Rich and chewy marshmallow brownies made with only seven ingredients and then topped with gooey marshmallows. These are as good as the box mix – seriously!

As long as I can remember, people have been using the brownie recipe from a cardboard box if not making it from scratch like these blonde brownies. But what if I told you that homemade brownies are *almost* just as easy and, dare I say it, even better than the box version.
Our family has been making brownies from scratch for years and I am completely honest when I say that I’ll never go back to the box again. These chocolatey rich and chewy brownies only require 7 simple ingredients (no dextrose or artificial flavors here!) and they are naturally oil free.

In just a little more time than it takes to mix brownies from a box (maybe 6 minutes instead of 4?) you will have a pan of homemade chocolate heaven ready for the oven. Broil on your favorite toppings and serve with vanilla ice cream for a special summer treat.
Ingredients

The 7 ingredients needed to make these brownies are really simple
- butter
- sugar
- cocoa powder
- salt
- vanilla
- eggs
- flour
How to Make Marshmallow Brownies

To begin, preheat your oven to 325˚F. Combine the first four ingredients in a bowl and microwave them for 1 minute. Stir it all until the butter is melted and the mixture is smooth.

Add the eggs, one at a time. Stir after each one until you can’t see the egg anymore.

Stir in the vanilla, and then add in the flour all at once and stir vigorously until you can’t see the flour any longer.

Coat a 13×9 pan with cooking spray and spread the brownie mix evenly into the pan. This beaut is ready for the oven!

Bake the brownies for about 30 minutes or until a toothpick inserted into the center barely comes out clean.

These brownies were AMAZING! I just made them plain this time but will be trying them again with your suggested optional ingredients. I haven’t made brownies from a box in many years, but this recipe has now replaced my previous made from scratch recipe. So yummy and easy and chocolatey!
So glad you enjoyed it! I agree that it’s an amazing recipe!
