Add the cream cheese and heavy cream to a large bowl and beat for 2-3 minutes with an electric mixer until light and fluffy.
Scoop the whipped cream cheese mixture into a pastry bag fitted with a star tip. Pipe cream cheese into the bottom of each cup until about ¼ full, being sure to fill in the corners. Then add a layer of the chopped smoked salmon and one teaspoon of the drained capers.
Repeat this process one more time and then conclude with a final layer of whipped cream cheese and one teaspoon of capers on top. Garnish each cup with a couple chives and serve immediately with crackers. Enjoy!
