Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper or a silicone baking mat.
Slice the jalapeño peppers in half lengthwise and scoop out the seeds and ribs.
In a small bowl mix the cream cheese, pepper jack cheese, garlic powder, onion powder, and salt and pepper. You can also use a food processor to mix everything.
Fill the jalapeño pepper halves with the cheese mixture. Don't overfill or the cheese will ooze out while baking.
Unroll the crescent roll dough leaving the triangles together and pinching the perforations together. Cut thin strips (about 1/2 inch wide) of dough and wrap one or two pieces around each pepper half. Leave a space at the top open to insert the googly eyes when they are done.
Make an egg wash by combining the egg and about one tablespoon of water. Mix well. Place the mummies on your baking sheet, and brush a thin layer of egg wash on each one.
Bake for about 15 minutes or until the mummies are golden brown. Remove from the oven and place the candy googly eyes in the melted cheese.
Serve immediately and enjoy!
Sharon's Expert Tips:If you are making Easy Halloween Jalapeño Mummies for young children, you might want to substitute Monterrey Jack cheese for the pepper jack cheese to tone down the kick a bit.You can find the candy googly eyes in the baking ingredient section of most grocery stores; they are also available at Michael's and other hobby stores that carry baking and candy making supplies.I use a serrated grapefruit spoon to scoop out the seeds and ribs from the jalapeños. Be sure to wash your hands thoroughly after handling the peppers and avoid touching your eyes or wear gloves.To make the Jalapeño Mummies ahead, I have found it works best to make and stuff the peppers up to 24 hours ahead of time, then cover and store them in the refrigerator. Before your party wrap them with dough and bake them. Be sure to add the googly eyes right with the mummies come out of the oven while the cheese is still melted so they will stick.
