S'mores Bars with a chewy graham cookie base followed by a thick layer of chocolate, then topped with two types of marshmallows. Each bite is reminiscent of a campfire treat.
I had my first s’mores bar from a bakery that recently opened. I didn’t know there was such a thing as a s’mores bar, crazy huh? The top of this treat was light tan in spots and the edges were super crispy. You could see the little bumps of toasted mini marshmallows on the top. It was sticky, gooey, and chewy. They were good, but the mini marshmallows turned taffy-like and almost pulled my teeth out.
The base is basically butter, brown sugar, an egg (I asked the bakery owner), flour, and crushed graham crackers. I don’t see the need for leavening here so I left it out.
The middle of the bar has to have a good layer of chocolate and semi-sweet chocolate chips work best because it is a happy medium of not too sweet and not too bitter. This would also work well with dark chocolate.
The marshmallow topping needed some tweaking. The topping is where it’s at for these s’mores bars. I first made these with just mini marshmallows scattered on top then baked. Marshmallows are covered with starch which keeps them from sticking to each other. The starch also helps it keep its shape. Just like when you toast a marshmallow over a fire, the outer edge gets dark and slightly crispy (sometimes burnt) and the inside gets gooey. Of course, using marshmallow Fluff (or creme for all of you not located in the northeast US) would give me gooey, but it wouldn’t have the crispness from the mini marshmallows like the bakery. So let’s use both.
A simple hack to easily spread the Fluff...
It gets a little tricky spreading the fluff over the chocolate chips. To get around this, spray or grease a 2 cup measure with oil or butter. If using a 7 ounce jar of creme, transfer the whole thing into the measuring cup. If you’re using fluff, measure about 1 ½ cups of fluff into the measuring cup or 1 heaping cup. Place in the microwave and heat it for 15 to 30 seconds. Now you can pour the fluff over the chips and spread it evenly. The whole thing should pour out easily from the cup because it was greased. I don’t recommend microwaving in the plastic marshmallow creme jar. I can’t tell you how happy I was to figure out this simple step because the worst part of making these s'mores bars was spreading that fluff! It was basically a dope slap on the head attached with a “Duh!”
A few things you should know before making these s'mores bars…
- These s'mores bars need to be completely cooled before slicing and I recommend keeping them in the fridge for at least 4 hours or overnight. Otherwise, it will get messy and harder to eat. The drooping marshmallow is great for pictures, but not for eating without getting it all over you. Unless you’re into that stuff. 🙂
- Here's a great tip: spray your knife with nonstick or baking spray to make slicing easier.
- If you cut them right out of the fridge, you’ll need to push down hard on that knife. You may want them to reach room temp before slicing. I slice them cold.
- Once these are sliced and come to room temperature, they will go back to being gooey. I didn’t skimp on ingredients here so these are thick bars with a good layer of chocolate and marshmallows.
