Sprinkle the yeast and brown sugar over warm water in the bowl of a stand mixer fitted with a dough hook. Let stand 5 to 10 minutes until the yeast softens and begins to form a creamy foam.
Turn mixer to the lowest setting and slowly add 2 cups flour 1/2 cup at a time. Add salt, onion powder and 1/4 cup butter. Integrate the remaining 2 cups flour and knead until dough is smooth and elastic, around 5 to 7 minutes.
Coat a large bowl with 1 tablespoon of olive oil. Shape the dough into a ball and place in the bowl, turning to coat all sides with oil. Cover the bowl with a towel and let rise in a warm area until dough has doubled in size, around 45 minutes. Punch down dough and allow to rest for 20 minutes.
Meanwhile, cook the bacon on a skillet on medium heat until crispy and brown, around 10 minutes. Transfer to a plate lined with paper towels.
Cook the onion and garlic in the bacon drippings until transparent, around 5 minutes. Season the onion mixture with the cumin, oregano and black pepper. Add in the cream cheese and yogurt until smooth and spreadable.
Preheat the oven to 400°F. Grease a 12 inch cast iron skillet.
Press the dough into and up the sides of the cast iron skillet. Spread the cream cheese mixture evenly over the pizza. Sprinkle the cheeses over the pizza and arrange the jalapeno slices on top. Crumble the bacon over the pizza.
Bake on the bottom rack of the preheated oven and cook for 35 minutes or until the crust is golden brown. Remove and let sit for 3 to 5 minutes before slicing.
