Preheat oven to 400°F. Spray a mini muffin tin with cooking spray. (This recipe makes about 18 mini muffins.)
Trim stems from both jalapeños. Finely dice one jalapeño (remove seeds/membranes if you prefer less heat). Slice the other jalapeño into thin rounds—about one slice per muffin.
Cut the 3 ounces cream cheese into 18 small cubes.
In a medium bowl, stir together the Jiffy corn muffin mix, the diced jalapeño, the large egg, and the 1/3 cup whole milk until just combined.
Divide the batter evenly between the mini muffin cups, filling each cup about 3/4 full.
Push one cream cheese cube into the center of each filled cup so it is mostly covered by batter.
Sprinkle shredded sharp cheddar on top of each muffin, then place one jalapeño slice on each.
Bake for 12 to 15 minutes, until the tops are lightly golden and set.
Let the muffins cool in the tin for a few minutes, run a knife around the edges of each muffin to loosen, then remove from the tin and serve.
