Making Roasted Jalapeno Popper Grilled Cheese is straightforward. Just follow these simple steps for a delicious result:

1. Roast Jalapenos: Preheat your oven to 400°F (200°C). Arrange the jalapenos on a baking sheet and roast for about 15 minutes or until the skins are blistered. Remove and let cool before chopping.
2. Prepare Cheese Mixture: In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, chopped roasted jalapenos, garlic powder, onion powder, salt, and pepper. Mix until well blended.
3. Butter the Bread: Spread softened butter on one side of each slice of bread. Make sure to cover the entire surface for optimal crispness.
4. Assemble Sandwich: Place one slice of bread, buttered side down, in a preheated skillet. Add a generous amount of the cheese mixture on top. Cover with another slice of bread, buttered side up.
5. Cook: Cook over medium heat for about 3-5 minutes until the bottom is golden brown. Carefully flip the sandwich and cook the other side for an additional 3-5 minutes, until both sides are golden and crispy and the cheese is melted.
6. Repeat: If making more sandwiches, repeat the steps with the remaining bread and cheese mixture.
7. Slice and Serve: Once cooked, remove the sandwich from the skillet. Allow it to cool for a minute before slicing it in half.
