Preheat oven to 375°F. In a medium skillet over medium-high cook bacon until crisp. Drain bacon; reserve 1 tablespoon grease.
Add peppers and minced garlic to bacon grease. Cook and stir until peppers are just tender.
In a large bowl beat cream cheese and sour cream until smooth. Stir in bacon, jalapeño mixture, and ⅔ cup of the shredded cheese.
For each cup, gently fold one pastry sheet in half. Fold in top corners to middle, forming a point. Fold bottom corners to middle, forming a point. Place folded dough in muffin tin, forming a cup. Repeat with remaining sheets.
Fill phyllo cups with cream cheese mixture. Sprinkle remaining cheddar cheese over cups.
Bake 7 to 8 minutes or until heated through. Remove from pan and sprinkle with cilantro.
