Ever since I made the White Chocolate Gooey Bars I knew I wanted to make a chocolate version!

This recipe is so simple and so delicious! I couldn't stop picking at the pan-I secretly always pick at the pan and create another straight line so it's not obvious how much I have actually devoured! 🙂 Enjoy 🙂

Chocolate cake mix base filled with marshmallows, chocolate chips, chocolate marshmallows and condensed milk. These Chocolate S'mores Gooey Bars are extra sweet so a batch goes a long way!

Total Time: 45 minutes
Yield: 9-16 Bars 1x

Ingredients

Scale

1 Box Devils Food Chocolate Cake Mix
1 Stick Softened Unsalted Butter
1 Large Egg
2 ½ Cups of Milk Chocolate Chips
1 Cup of Mini Marshmallows
1 Cup of Chocolate Marshmallows (I bought some at Target)
½ Can of Condensed Milk

Instructions

Preheat oven to 350F & Grease an 8X8 Pan.
Place the cake mix, butter & egg in a large bowl and mix together until combined- you will be left with a thick dough.
Press half of the dough into the prepared pan. Layer the dough with graham crackers, chocolate chips, and marshmallows.
Press the rest of the dough on top of marshmallows then drizzle with condensed milk.
Bake for 25-30 minutes. As tempting as it will look coming out of the oven do your best to let it cool as it will be super gooey! And you could easily burn yourself or make a huge mess!
