Preparation Instructions
Follow these simple steps to create your irresistible Monster Chaos S’mores Bars:
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C).
Line your baking pan with parchment paper, leaving a bit of overhang on the sides to lift the bars easily once baked.
Step 2: Make the Crust
In a mixing bowl, combine the graham cracker crumbs, brown sugar, and melted butter. Stir until the crumbs are fully coated and the texture resembles wet sand.
Press the mixture firmly into the bottom of your prepared pan to form a compact crust.
Bake for 8–10 minutes until lightly golden, then let it cool slightly.
Step 3: Layer the Chaos
Spread a thin layer of peanut butter (if using) over the crust.
Sprinkle evenly with chocolate chips, chocolate chunks, marshmallows, candies, and crushed pretzels.
Step 4: Add the Top Layer
Add another handful of marshmallows and candies on top for extra color and gooey texture once baked.
Step 5: Bake the Bars
Bake for 15–20 minutes, or until the marshmallows are golden brown and the chocolate has melted into gooey perfection.
If you prefer extra gooey bars, remove them slightly earlier — for firmer, chewy bars, bake the full 20 minutes.
Step 6: Cool and Cut
Let the bars cool completely before cutting (this helps them set and makes slicing easier).
Once cool, drizzle with melted chocolate or caramel if desired.
Cut into squares or rectangles — and get ready for sweet, sticky chaos in every bite.
