In a large bowl, or stand mixer, beat together cream cheese and butter, until light and fluffy (about 1 to 2 minutes)
Slowly beat in the 2 1/2 cups of powdered sugar and 2 Tablespoons of milk, until creamy. Add cocoa powder, brown sugar and vanilla. Beat until creamy and smooth, or until it reaches your desired consistency. (You can add 1 more Tablespoon of milk, if needed)
Serve dip with strawberries, vanilla wafers, pretzels, marshmallows, or whatever your heart desires! Enjoy!
