White Chocolate, Peanut Butter M & M Blondies Recipe

Some exciting things happened yesterday:  my blog turned two years old, it was the one year anniversary of the hubby and I moving into our very first house, and my countdown to Christmas finally hit double digits (please don’t hate me for saying this…but only 98 days left!).  It was a great day overall.  Thank you all ever so much for your kind words for my “blogiversary”….I really appreciate each and every comment!  You guys are the greatest.  That’s why I’m bringing you these White Chocolate M&M Blondies today.  You can thank me later.

Yes, I have more blondies to share with you today.  If you missed the ones I posted last week, here they are: Cake Batter Blondies.  I don’t even know if I could choose between the two, but honestly, I think these might just be my new favorite blondies.  You can be the judge.

These babies also have white chocolate chips in them but, in addition, have peanut butter and mini M&M’s.  They are pure awesomeness.  Why do mini things make things look cute? I don’t know… but it’s true.  I love baking with M&Ms, in general. They add such a pop of color and of course, they taste great.

If you’re allergic to peanuts, you can always substitute Biscoff spread or any other nut butter that you can tolerate for the peanut butter.  Have fun and be creative. Enjoy your Wednesday!

These are a few of my favorite things: cooking, baking, Broadway musicals, cruises, Disney World, Christmas, thunderstorms, 80's and country music, and my favorite pastime has ALWAYS been baseball. Go Yankees!

    I’ve made a blondie once and while I loved it, it didn’t come out nearly as thick as yours which I love! Can’t go wrong with PB and M&Ms, yum.
    Wow, so many wonderful things…congrats again on your 2 year blog anniversary!
    Congrats on your 1 year anniversary for being in your house! My hubby and I have been in our first house for 14 months, so pretty close to you.
    Countdown to Christmas already?! Cute. 🙂 I haven’t been counting but I’m guilty of already thinking about what cookies I want to bake for the season. Hehe.

      Thanks, Tina! They did turn out nice and thick, I was happy!

    Looks yum. I kids would try and pick all of the m&m’s right off the top!

    • September 18, 2013 at 11:50 AM #

      I might have done that, too! 😉

    Congrats on your 1 year house anniversary… cool! I love how the m&m’s make these blondies so colorful. Plus I’ve been craving m&m’s so badly… particularly the peanut butter kind.

      Thanks for the congrats, Ruby! I do love the colors the M&M’s give 🙂

    Yay to your 1 year house anniversary. I’m celebrating my 1 year house anniversary next month! 🙂 It’s also our first home. Don’t you just love being a homeowner? It’s different than being a renter.

    These blondies are a great way to celebrate! And I always welcome more blondie recipes as I just LOVE them! 🙂 These look delicious! I love the colorful M&Ms on top. So festive! 🙂

    Happy Birthday Wishes & Dishes!!! My husband will love these so I will be making them tomorrow as I have all the ingredients on hand. The only substitute will be regular size M&M’s instead of mini’s.

      Regular size will work just fine! Thanks, Erica 🙂

    Seriously, is there anything that isn’t made great with any of these three main ingredients?! White chocolate, peanut butter, and M&Ms are all big hitters in my book!! Thanks for the wonderful recipe and congrats on another great post!!
