If you’re the kind of person who thinks brownies should be rich, fudgy, and loaded with fun toppings, these Marshmallow Cocoa Puff Brownies are about to become a new favorite. They start with a chocolatey brownie base, then get topped with gooey marshmallows and crunchy chocolate cereal for a dessert that’s equal parts nostalgic and irresistible.
What I love most about these brownies is the texture. You get that dense, chewy brownie layer on the bottom, a soft marshmallow middle, and a crispy chocolate crunch on top. They’re the kind of treat that disappears quickly at parties, bake sales, and family movie nights, so you might want to make a double batch.

How to Make Marshmallow Cocoa Puff Brownies
Step 1: Prepare Your Baking Pan
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
Step 2: Make the Brownie Batter
Prepare your favorite brownie batter according to the recipe directions or package instructions. Pour the batter evenly into the prepared baking dish.
Step 3: Bake the Brownies
Bake until the brownies are almost fully cooked, usually a few minutes less than the recommended baking time.
Step 4: Add the Marshmallows
Remove the brownies from the oven and immediately sprinkle an even layer of mini marshmallows over the top.
Step 5: Finish Baking
Return the pan to the oven and bake for a few more minutes until the marshmallows become soft and puffy.
Step 6: Add the Cocoa Puff Layer
While the brownies cool slightly, prepare a simple chocolate coating and gently toss the chocolate cereal until evenly coated. Spread the cereal mixture over the marshmallow layer.
Step 7: Cool Completely
Allow the brownies to cool completely before slicing. This helps the layers set and makes cutting much easier.
Step 8: Slice and Serve
Cut into squares and serve. Enjoy the combination of fudgy brownies, fluffy marshmallows, and crunchy chocolate cereal in every bite.
