Preheat the oven to 350 degrees F (175 degrees C).

Beat sugar, butter, cream cheese, and pudding mixes together in a bowl. Beat in eggs, one at a time, and beat well after each addition. Add vanilla extract.

Sift flour, cocoa, baking soda, and salt together in a separate bowl. Add to sugar mixture and beat until blended.

Drop dough by large spoonfuls onto ungreased cookie sheets. Sprinkle the top of each cookies with sprinkles before baking.

Bake in the preheated oven until edges are set, 12 to 15 minutes. Be careful not to overbake; cookies will get too hard and chewy.
