In a large skillet, sauté the chopped bacon until crispy and browned, about 8-9 minutes. Using a slotted spoon, remove the cooked bacon to a bowl.
Pour out the bacon grease in the sink with running warm water.
In the same skillet, add the chopped onion and butter, then season with salt. Saute for 8-10 minutes. Add 1/4 cup water and stir until evaporated. Add the chopped jalapeños and continue cooking until the onions are caramelized, about 10-15 more minutes.
Reduce heat to LOW. Stir in the strawberry preserves and cooked bacon. Remove from heat and set aside.
Toast the burger buns. Set aside.
In a large skillet over medium high heat, add butter or olive oil to grease the skillet.
Add a few jalapeños slices and burger patties. Season with salt. Place a square of parchment paper on top, then smash as flat as possible. Cook for 1 minute, then flip and add sliced havarti cheese to cook another 2-3 minutes.
Layer the bottom of the toasted burger buns with softened whipped cream cheese, then the cheese smashburgers and bacon jam to sandwich with the top toasted bun. Enjoy warm!
