Preheat your oven to 400°F. In a big bowl, mix together the cream cheese, pepper jack, and garlic. Add a pinch of salt and pepper for flavor.
Cut the jalapeños in half lengthwise, and use a spoon to scoop out the seeds and veins. Fill each jalapeño half with the cheese mixture, then wrap each one with a halved slice of bacon.
Arrange the wrapped jalapeños on a baking sheet and bake until the bacon turns crispy and the peppers become tender, which takes about 35 to 40 minutes.
