Yes, That’s What I Said. Party Brownies!

My sister Kristin has been making these fudgy, sprinkly, crowd-favorite brownies all summer, and I’ve sent her 100 texts to get all the info on this recipe over the last few weeks because I am obsessed with these babies.
Kids love them, adults love them, they’re easy, they’re fun, and they disappear alarmingly fast. They’re PARTY BROWNIES!
The base: a box of brownie mix. I don’t feel bad about this in the slightest. It makes these perfect “party brownies” because you can throw them together at a moment’s notice with minimal effort.
The top layer: an old-fashioned-style chocolate fudge frosting. The kind with the dry, crackly exterior, the kind my mom puts on my dad’s birthday cake every year, the kind that everybody’s grandma has a recipe for somewhere in an old stained church cookbook. It’s so good and it’s the exact top layer I never knew my brownies needed.
I call these party brownies because there is an event to bring them to nearly every weekend.
A pool party at my parents’ house, Bjork’s extended family reunion, an impromptu hangout with friends – the answer to all scenarios is a pan of Party Brownies. ♡

How To Make This Recipe
1
Make Brownie Mix.
I give you permission to use a box of brownie mix. Ghirardelli Double Chocolate is our house favorite. (affiliate link)

2
Make The Frosting / Icing / Fudge Top Layer.
Boil your butter, milk, and sugar for a good 45 seconds. SET A TIMER! We don’t want to over (or under) cook this.

3
Pour Frosting On Brownies.
Add chocolate chips to the boiled frosting and pour immediately over the brownies. It’s going to want to set fast, so let’s go, chop chop, no checking Instagram right now!

4
Add Sprinkles!
Add them to the frosting immediately before it sets!

5
You’re Done. Yum.
LIKE SERIOUSLY REALLY YUM.

These brownies are FABULOUS!!! Everyone I have shared them with loves them!!!
