Preheat your oven to 350 degrees and line two cupcake pans with liners. Set aside.
Prepare your cake mix per the instructions on the box.
In another medium bowl, add the cream cheese, sugar, egg, salt, and mini chocolate chips and blend on medium speed until fully incorporated.
Fill each cupcake well half full with cupcake batter.
Drop in 1 teaspoon of cream cheese mixture to the center of each cupcake. Top with cake batter.
Bake for 20 minutes or until a toothpick inserted into the center comes out clean.
