up to this week!

  3. I hate to be a Debbie Downer...but this recipe did not work at all for me. Very disappointing! And of course I made them late evening for my 5th graders class function the following day and was in a bind when they flopped. An equal sugar and flour ratio seems to be the biggest problem. I baked mine for almost an hour and they are still way too gooey and underdone in the middle. I ffollowed the recipe exactly. Perhaps a few more test runs are in order. It is very disappointing to waste time, energy and ingredients on a recipe that I should have confidence in.
