There’s an undeniable magic to a classic s’more – the crisp graham cracker, the rich melted chocolate, and that perfectly toasted, ooey-gooey marshmallow.

Discovering the Secret Ingredient: M&M’S® Chocolate Bars

My journey to creating these sensational s’mores bars began with a simple shopping trip to CVS Pharmacy™. It was there that I stumbled upon the innovative M&M’S® Chocolate Bars, and immediately, my dessert-making instincts kicked in. Traditional s’mores rely on standard chocolate bars, which are perfectly fine, but these M&M’S® Chocolate Bars promised something extraordinary. Imagine a classic chocolate bar, but instead of plain chocolate, it’s generously studded with those beloved M&M’S® mini candies. This discovery instantly sparked the idea of elevating the s’mores experience, moving beyond the ordinary and into a realm of enhanced flavor and texture.

The beauty of using M&M’S® Chocolate Bars in these s’mores is multifaceted. First, the mini M&M’S® within the bar provide an exciting textural contrast – a satisfying crunch that complements the gooey marshmallows and chewy cookie base. Second, they introduce a burst of vibrant color, making the bars not only delicious but also visually appealing. Lastly, the inherent deliciousness of M&M’S® chocolate, combined with the convenience of a bar format, makes them an ideal choice for melting smoothly and evenly over the cookie crust. This simple swap transforms a good s’mores bar into a truly monstrously good one, ensuring every bite is packed with delightful surprises.

The Anatomy of a Perfect S’mores Bar

What exactly defines a s’mores bar, and what makes these Homemade Monster S’mores Bars stand out? It’s all about the layers, each contributing its unique character to the overall symphony of taste and texture. Our s’mores bars feature a robust and incredibly flavorful cookie layer that forms the foundation. This base is crafted from a rich blend of butter, brown sugar, creamy peanut butter, flour, fragrant vanilla, hearty oats, and finely crushed graham cracker crumbs. The result is a cookie base that is both wonderfully chewy and satisfyingly soft, providing the perfect counterpoint to the sweetness of the toppings. It’s designed to be substantial enough to hold all the delightful elements above it, while still being tender and melt-in-your-mouth delicious.

Layered directly on this incredible cookie foundation is the star of our show: a generous topping of M&M’S® Peanut Chocolate Candy Bars. As this chocolate melts, it creates a smooth, rich, and utterly irresistible layer that perfectly bridges the cookie base and the final marshmallow topping. The embedded M&M’S® minis within the bar soften slightly, adding pockets of delightful crunch and extra chocolatey bursts. Finally, these bars are crowned with a fluffy blanket of mini marshmallows. A quick stint under the broiler is all it takes to transform these white pillows into a golden-brown, toasted delight. The marshmallows achieve that signature smoky, caramelized flavor and gooey texture, just as if they’d been roasted over a crackling campfire, but with the convenience of your kitchen oven.
