What could possibly be better than M&M Brownies? How about topping them with marshmallow caramel goodness!! One bite of these Caramel Marshmallow M&M Brownies will definitely satisfy every sugar craving you have.

Marshmallow Topped Brownies

These gooey chocolate brownies have three delicious layers and are the ultimate party brownie. The brownies are fudgy, the caramel and marshmallows are gooey, and the M&M candies give it a delicious color and crunch.

What I love most about these brownies is that you can make them for any holiday using the different holiday M&M's that come out every season. The other thing I love about these brownies is just how easy they are to make. You can literally have a pan of gooey marshmallow brownies on your counter in under 30 minutes. Now I do recommend waiting until they cool off before digging in.

What makes these brownies so amazing is the layer of caramel that is hiding under the toasted marshmallows. It kind of melts and soaks into the brownie layer a little bit while the marshmallows are toasting. It makes the brownies so rich and delicious.

Trust me if you like marshmallows and brownies you need to make a pan of these marshmallow topped brownies ASAP!

Ingredients for Marshmallow Brownies

These sweet and gooey caramel marshmallow brownies only require 5 ingredients. You will also need pantry ingredients that you probably already have to make the brownie mix.

Brownie Mix - Make sure you buy a family sized brownie box mix for a 9x13 pan. You can also make a double batch of these chocolate chip brownies (minus the chocolate chips) if you prefer homemade brownies.
Caramel - You can use 1 cup caramel baking bits or 24 caramel squares.
Milk - Using a little bit of milk will help the caramel melt smoother.
Marshmallows - Miniature marshmallows work the best for this brownie recipe because of the smaller size.
M&M's - I prefer the small miniature M&M's, but any size or flavor of M&M candies will taste great on these brownies.

How to make Caramel Marshmallow M&M Brownies

These gooey marshmallow brownies are quite simple to make because they start with a box mix. This is the perfect brownie recipe for the kids to help make.

Step One: Make brownies.

Mix together the box brownie mix, oil, eggs, and water in a medium bowl.
Pour the brownie batter into a greased baking dish and bake for about 24 minutes. (4 min less than the box directions)

Note: Bake time will depend on what brand brownie mix you use.

Step Two: Caramel & Marshmallow Toppings.

Place the caramel and milk in a microwave safe bowl.
Heat for 30 seconds and stir until creamy. Heat additional seconds if needed.
Remove the brownies from the oven.
Spread the melted caramel over the brownies. Sprinkle the marshmallows evenly on top.
Place the brownies back in the oven for another 3-4 minutes.
Turn on the broiler and toast the marshmallows.

Step Three: M&M candies

Remove the brownies from the oven.
Sprinkle the mini M&M's over the top. You will need to press the candies gently into the toasted marshmallows, so they stick better.
Let the marshmallow brownies cool completely before cutting into squares.

Recipe Tips

Want to make a smaller batch? Use a brownie mix for an 8x8 pan. Only add half the toppings to the baked brownies.
Avoid over baking the brownies because you need to put them back in the oven to melt the caramel and toast the marshmallows.
Stay right by the oven when you are broiling the marshmallow layer. The marshmallows will go from white to brown very quickly. I turned away for just a few seconds and almost burned the whole top of these caramel marshmallow brownies.
Use a wet knife when cutting these brownies. The marshmallow layer will not stick to the wet knife as you are trying to make clean cuts. Dip the knife in water, shake off the excess, and make short cuts. Rinse in between each cut for the best results.
Want to make these for other holidays? Use pastel M&M's for Easter, red white & blue M&M's for 4th of July, or red & green M&M's for Christmas.

How to Store these Brownies

Keep these brownies in a tightly sealed container on the counter for 3-4 days. You can also freeze these brownies in a freezer safe bag or container for 2-3 months. The M&M's may change colors as they defrost.
