In a small mixing bowl, combine the cream cheese, chopped jalapeños, and garlic powder.

Lay out two slices of bread on a clean surface and top each with one slice of cheese.

Divide the jalapeño filling onto each sandwich and spread out edge-to-edge.

Cut the slices of bacon in half and place onto the sandwiches over top of the jalapeño filling.

Top with remaining slices of cheese and the remaining slices of bread to complete two sandwiches.

Heat a skillet over medium heat.

Spread butter onto the outward-facing sides of the bread on each sandwich. Place the sandwiches onto the skillet and grill until golden brown, then flip and grill the other side until golden brown and the cheese is melted.

Serve hot.
