Place 1/2 of the cream cheese in a large mixing bowl.
Beat the cream cheese with the paddle attachment until smooth.
Add in the granulated sugar, peanut butter, and 1/2 teaspoon vanilla and mix until smooth.
Stir in 1/4 cup of the yogurt.
Transfer the mixture to your serving bowl.
Place the remaining cream cheese in the same mixing bowl and beat until smooth.
Stir in the brownie mix & 1/2 teaspoon vanilla on low.
Increase the speed and beat until smooth.
Stir in the remaining 1/4 cup of yogurt.
Add this mixture to your serving bowl.
Pour in the mini chocolate chips and use your spatula to swirl the two dips and the chocolate chips together - do not fully mix- you want the swirl.
Serve with assorted dippers like cookies, fruit and graham crackers.
