I got to tag along with my neighbors last weekend for an amazing camping trip. There is a place in Utah where you go on a hike to the ‘hot pots’ and you get to sit and relax in the nice mother nature hot tub. 🙂  The best part of a camping trip is sitting by the campfire and roasting hot dogs and making s’mores. I like the chocolate on my s’more nice and melty. So when you take the first bite the chocolate oozes out and the marshmallow is perfectly cooked and it makes a huge mess that is impossible to clean up. Doesn’t that sound amazing?

Well a few years back I discovered that you can put a Reese’s peanut butter cup on your s’more and it is life changing! These s’mores bars are so awesome they can be made right in your kitchen and you will get the same amazing gooey taste of a delicious s’more!

  1. I made these and they were delicious! Question: My bottom dough was so thick (and it doesn’t look thick in the picture) did you use the 8×8 pan or a larger one?

  2. Oh my goodness. These look like the best things ever!

    I have got to try this recipe.

    Wishing you a wonderful weekend!
