Six Layer Peanut Butter S’mores Bars | Gooey, Chocolatey, & Irresistible

🎉 Introduction

If you’ve ever sat by a campfire with sticky fingers from making s’mores, you know just how magical the combination of graham crackers, chocolate, and marshmallows can be. But what if you could take those nostalgic flavors, add a creamy peanut butter twist, and transform them into a rich, layered dessert you can bake at home? That’s exactly what you get with these Six Layer Peanut Butter S’mores Bars.

This dessert is everything indulgent rolled into one. It starts with a buttery graham cracker crust, followed by creamy peanut butter, marshmallows, chocolate chips, peanut butter chips, and a luscious ganache layer made with heavy cream and more chocolate. Each bite is chewy, gooey, crunchy, and oh-so-satisfying.

Unlike traditional s’mores that you need a fire to make, these bars are baked in the oven, which means you can enjoy them any time of year. They’re perfect for potlucks, bake sales, family gatherings, or just as a decadent weekend treat. With six distinct yet harmonious layers, they’re as impressive to look at as they are delicious to eat.
