S'mores Dump Cake


Who doesn't love a gooey s'more in the summer, with a perfectly toasted marshmallow and melted chocolate all sandwiched between two graham crackers? Nothings better. This dump cake is exactly that but add some moist chocolate cake, a layer of chocolate pudding, and some marshmallow fluff in there too...

Just to make it truly irresistible!

Dump cakes have always sounded amazing to me and this one certainly does not disappoint. It's sweet, rich, and oh so chocolatey. I also love how moist they are because let's be honest, there's nothing worse than a dry cake. This chocolatey cake will give you that glimpse to summer nights that we're all currently counting the days until. As if that's not enough, it's ready in just over 1 hour.

It is a s'mores cake after all so an extra large serving of marshmallows is absolutely critical. As always, mini marshmallows are the tastiest in my opinion and work perfectly for this recipe. These mini marshmallows will be the finishing touch before popping your cake into the oven. This way, they will be the top layer and have the opportunity to get beautifully golden and toasted (giving you the illusion of a marshmallow that you roasted over a fire, of course). There will also be a nice layer of marshmallow fluff in there too, so you're cake will definitely not be lacking in the marshmallow department.

Lay on the layers!

The careful layering of each ingredient is key to this dump cake as well. After making your batter, you'll begin layering by pouring it all in. Then you will add some marshmallow fluff (my favorite part, personally) and smooth this over the batter. It may be a little tricky to spread so if you end up having some dollops of fluff atop your batter that is perfectly fine as well. Then you'll go ahead and add some of the chocolate pudding on top of the fluff (I know right, this just keeps getting better and better). Lastly, you'll finish the layers by sprinkling the crushed up graham cracker pieces on top and then adding your mini marshmallows too. I like to also keep some of the graham cracker pieces a little larger too, adding a nice crunch to your topping!

Cut into 9 equally sized squares and dive in! The perfect super chocolatey, late night, soon-to-be-summer dessert treat.
