Okay, I'll be the first to admit it. Something I tried off Pinterest that looked flawless wasn't so hot looking coming from my kitchen but BOY is it yummy! Anywho, here's the recipe.
Crust::
1 box butter-recipe cake mix
1 egg
1/2 cup (1 stick) butter, melted
Filling::
1 8 oz. package cream cheese, softened
2 eggs
1 tsp. pure vanilla extract
1 16 oz. box powdered sugar
1/2 cup (1 stick) butter, melted
1 cup chocolate chips
Preheat oven to 350 degrees. Light grease a 9 x 13 inch baking pan. In a bowl, combine cake mix, egg & butter with an electric mixer. Mix well. Pat into the bottom of prepared pan & set aside. Still using an electric mixer, beat cream cheese until smooth; add eggs & vanilla. Dump powdered sugar & beat very well. Reduce the speed of the mixer & slowly pour in the melted butter. Mix Well. Stir in the chocolate chips. Pour filling onto cake mixture & spread evenly. Bake for 40-50 minutes (closer to 50 so it's not too ooey & gooey). You want the center to be a little gooey, so don't let it stay in too long. Remove from oven & allow to cool completely. You can add chocolate & drizzle it on top after cooling for 15 minutes. Allow to cool for at least an hour & then cut into bars and enjoy!
