Split jalepeno pepper down the side, but keep the stem in tact (wear gloves).
With your thumb or a teaspoon, scrape out the seeds and membrane leaving a pocket in which to stuff. Blend cream cheese, cheddar cheese, green onion, and garlic powder. Stuff each pepper with the cheese mixture and place on a sprayed baking sheet and top with a sprinkle of paprika.
Bake for about 25 minutes or until the peppers are softened and cheese is melted. Let sit a few minutes for the cheese to set up before eating.
