The first time I made these Reese’s peanut butter blondies was years ago for a family get together. As soon as they cooled and I cut them, the pan was empty in 5 minutes flat.  

I wish I had videoed everyone hovering around just waiting for that first cut.  It was madness trying to get a square!!!  There was no way I was able to photograph them then.  

Everyone raved about these bars and wanted the recipe, so I couldn’t wait to share it here too. I knew this recipe would be a winner because of how much you guys love these Reese’s Peanut Butter Pudding Cookies.

Baking with Reese’s peanut butter cups and Reese’s Pieces may be my favorite thing to do. You just can’t go wrong with adding either one.  I mean just look at these Reese’s Rocky Road Brownies and these Ultimate Reese’s Cheesecake Brownies!

Each bite of these peanut butter blonde brownies has a pocket of marshmallow cream. Add in some Reese’s Pieces and chocolate chips and it becomes one of the best blonde brownies ever!!!

You are going to love how soft and chewy these peanut butter bars are.  If you want them to keep that soft texture, make sure you DO NOT over bake the bars.  They will still taste good, but the edges will be dried out and crumbly.

These peanut butter blondies are seriously so easy to mix up.  Once you mix together the batter and spread it in a pan, they take less than 30 minutes to bake. 

How to make Marshmallow Reese’s Blonde Brownies:

  1. Beat together the butter, peanut butter, and sugar until creamy. Add the eggs and vanilla and beat again. (full recipe at bottom)
  2. Add the dry ingredients and mix until combined. Stir in chocolate chips and Reese’s Pieces.
  3. Spread half the batter in a greased pan. Drop spoonfuls of marshmallow fluff on top and spread out gently.
  4. Drop spoonfuls of the rest of the batter on top and then spread out with a spatula.
  5. Sprinkle more chocolate chips and candies on top. Bake and cool.

My biggest suggestion when you make blonde brownies is not too over bake them. Let me say that again…do not over bake these bars!!!

The dough will look wobbly and undone when you take it out of the oven.  Just trust me, and do not keep them in the oven longer than 30 minutes.  Once they cool, they will set up and you will be able to cut them into big or small bars.

We like them a little bit under baked, so I usually bake ours about 25 or 26 minutes.

PRO TIP: If you are making these blonde brownies (or any other ones) for a bake sale, you will want to bake them for the full 30 minutes, so they are not as gooey and can be cut into pretty bars.

    I am not one of those people who make diet resolutions come January. Yes, I should change my diet and yes I should exercise more, but I also know I cannot resist a dessert like this one! Why put pressure on myself??? I can see why everyone was waiting for the your to cut the squares!

      I just need to go on a moderate diet…eat healthy and enjoy one treat each night. That should work right?

      I’m really not sure why I make resolutions regarding diets because I usually fail by the afternoon of the first!!!

    These look awesome!! And anything with peanut butter derails any hopes of dieting I have. Note that I said hope of dieting and not actually dieting. I’m a realist. : )

    These look amazing and I think I will make them for the big game next week. I don’t have a good track record with making blondies so I liked when I saw “soft and chewy” to describe these. Think I’ll make them Saturday night and cut them on Sunday, hopefully they will stay moist.

    I am making these tonight, and I am not very savvy in the kitchen… so I wasn’t sure what size pan to use, so hopefully these turn out alright..
    Thanks <3

    These were amazing! I had all the stuff on hand to make them and I’m still snacking several days after. Of course, I made the full recipe and I live alone! I loved them so much I had to tell people about it on my blog. Thanks for the recipe!

    To Haley, I once had to smuggle a bag of reeses pieces® in to a movie theater…when the movie “ET” first came out..the movie house was small, and cheap, and the consession stand wasn’t selling them at the time.. now the movie theaters sell reeses pieces® even for the “ET” anniversary re-releases. In theaters…I also like “blondies” which are like brownies (without the chocolate) but these are amazing. 🙂

    So I don’t make much…and only remember brown sugar being used for choc chip cookies my mom makes.. I’m in the middle or well beginning of making these and was packing the brown sugar… this may be silly questions since if it needed to be packed you probably would’ve put that but…. just to be sure…. do I pack it or just scoop it up like you would granulated sugar?
