Cut the pound cake into 10 slices. Use a small STAR cookie cutter to cut out 10 stars from the center of each slice. Chop the remnants of each slice into small pieces. Set aside.
Place the cream cheese and sugar in a medium bowl. Use an electric mixer to combine them until well combined (1 to 2 minutes). Add the cream and continue to whip until the mixture is soft and creamy.
To assemble, set all of the plastic cups on a tray. Sprinkle a few cubes of pound cake into each cup. Top with a small spoonful of cream and a spoonful of both blueberries and strawberries. Layer again, more pound cake, more cream and more berries, and then place a star-shaped piece of pound cake on top.
Notes
Here is a homemade Lemon Pound Cake recipe - add a little yellow coloring to make it yellow... then you'll have yellow stars!
