Bake the cookies, let them cool, and serve.

What brand of brownie mix is best for these cookies?

For best results, I recommend using Ghirardelli Chocolate Supreme brownie mix. If you can’t find Ghirardelli, I recommend using a Pillsbury brownie mix. I don’t recommend using Duncan Hines or Betty Crocker mixes – the cookies spread way too much. If this is the only mix available, try adding ¼ cup of all-purpose flour to the mix.

Should I use the chocolate syrup that comes in the brownie box mix?

Yes, this will give the brownie cookies a more intense chocolate flavor.

Why do I need to chill the cookie dough?

This step helps the butter solidify and prevents the dough from spreading too much while baking. If the dough spreads, the cookies will be really thin instead of thick and chewy.

Can I use graham cracker crumbs instead of crushed graham crackers?

No. I don’t recommend graham cracker crumbs in place of crushed graham crackers. The crumbs act like another dry ingredient and will soak up moisture from the cookie dough, leading to dry cookies. For best results, use crushed graham crackers.

These s’more brownie cookies are rich and chocolatey with a chewy brownie texture!

Tips!

Make the cookie dough ahead of time! Store cookie dough in an airtight container in the refrigerator for up to 2 days before baking.
These cookies are done baking when the edges are just beginning to set. They’ll firm up as they cool on the baking sheet.

Can I use regular size marshmallows?

Mini marshmallows are perfect because they easily combine with the other cookie ingredients! You can try using regular marshmallows, but cut them into smaller pieces before incorporating into the cookie dough.

Can I make these cookies without butter?

Yes, replace the melted butter with the same amount of vegetable oil.

How do I know when the cookies are done?

The cookies are baked when the edges are set, about 11-12 minutes at 350°F. Let the cookies cool fully before storing.
