Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Slice each jalapeño in half lengthwise, removing seeds and membranes. Arrange on the baking sheet.

In a mixing bowl, combine cream cheese, cheddar cheese, garlic powder, onion powder, green onions, salt, and pepper until smooth.

Spoon the filling into each jalapeño half, pressing slightly to prevent overflow.

Sprinkle with optional toppings like Parmesan cheese or bacon bits.

Bake for 15-18 minutes until tops are golden brown and bubbly.

Allow to cool, then garnish with additional chopped green onions before serving.
