Before we get to the recipe, let’s answer a frequently asked question (FAQ) about brownies:
How do you make chewy brownies not cakey?
To make chewy brownies, use a fudge brownie mix. You can use Betty Crocker brownies with marshmallows or any other of your favorite boxed brownie mix for this recipe. But, if you want chewy brownies, get the fudge mix.

Heart Brownies with Marshmallows paired with Celebrating Valentine’s Day: My Special Valentines Children’s Book
For our brownies with marshmallows pairing, we chose the children’s book, Celebrating Valentine’s Day: My Special Valentines (Learn to Read-Read to Learn: Holiday) by Kimberly Roark and illustrated by Melissa Iwai.
Since we used heart brownies for a Valentine’s theme, the book worked well for us!
In this book, children are introduced to when Valentine’s Day is and what it’s about.
The little girl in the book goes through each person and group she is giving a Valentine to and why.
From the book:
A young girl makes Valentine’s Day gifts for family and friends and tell why they are her Valentines. Special Valentine’s Day activities for children are included in the back of the book.
The reason that I like this book so much is that it teaches children to come up with something special about each person they are giving a Valentine.
We live in such a “do it because we have to” age that we’ve become almost immune to thinking about why we do things.
This is a great book to pair up with your kids giving out Valentine cards and also asking them to say one nice thing about everyone they are making a card.
It’s a fantastic conversation starter!

Recipe for Brownies with Marshmallows
- 1 box of fudge brownie mix (+ ingredients to make the brownies)
- 9-12 large heart-shaped marshmallows
- Preheat the oven to 350 degrees. Grease a 9×9″ glass baking pan with cooking spray.
- Prepare brownies according to package direction and pour into baking pan
- Before baking, place marshmallow hearts on top of batter. You will have 3 columns of 3 hearts, or 4 columns of 3 hearts (depending on how you place them). Remember to space them far enough apart so that they don't melt into each other.
- Push the marshmallows down gently into the batter (but do not cover with batter).
- Bake brownies for 35 minutes (or according to package directions). If marshmallows start to get too brown before the brownies are baked, place a piece of aluminum foil over the top until the end of the baking time.
- Cool completely before cutting into squares around the hearts.
