Raise your hand if you love ooey, gooey, fudgy brownies. Yep, me too. I love them so much that I turned the dial and totally took things to the next level with these Dulce de Leche Swirl S’mores Brownies. Basically I put all of my favorite things in one brownie and called it a day.

These aren’t my first time creating a s’mores brownie dessert mashup! My Cherry Cola S’mores Brownies and Peanut Butter Cup Stuffed S’mores Brownies are some of my most decadent and delicious brownies to date. And friends, these Dulce de Leche Swirl Brownies include my homemade dulce de leche made from sweetened condensed milk. So, so good!

A base of graham cracker crumbs is topped by One Bowl Chocolate Fudge Brownies before dollops of dulce de leche are plopped onto the brownie batter and then swirled into it to insure that each bite is as decadent as the one prior.

I might have then gone a little overboard as I thought a handful or two of chocolate chips on top of all of that was a good idea.

(For the record, I was right.) Into the oven this pan of heaven goes and when it’s done, it’s topped with clouds of marshmallows – a whole bag! – and then broiled to the perfect shade of char doneness.

How to Make Dulce de Leche Swirl S’mores Brownies

[1] In a medium bowl, add graham cracker crumbs, sugar, salt and butter.

[2] Stir together to fully combine.

[3] Pour into greased 9″ x 13″ baking pan.

[4] Press crumbs into an even layer and bake for 12-14 minutes at 350 degrees or until set and beginning to brown.

[5] Prepare batter for brownies and pour over graham cracker crust, spreading into an even layer.

[6] Add dollops of dulce de leche on top of brownie batter

[7] Swirl dulce de leche into brownie batter with knife or skewer to create marbleized effect.

TIP: Be careful to not drag your knife or skewer too deeply through the batter or you’ll disturb the graham cracker crust.

[8] Sprinkle chocolate chips over the swirled batter. Bake for 18-20 minutes at 350 degrees or until just set.

[9] Remove brownies from oven and turn oven to broil setting. Add marshmallows to top of brownies pressing lightly to adhere them to the warm brownies.

[10] Broil for 2-3 minutes or until they reach desired char level. Let cool completely before attempting to cut and serve.

TIP: Don’t walk away from your oven and watch your brownies closely as the marshmallows will brown quickly!
