1 (18.25-ounce) package chocolate cake mix

Heat oven to 350 degrees (325 convection) and prepare and 9-inch round cake pan.
Combine the cake mix, 1 egg, and 1 stick melted butter, and stir until well blended. Pat the mixture into prepared cake pan and set aside.
In a stand mixer on medium speed, beat the cream cheese until smooth. Add the remaining 2 eggs, and the cocoa powder.
Lower the speed of the mixer and add the powdered sugar. Mix until everything is well combined. Slowly add the remaining 1 stick of melted butter and vanilla and continue to beat the mixture until smooth.
