Using an electric mixer on medium speed, beat the cream cheese and butter until throughly combined and smooth. Add the sugar, brown sugar, yogurt, cinnamon, and vanilla. Mix well, making sure the mixture is smooth.
Chill the dip for at least 30 minutes. If chilling for longer than 30 minutes, let the dip sit at room temperature for 10-15 minutes before serving. If desired, garnish with a sprinkling of additional cinnamon.
Serve with an assortment of cookies, graham crackers, pretzels, or apple wedges.
