In a mixing bowl or stand mixer, whip the heavy cream until stiff peaks form.
In a separate bowl, beat the softened cream cheese and slowly add the powdered sugar and vanilla, mixing until smooth.
Fold the whipped cream into the cream cheese mixture. (Or use pre-make Philadelphia No-Bake Cheesecake Filling)
Cut the store-bought pound cake into 1-inch cubes and slice the fresh strawberries.
Add half of the pound cake cubes to the bottom of a trifle dish or large clear glass bowl, then top the cake layer with half of the cream cheese mixture. Add half of the raspberries, strawberries, and blueberries over the creamy filling. Repeat the steps, then refrigerate until ready to serve.
