Heat a heavy-bottom skillet over medium-high heat, then add the diced bacon. Cook for 10–15 mins until crispy with a slight chew. Drain and remove from the pan.
Remove the grease from the pan, but leave the drippings and bits of bacon in there. Then add the diced white onion and saute for 3 minutes. Then add the coffee, brown sugar, and raspberries and stir to combine. Once the berries start to break down, add the salt and pepper, then put the bacon back in the pan.
Simmer on medium-low for 45–50 mins, or until the bacon jam has thickened up. Remove and set aside while making the burgers.
Heat a skillet or griddle over medium-high heat, then place down the 75/25 ground beef. Before smashing, place some of the thinly sliced jalapeños on top and then season with the jalapeno salt.
Carefully flip the burgers after about 90 seconds, and then top them off with Havarti cheese. Let them cook for 30 more seconds while the cheese melts, then remove.
To build the burger, grab a pretzel bun and add whipped cream cheese to the bottom. Then place down two of the jalapeno patties before covering the top bun in the bacon jam! Place the top bun down, and enjoy!
