In the bowl of a mixer, combine the cream cheese, butter, peanut butter, brown sugar, powdered sugar, vanilla extract, and salt. Whip with the paddle attachment until fluffy. Add the peanut butter chips and chocolate chips and stir to combine. Using a spatula, shape the mixture into a football shaped oval on a platter. Cover with additional mini chocolate chips and use the white chips to make laces. Serve with pretzels or animal crackers.
