These marshmallow brownies are a combination of a fudge brownie, gooey marshmallow and chocolate frosting, guaranteed to satisfy any chocolate craving.
The Best Combo Ever!
Chocolate and marshmallow is pretty much one of the best combos ever. One of my favorite childhood treats was to get a bowl of vanilla ice cream, cover it with chocolate syrup, and then add in a handful of marshmallows. Heaven in a bowl. These brownies remind me of that favorite childhood treat
These brownies are made with a fudgy brownie base that is topped with marshmallow and then covered with a delicious chocolate frosting. Layers of yummy goodness that will quickly become a favorite dessert.

For the Chocolate Frosting You Will Need:

Brownie Tips and Tricks
Line your 9 x 13 pan with parchment paper to make it easier to remove brownies from pan.
Don’t overbake your brownies. You want them soft and fudgy.
How to Cut Marshmallow Brownies
Because of the warm marshmallow layer, they can be tricky to cut. They are more difficult to cut when they are warm but they are so yummy warm! So if you don’t care what they look like, just grab a serrated knife and cut into them right out of the oven. They will taste like heaven, but they won’t be very pretty. If you would like a nice clean cut, refrigerate them first and then cut. You can serve them chilled or room temperature.
Frequently Asked Questions
They can be kept at room temperature for up to 3 days but they will last a few days longer if kept in the refrigerator. Eat them chilled or at room temperature. frozen in an airtight container for up to 3 months.
To freeze them: Place sliced brownies on a cookie sheet and freeze. Once they are frozen, put them into a freezer safe zippered storage bag or airtight container and freeze for 2-3 months..
If you want to skip making the brownie part from scratch you can definitely use a brownie mix. Make sure it is one that is for a 9 x 13″ pan. Follow the directions on the back of the box. Pull the brownies out of the oven 5 minutes before the end of the cook time to add the marshmallow layer.
What Can You Put on Top of Brownies?
Peppermint Brownies. During the holidays I like to dress them up and use peppermint extract instead of vanilla and sprinkle the top of the frosting with crushed candy cane. You could also use peppermint flavored marshmallows if you can find them.
Peanut Butter Brownies. Drizzle some melted peanut butter over the top of the marshmallow layer before adding the frosting.
S’mores Brownies. Sprinkle the top of the marshmallow layer with some crushed graham crackers or graham cracker crumbs.
Candy Bar Brownies. Cut up your favorite candy bar and add sprinkle over the top of the frosting layer.
Rocky Road Brownies. Add chopped nuts to the brownie layer, or sprinkle them on top of the marshmallow layer or add them to the top of the frosting.

This is a fantastic recipe. My family loved the combination of chocolate with marshmallows. Really excellent. I was wondering what type of cocoa you like to use. I used Hershey’s, but I know some recipes call for Dutch processed. I’m not sure how much the flavor changes with the different cocoas available. Thank you! Bridget Marie

I usually have Dutch processed on hand but have also used Hershey’s and both work fine – so glad you enjoyed the recipe!
