Besides, I think that when we first posted them, our blog was just starting out and probably our only reader was our mom.
The story behind mom’s Famous Marshmallow Brownies
I had to put “Famous” in the title because our mom is seriously famous for these amazing brownies.
When we were growing up, our mom would make these brownies all the time, but it was usually for someone’s birthday, for a sick friend, or a neighbor that just had a new baby.
When mom did make a pan just for our family, it was always a special treat. And we could eat the whole pan in a matter of hours.
I now make these brownies quite a bit because they are easy and it makes a TON so they are perfect to share with neighbors, or take to a potluck party.
Or eat the whole pan if you feel like it. I won’t judge you.

How to make Marshmallow Brownies
Step 1: In a medium size bowl, mix together softened butter, sugar and cocoa until well combined.
Step 2: Add the eggs to the mixture one at a time, and blend until smooth.
Step 3: Add flour, salt and vanilla and continue to combine until everything is fully mixed.
Step 4: Grease a cookie sheet (half sheet size) with non stick cooking spray. Pour the brownie batter into the pan and spread out with a greased spoon or knife.
Step 5: Bake for 22-25 minutes at 350 degrees.
Step 6: Remove from oven and spread an entire bag of mini marshmallows over the hot brownies. Be sure to cover up as much brownies as you can. Place the brownies back in the oven for 3 minutes.
Tip: Do not cook for longer than 3 minutes or your marshmallows will burn and be crunchy. You want your marshmallows to be soft and not chewy.
Step 7: Let brownies cool completely before frosting.
Step 8: Cover the brownies with chocolate frosting. For a homemade chocolate frosting recipe, read below. We have just the right amount of all the ingredients to make your frosting perfect.
How to make Fail-Proof Chocolate Frosting
Homemade frosting can be a little tricky. I could never get it right at first, then I came across this recipe, and ever since then, I haven’t had a problem with my frosting. It comes out perfect every time! Here is how you make it.
The key is to follow the ingredients measurements perfectly and in the right order. It’s also important your butter is at the right consistency.
Step 1: Soften your butter. This does not mean melt. This means room temperature. If you are in a hurry, and just got the butter out of the fridge, cut it into centimeter width slices and microwave for 15 seconds.
It’s okay if there is a little bit of melted butter at the bottom of the bowl, but you do not want to melt all of the butter or your frosting will be thin and end up looking like more of a glaze than frosting.
Step 2: Add the milk, vanilla, cocoa and powdered sugar to the bowl. Add them one at a time and continue to mix with a hand mixer.
We find that the powdered sugar and cocoa combines best without lumps when you use a hand mixer. You could also use a whisk, but to save yourself some time and an arm workout, we definitely recommend a hand mixer.
If the frosting isn’t to your desired thickness, you can also add a little more powdered sugar. Remember that you can always add more, but you can’t always take it back. You will want to start small with the powdered sugar and add a little at a time.
Step 3: Mix until the frosting is smooth.
Step 4: Spread over the cooled marshmallow brownies. It’s important to let the brownies cool before adding the frosting or else the frosting will melt and become more of a glaze.
