Preheat your oven to 375°F (190°C). This ensures that the chicken cooks evenly and thoroughly.

Place the chicken breasts between two pieces of plastic wrap or parchment paper. Use a meat mallet or rolling pin to gently pound the chicken to about 1/2 inch thickness. This helps the chicken cook evenly and makes it easier to stuff.

In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, diced jalapenos, garlic powder, onion powder, salt, and black pepper. Mix well until all ingredients are fully incorporated. This creates a creamy, flavorful filling.

Take a portion of the filling (about 1/4 cup) and place it in the center of each chicken breast. Fold the sides over the filling and secure with toothpicks if necessary. This keeps the filling inside during cooking.

In a separate bowl, mix the panko breadcrumbs, grated parmesan cheese, melted butter, and paprika. This mixture will give a crunchy topping to the chicken.

Place the stuffed chicken breasts in a greased baking dish. Evenly sprinkle the breadcrumb mixture over the top of each chicken breast. This adds texture and flavor.

Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the topping is golden brown. You can check the chicken's doneness with a meat thermometer; it should read 165°F (74°C).

Remove from the oven and let the chicken rest for 5 minutes before serving. This allows the juices to redistribute, ensuring moist chicken.

Slice and serve warm, optionally garnished with fresh cilantro or green onions for added freshness.
