Wash your jalapeños thoroughly. Using a sharp knife, slice each jalapeño in half lengthwise. Use a spoon to remove the seeds and membranes. Wear gloves if you're sensitive to pepper oils—jalapeños can irritate skin and eyes. Arrange the cleaned pepper halves on a baking sheet lined with parchment paper.

In a mixing bowl, add softened cream cheese, shredded cheddar, mozzarella, garlic powder, onion powder, smoked paprika, salt, and pepper. Mix well until the mixture becomes smooth, uniform, and fluffy. Taste and adjust seasonings if needed.

Using a spoon or spatula, stuff each jalapeño half generously with the cheese mixture. Fill them completely but avoid overflowing too much so the cheese does not spill out during baking.

If using bacon, wrap each stuffed jalapeño with one strip of bacon. Secure the bacon with a toothpick if needed. Bacon not only adds flavor but also helps keep the filling inside while baking.

Preheat your oven to 400°F (200°C). Once heated, place the baking sheet in the oven and bake for 18–22 minutes, or until the bacon is crispy and the cheese is melted and golden around the edges.

Let the poppers cool for 5 minutes before serving. The cheese filling will be extremely hot right out of the oven.
