Roll puff pastry into a 8" x 16" rectangle. If using store bought pastry, you might need to use two sheets.
Cut pastry into two inch squares.
Place each square into a mini muffin tin. Push dough down so it lines the tin.
Bake in a preheated 375 degree oven for 10 minutes.
Remove from oven. Poke down center of each pastry cup so the dough deflates. Return to oven for an additional 5 minutes.
While pastry is baking, place cream cheese in a bowl. Mix until smooth. Stir in cranberries and jalapenos.
Remove pastry cups from the oven. Place 1-2 teaspoons of filling in each cup.
Increase oven temperature to 400 degrees. Bake filled cups for 15 minutes.
Let cool for at least 10 minutes before removing from muffin tin.
Serve warm or at room temperature.
