These Gooey Oreo Brownies could probably be called my signature, go-to dessert. I make these whenever my husband needs something sweet or when I’m supposed to take a dessert somewhere and run out of time to either create a new recipe or make something complicated. And no one ever complains when I show up with them again; in fact, they celebrate, because the brownies are really stinkin’ good.

What I’m saying is these Gooey Oreo Brownies are 3 things: easy (like ridiculously simple), delicious, and gone in just a few minutes everytime. 


A boxed mix; for real??


Yep. Sometimes I make desserts completely from scratch (re: Brown Butter Banana Bars with Caramel Icing or Cranberry White Chocolate Bars).  But, sometimes, life is crazy, my one year old is screaming and refusing to be put down, my house is in shambles, and I just don’t have time to bake and clean up a bunch of ingredients (re: 5 Ingredient Lemon White Chocolate Cookies).  

These brownies are one of those house-is-in-shambles-this-is-all-I-can-manage desserts that is still out of this world amazzzzing. 




Making the Brownies


To start, buy yourself 3 things: a box of brownie mix, a package of Oreos, and a bag of large marshmallows. 

Then, make the brownie mix by following the directions on the back of the box (so you probably need some oil, a couple eggs and water). 

Spray a pan or line it with foil and spray it. Pour half the brownie batter into the bottom and spread it evenly.  Place Oreos in rows: 4 rows with 5 Oreos across in each row. 

Rip your marshmallows in half and put a half marshmallow in between each of the Oreos.

Top with the rest of the batter. I usually just spoon and drizzle the batter over the top so it covers it. (You will still see bits of Oreo and marshmallow – that’s okay, because the brownies will puff up as they bake).

Bake them according to the brownie box directions. Let cool completely before cutting, because the marshmallow makes them really gooey (but in a really good way). 





Step It Up a Notch


If you want these brownies to be over-the-top-ridiculous, make some Oreo icing to go on them. Let’s make this easy: buy a can of cream cheese or fudge frosting. Crumble/crush about 6 Oreos and stir into the frosting. Spread over brownies and then tell me how much you love me! Ha.
