Gooey butter cake is a St. Louis staple. In this version, we prepare a smores gooey butter cake with chocolate, marshmallow, and Graham crackers that makes a perfect dessert to make on your smoker but is just as delicious when made in your oven.
In a bowl mix together the chocolate cake mix, 1 beaten egg, and melted butter. Mix together until smooth.
Spread the chocolate butter cake crust on the bottom of a greased 9x13 pan. Spread to all of the edges and corners.
Spread the marshmallow fluff on to of the chocolate layer.
In a bowl combine the powdered sugar, vanilla, and 2 eggs. Beat together until combined, then beat in the softened cream cheese.
Spread the cream cheese layer evenly over the marshmallow layer. Add the marshmallows to the top of the dessert.
Preheat your oven or smoker to 350 degrees. Bake the Gooey Butter Cake for 40-45 minutes turning half way through. The center may still have a little giggle but the edges should be set.
Remove the gooey better cake for the oven or smoker. Sprinkle the crushed Graham crackers on top of the dessert and allow to cool fully before serving.
