S'mores Bars

Isn’t it fun that people love s’mores so much, there is a National S’mores Day, just to celebrate the awesomeness of s’mores?

Thankfully, s’mores are good any day of the year, especially days where no campfire is required. Because let’s face it – everyone wants s’mores more often than they can have a campfire.

Peanut Butter S’mores

Recently, I discovered that peanut butter is a delicious addition to s’mores. Just spread it on the graham cracker before adding the chocolate and marshmallow.

For these bars, I ditched the traditional graham crackers (which I think can get kind of dry sometimes), and sandwiched the marshmallow and chocolate between two gooey layers of peanut butter cookies.

Peanut Butter Smores Bars

This is a combination any peanut butter and chocolate fan will love.

They are simple to make and only require five ingredients: peanut butter, eggs, sugar, chocolate, and marshmallows.

Combine the peanut butter, eggs, and sugar in a mixing bowl. Beat to combine and then spread half the peanut butter mixture in a baking pan.

Next, spread the marshmallow creme over the peanut butter mixture.

Break the candy bars into squares and layer the chocolate over the marshmallow creme.

Top the chocolate with the remaining peanut butter mixture and bake for about 20 minutes.

For another kid-approved easy dessert bar option, Monster Cooke Bars are a favorite with everyone. All the flavor and crunch of Monster Cookies in a simple bar recipe.

Chocolate Revel Bars are a classic that will never go out of style. They’re irresistible with a rich layer of chocolate fudge sandwiched between two buttery oatmeal cookie layers.

    4 stars
    These were easy to make and turned out just like the picture. I did use dark chocolate chips, in place of the Hershey bars (I don’t like Hershey chocolate!), But that was purely preference. The only thing that kept it from 5 stars was the peanut butter dough…Sadly, even after being cooked, all I could taste and feel in my mouth was the granulated sugar. Has anyone tried this with powder sugar perhaps? And maybe a little less sugar? I think that because the texture calls specifically for “not natural” peanut butter, that also adds to the sugar content, too. My kids, of course, had no problem eating this recipe as-is!
