Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
In a large bowl, combine the ground beef, chopped jalapeños, half the cheddar cheese, egg, chili powder, salt, and black pepper. Mix until evenly blended.
Divide the meat mixture into four equal portions. Flatten each portion into a patty, place about 1/4 cup of prepared Stove Top Stuffing in the center, then fold the edges over to enclose the stuffing and shape into a mini meatloaf.
Place the meatloafs on the prepared baking sheet. Bake for 25 minutes.
Remove the baking sheet from the oven and sprinkle the remaining cheddar cheese over the top of each meatloaf. Return to the oven for 5 more minutes until the cheese melts.
