Cook the chopped bacon in a medium skillet over medium heat until crisp. Let drain on a paper towel-lined plate.
Preheat oven to 350F.
Place the dough on a large piece of parchment paper. Cover with another piece of parchment and roll out to a 12 inch circle. Remove the top parchment and roll up edges of circle slightly to create a crust edge.
Transfer the bottom parchment with the crust to a pizza stone or a large cookie sheet. Bake 10 to 12 minutes, until the edges are golden brown and the center is beginning to firm up. Remove from the oven.
In a small bowl, stir together the softened cream cheese and the garlic. Spread this evenly over the crust. Top with the mozzarella and cheddar, and sprinkle with the chopped bacon and sliced jalapeño.
Return to the oven and bake another 10 minutes or so, until cheese is melted and bubbly. Let cool 10 minutes before slicing.
