    Easy Peanut Butter Blondie Bars--brushed with dark chocolate

    Let’s get this over with, shall we?

    The workday, that is.  That last 8 hour stretch before the magical couple of days formally known as the weekend can begin.  Only 8 hours (hopefully less than that, by the time you’re reading this) separates you from freedom (granted you have the same schedule as me), and hopefully by the end of this post I’ve convinced you of the absolute necessity for you to immediately go home and make these peanut butter blondie bars.

    Why?  Because they are incredible, they are easy, they are simple to make and heavenly to consume.  Thick and chewy, chock-full-of dreamy creamy peanut butter and oh-so-artfully (or maybe not-so-much, let’s be honest) brushed with premium dark chocolate for that final, perfect flair. All the soft, chewiness of peanut butter cookies, no scooping required.

    Maybe, if you’ll look closely you’ll notice the fine sprinkling of crushed sea salt scattered over the surfaces of these squares.  I ultimately omitted the sea salt from the final recipe; while I’m usually a fan, I felt that it didn’t add much to the peanut butter bars (which already have naturally salty undertones to them thanks to the peanut butter).

    Feel free to experiment with a sprinkle or two if you’d like, though.

    Now, why you should make these immediately:

    I hate to use the word moist (if only because I know so many people dislike it) but I don’t really know a way around it to properly convey the texture of these bars to you (“damp”, “sweaty”, “slightly wet”, all of these are significantly less appealing and none have quite the same connotation).  They are soft, definitively moist, heavy with peanut butter so that they hover right on the line of appearing underbaked (which generally tends to be the line that I strive for when making baked goods).

    They are a delicious way to enjoy peanut butter without making cookies, a twist on basic brownies, and they are, very, very easy.

    Happy Friday, I hope your weekend is care free and peanut-butter-y (um, unless you’re allergic, of course…!).

      I’d merged two of your great recipes to make Peanut Butter Blondies Bites with Ganache. I left out the milk and baked them like your brownie bites. 1/2 recipe makes 27, or 24 with a generous amount left for licking the bowl. 350°F for 18 minutes, like the brownie bites. I have pictures, but don’t think there’s a way to add them here.

      Hi! Hope you are having a great day 🙂 I was wondering if I half this recipe, what size pan should I bake it in?

        Hi Nan! I believe an 8 inch square pan will work here. 🙂

          Thanks so much for your quick responses! I have another question- sorry I have so many questions lol- can I sub the brown sugar for white sugar mixed with pure maple syrup or maybe just plain white sugar? I love brown sugar in recipes but I use it so much that I keep running out of it 🙂

          As long as you have the ratio correct for the mix I don’t see any reason it wouldn’t work. 🙂

      I’m pre-rating it 5 stars. I have a half batch in the oven now, since it’s just me. This is easily done by hand with a wooden spoon, if you would like. I’m sure these are as good as the Snicker Doodle Blondies. I did mistake my 1/2 tablespoon for a 1/2 tsp for the baking soda, so mine will be too puffy, but that will be fine. I’m sure I’ll make another half batch soon!

          I’m not really sure but it shouldn’t be an issue. Actually many people strive to achieve a slight crackle on top. 🙂

      Hoping these come out okay. I’m so used to your recipes having weights this really threw me off lol.

        I hope you love them, Ruth! This is an older recipe from before I used weights, I’ll have to get it updated with weights soon!

      The bars look delicious, I would love to try them. What is sweet cream butter? I suppose I can use normal butter instead?

        Thanks Adina! And yes, just regular butter would be right 🙂
