Take cream cheese out so it'll soften. (Come back in 30 minutes if you're just taking it out of the fridge now.)
Dice 4 oz of strawberries; add the sugar; mix, and set aside.
Add remaining strawberries into a food processor and process until pureed. (Don't clean out food processor bowl.) Transfer puree into a mixing bowl.
Place cream cheese, powdered sugar, and vanilla into the processor; process until smooth.
Add cream cheese mixture to the purred strawberries; stir to combine.
Fold in the yogurt until well combined and no streaks remain.
Top the dip with the sliced strawberries; serve with graham crackers, vanilla wafer cookies, Oreos or fruit.
