Preparing the Crust for Gooey S’mores Bars (Chocolate Marshmallow Treat)
First things first, let’s get that delicious base ready! This graham cracker crust is the perfect foundation for our gooey s’mores bars. It’s buttery, sweet, and has that essential crunch. Preheat your oven to 350°F (175°C) and line your 8×8 inch pan with parchment paper, letting some hang over the sides. This helps so much when you want to lift the bars out later!
In a medium bowl, mix together the graham cracker crumbs, melted butter, and sugar until it looks like wet sand. Then, just press this mixture firmly into the bottom of your prepared pan. Make sure it’s nice and even!
Layering the Fillings for Gooey S’mores Bars (Chocolate Marshmallow Treat)
Now for the good stuff – the gooey center! This is where the magic happens for our chocolate marshmallow treat. Pour that can of sweetened condensed milk evenly over the graham cracker crust you just made. It creates a wonderful sticky layer that holds everything together.
Next, sprinkle the milk chocolate chips all over the condensed milk. Be generous! Finally, scatter those adorable mini marshmallows over the chocolate chips. Try to distribute them as evenly as you can so every bite gets some marshmallow goodness.
Baking and Cooling Your Gooey S’mores Bars (Chocolate Marshmallow Treat)
Pop your layered pan into the preheated oven. Bake for about 20 to 25 minutes. You’ll know they’re ready when the marshmallows are beautifully golden brown and puffed up. Keep an eye on them; marshmallows can go from perfect to burnt pretty quickly!
Once they’re out of the oven, the hardest part is waiting. Let these gooey s’mores bars cool completely in the pan on a wire rack. This is really important for clean slices. Trying to cut them while warm will be a gooey mess (a delicious mess, but still a mess!). Patience is key here for perfect squares of this chocolate marshmallow treat.

Making really great gooey s’mores bars is super easy, but a few little tricks can make them even better! I’ve learned a few things along the way that help get that perfect chocolate marshmallow treat every time.
