Preheat oven to 375 degrees Fahrenheit and butter a baking dish.

Place the bread cubes on a baking sheet and bake the bread until lightly browned/crisp (approximately 8 to 10 minutes).

Melt butter in a pan over medium heat, then add the jalapeño peppers, yellow onions, celery, salt, and pepper. Sauté the vegetables until the onions are translucent (approximately 10 minutes).

Add the lager beer to the vegetables and stir frequently until the beer evaporates, approximately 5 minutes.

In a large mixing bowl, combine the vegetables, bread, chicken broth, cheddar cheese, eggs, and green onions. Stir to combine, then transfer the mix into the buttered baking dish.

Cover the baking dish with aluminum foil, then bake the stuffing for 20 minutes covered. Remove the cover and bake for an additional 20 minutes, or until the top of the stuffing is lightly browned.

Remove from oven and let the stuffing sit for 5 minutes to cool. Serve.
