In the bowl of a stand mixer fitted with the whisk attachment, beat the heavy cream, vanilla, and powdered sugar on medium-low for 1 minute. Slowly increase the speed to medium-high and mix until stiff peaks form.
Add the greek yogurt and mix for 20 seconds on medium or until thoroughly combined.
Place the cream mixture into a piping bag * and pipe the cream into the individual mini pillow shells.
Top with chopped fresh fruit.
Serve immediately or keep in the fridge in an airtight container until ready to serve. Best served within a few hours.
*Not necessary. You can just spoon the cream into the shells if you'd like. The piping bag just made it easier for me. Note, the nutrition facts do not include the fruit.
