Step 2
In a large bowl, beat the cream cheese, confectioners’ sugar and vanilla with an electric mixer until fluffy, 3 minutes. Beat in the yogurt just until combined, about 30 seconds. In a separate bowl, beat the cream until you have stiff peaks. With a large rubber spatula, fold the cream into the cream-cheese mixture. Transfer the filling to the prepared crust and spread it out into an even layer. Cover with plastic wrap and refrigerate until very cold, at least 6 hours or up to overnight. Keep the bars refrigerated until serving.
