Preheat oven to 350 degrees and line 18 cupcake cups with liners (foil liners recommended). If using paper liners, spray liners lightly with cooking spray before filling with batter.
In a large mixing bowl, beat yogurt, eggs and vanilla until well combined. Stir in pumpkin and cinnamon. Slowly add flour, sugar, baking soda and salt, stirring until well combined. Fill liners 1/2 full with batter.
To prepare raspberry cream cheese, beat softened cream cheese with sugar until well combined. Stir and smash raspberries into cream until combined and berries broken down. Place 1 teaspoon raspberry cream on top of filled cups. Take a toothpick or skewer and swirl cream throughout batter. Bake for 28-33 minutes, or until baked though. Remove and let cool. Serve room temperature or chilled.
