Delicious And Easy Chewy S’mores Bars

I LOVE s’mores, but I don’t always have access to a campfire, and I don’t always love the mess they make. These chewy s’mores bars are the perfect dessert to make for a crowd when you’re craving these flavors.

These are a takeoff of a shortbread bar recipe, and it works perfectly.

Even Mister Man liked them. This was his reaction to them after he’d finished his sample.

What size marshmallows should I use?

These work well with either mini marshmallows or the full size marshmallows. However, I prefer the full size marshmallows because they make it easier to cut the chewy s’mores bars cleanly.

Mini marshmallows cover more surface area, but when I place each large marshmallow half on the graham cracker shortbread crust, and that is the perfect size for each individual bar, so I simply slice around it.

That said, use what you have on hand.

Should I use chocolate chips or chocolate bars?

Either works, but creating a single layer of chocolate chips is easier than making sure that the chocolate bars cover all the graham cracker crust.

You can absolutely use chocolate bars, however. It takes about seven full size bars to cover the base layer.

What if I don’t have a food processor?

For the smoothest graham cracker crumbs, a food processor works great. However, if you don’t own one, you can definitely still use other methods.

My favorite alternative is to place the graham crackers into a zip top freezer bag, remove as much air as possible, and then use my rolling pin to crush them.

Why a freezer bag? They are thicker, and the graham crackers are less likely to poke holes in them.

My other favorite is to simply purchase graham cracker crumbs. Yes, this is a thing now where you can purchase them already crushed!

What kind of baking pan should I use?

You definitely need a 9×13 pan for this. I prefer to use a glass baking dish since you will cut the bar cookies in the pan, and I do not want to scratch a metal pan.

The glass dish also lets it cook evenly as the glass retains the heat without getting hot immediately.

If you only have a metal 9×13 pan, that will also work. It does not need to be a nonstick pan, as you will grease it with butter before you add any ingredients.

How to Make S’mores Bars

Crush your graham crackers. I love pulsing them in my blender, because it’s easy and not messy.

I’ve found that the best way is to break the graham crackers in their quarters and do half, pulsing until they’re just about crushed, then adding the other half and proceeding the same way.

Beat together the butter and sugar until light and fluffy. It doesn’t get light and fluffy if the butter is cold, so make sure it’s at room temperature.

Add the egg and vanilla and beat again. until well combined. Add the baking powder and mix once again.

Add the graham crackers and flour and stir until just combined. Grease a 9×13 pan and put the graham cracker mixture into the pan, reserving around a cup or a little more for a topping.

This is a press with your fingers exercise. I tried to be dainty and use my spatula, but it didn’t work.

Pour the chocolate chips over the crust into a nice, even layer.

Take the marshmallow in your fingertips and use your other fingertips to twist and pull it apart so you have two non-smushed marshmallow halves. You can also use scissors to cut them, but the scissors tend to get sticky and hard to manage by the end.

Place the halves sticky side down in rows over the chocolate. I did five halves per row and eight rows, but do what works for you.

Crumble the last of the graham cracker mixture over top that, and voila!

Bake your chewy s’mores bars in a 350 degree oven for 25-30 minutes. Let them cool fully before cutting.

Use a bench scraper to cut 8 rows of five, with one marshmallow half on each cut bar. This works better than a knife and avoids scratching your baking pan.

Once they’re ready, serve them at room temperature and store them in a sealed container for three or so days. If they last that long….
