Ingredients in Easy Brownie Mix Cookies
- Brownie mix: Any standard box will work, but stick to the basic fudge brownie variety—nothing with extra mix-ins.
- Egg: Just one is all you need to bind the dough and keep the texture chewy and soft.
- Melted butter: Provides richness and moisture, giving the cookies that decadent brownie mouthfeel.
- Hershey bars: Classic milk chocolate is the perfect topping. Each cookie gets a square that melts into a smooth finish.

Helpful Tips
Full instructions for making the cookies can be found on the recipe card below, but here are a few helpful tips.
- Don’t overbake. Even if the cookies look a bit soft in the center after 8 minutes, pull them out. They’ll firm up as they cool, and overbaking will make them dry instead of fudgy.
- Make it your own. Stir in chopped pecans, espresso powder, or chocolate chips to intensify flavor.
- For a bakery look: After topping with chocolate, swirl a little with an offset spatula or spoon to get that glossy, melted-chocolate finish.

Storage Instructions
- Store in an airtight container at room temperature for 3–4 days.
- To freeze, let cool completely and layer between parchment in a freezer-safe bag. They’ll keep well for 1–2 months.
- Reheat briefly in the microwave for gooey, melty magic all over again.


FAQs
Can I use a different chocolate for the topping?
Absolutely. Dark chocolate, mini Reese’s, or even a scoop of Nutella would all work well. Just choose something that melts easily.
Do these freeze well?
Yes! You can freeze the cookies after baking and topping. Just let them cool completely, layer between sheets of parchment, and store in an airtight container for up to 2 months.
What if I want a thinner, crispier cookie?
Use a second egg instead of one, and reduce the butter to 1/3 cup. This will thin the batter slightly and create crispier edges.

They taste great so I gave it 5 stars but I’m guessing user error because mine came out super flat 🤷🏼♀️
Where did I go wrong!?!? Lol
Nellie says
If your cookies are spreading too much, you can try chilling the dough for about an hour before scooping and baking – many times that solves the problem!

What size Brownie Mix ?
Penny Messner says
How long does it take for the chocolate to set?
Nellie says
It shouldn’t take more than an hour, but you can speed it up if you put it them in the fridge for a few minutes!
