Let the cream cheese (or coconut cream) sit at room temperature for about 15-20 minutes.
In a mixing bowl, combine the softened cream cheese and yogurt or nut butter, then beat until smooth and creamy for 2-3 minutes.
Add the pure vanilla extract and sweetener, mixing until fully combined. Adjust sweetness to taste.
Slowly add the brownie mix or cocoa powder while mixing to avoid clumps, until well combined.
Chill the dip in the refrigerator for about 30 minutes, if desired, then serve.
Spoon the dip into a serving bowl and arrange dippers around it.
