I’m going to let you in on a little secret today. Well, it’s really not a secret and you might have already figured it out if you read my blog posts regularly. My Mom is my best friend. She’s an amazing woman and she’s my “person”. She gets me. She doesn’t judge me. She listens. She supports. She’s that person in my life that all of you wish you had in your life and I hope you do!
She’s so cool that my friends have often told me they love her too because of her kindness and love that’s she’s shown them over the years. She was that mom that would bake you and your friends cookies in high school at 10 pm because you asked and she rocks. True story.
My mom also rocks in the kitchen. This is where I get my talent from. She’s a recipe follower though and I think I stress her out just a little when I start throwing things in that aren’t called for on the recipe. Over the years she’s learned to look the other way when this happens and try to trust me.
There are some recipes that I don’t dare alter and today I’m sharing with you one of those. This is my mother’s secret weapon. The treat that everyone begs for. This is how my family bribes teenagers to come out and “rock pick” in the spring. The promise of my mom’s Fudgy Marshmallow Brownies. I’m telling you these treats have powers. I’m thinking if you are trying to snag a guy he will propose after one bite. I actually have no doubt in my mind that he will! 
Today I’m bringing you these fabulous brownies plus I’m partnering with Bon Appetit and Epicurious to talk about the importance of face-to-face time in the kitchen. I love to spend time with my family in the kitchen weather it be my mom, Miss K, or other family members. I find it a great way to connect and bond with them. I remember licking the spatula and giggling over stories with Mom growing up and Miss K is quickly learning to grab the spatula and follow in my footsteps. I can’t wait to create long lasting memories between Miss K and I plus Grandma while making treats!
Currently one of our favorites spots to create memories in the kitchen is at our cabin. We are up there a lot throughout the summer and everyone pitches in to help with meals. I usually head up the main dishes with Mom assisting then Grandma and Miss K are on clean up duty! It’s so fun to watch my mom and Miss K interact while doing dishes. Miss K is talking a mile a minute nodding her head and making hilarious facial expressions and my Mom is giggling. These are memories I’m going to cherish the rest of my life and I’m pretty sure they are too!
{Dad & Mom – Thank you for everything you’ve done for me in life! Dad you are always there to sample my treats and offer your support. Mom you have been there in ways every girl dreams their Mom will be. You two are my rocks.}

Denise says
These brownies are delicious! My husband loves them!
Julie says
Great! I’m so glad they are a hit!
Jean says
Not sure what the deal is with the frosting. It’s just a runny greasy mess. Are measurements correct? Seems like an awful lot of sugar compared to the small amts of dairy. Idk. Probably won’t be doing this again.
Julie says
The measurements should be correct – I’m sorry to hear that, I haven’t had this issue. Did you bring the mixture to a boil before adding the stirring in the chocolate chips?
Nancapam says

Julie says
Thanks for pointing that out!
Saad Ahsan says
How many cups of sugar do we have to add in the frosting
Julie says
1 1/2 c. white sugar
JULIE says
Verifying butter.. it looks like a whole stick which is 8 Tbsp or is 6 Tbsp correct?
Julie says
6 Tbsp is correct.
Carol Ann says
Do you think I could make these with a graham cracker crust under the brownie mix? I’m thinking about Smores.😁
Julie says
I haven’t tried that but it sounds intriguing! If you try it, let me know how it goes!
Patty says
I don’t have any half and half……can I use milk for the topping? Also, I only have regular size marshmallows. I think I’ll try cutting them up in smaller pieces….will that work okay?
Julie says
Whole milk might work, I haven’t tried it though. The marshmallows should work out.
Joyce M Voltaire Huertas says
What size pan do you use to bake the brownies?
Julie says
A 9×13 pan
Megan says
Absolutely delicious! I’ve made these several times, I have the frosting down, now! One time I don’t think I was letting the sugar “boil” before setting the timer, more of a simmer.
My only suggestion is make sure to do a rolling boil for a full minute, so you get to that soft ball stage to get the firm set on top of the frosting.
My hunny just made brownies, because I’m feeling yucky, but I still couldn’t resist throwing on marshmallows and whipping together some frosting to pour on 🤣 The frosting definitely taste like fudge!
Thanks for passing along a fabulous recipe.
Julie says
You’re welcome! I’m glad you love them!
Rachel says
I just made a batch of these and they were spectacular. My family went absolutely crazy for them. I let the marshmallows cool before adding the chocolate glaze and they came out perfectly gooey with distinct layers. I’ll DEFINITELY be adding these to the rotation! Thank you! (My family was especially grateful for something new and unexpected during lockdown!)
Julie says
I’m so glad to hear that, Rachel! Thank you so much for sharing!
Denise says
I just made these, but we won’t eat them until after dinner. However, I wanted to ask if you spread the marshmallows out or let them be after they are puffed up? They sure look and smell good. My husband wanted to get ice cream, but no room in freezer so next time!
Julie says
I typically leave the marshmallows alone after they have puffed up!
Danielle says
These look delicious! Do you use mini marshmallows?
Julie says
Yes, hope you enjoy them!
Cindy Brown says
Absolutely delicious!!
Julie says
They are, aren’t they!? Glad you enjoyed them!
Laura M Denison says
my chocolate topping mixed in with the marshmallows when I pored it on, What did I do wrong?
I was still very good just not pretty
Julie says
The marshmallows were maybe still too soft from the oven – next time let them cool a bit first and then pour on the chocolate topping. I’m glad you still enjoyed them!
Amy says
Mine did too:-( I should of read this comment before I poured it on lol
Julie says
Oh shoot! At least you still get all the chocolate-y marshmallow-y flavor!
Nicole says
When you say white sugar, do you mean powdered or granulated?
Julie says
Granulated
Grace says
Actually a question. .
Are these served warm right away? Or can they be made in advance and served room temp?
Julie says
They are delicious and gooey served warm but they are also great served later after they have cooled.
