The Best Box Brownie Recipe

The best box brownie recipe starts with a fudge brownie box mix but then Oreos, a chocolate bar, coffee, and a magic ingredient are added to the batter before baking. 🍫⁠

I love these fudgy box brownies because kinda homemade but not all the way is my favorite kind of recipe (and yours too 😄)⁠

I've been trying to make the PERFECT brownies for years. And I've had a hard time getting it juuuuuust right.

But I did it! This is our favorite brownie recipe right now.

They are stuffed with Oreos, a chocolate bar, coffee, and a splash of vanilla! So it's boxed brownies but not quite. You'll love these. Your family will love these. Your neighbors will REALLY love receiving a freshly baked tray of brownies on their doorstep 🤩

Ok, I'm in! What do I need?

• A mixing bowl and measuring cups
• A whisk and a spatula to make sure you get allll of the batter out.
• A baking pan. I like this size.
• Parchment paper sheets to make it easy to take the brownies out of the pan.
• A glass of milk 😁

What dessert should I make next?

You have to make these chocolate chunk cookies and then these summer sugar cookie cups. SO GOOD!
