Creating these Mummy Jalapeño Poppers is straightforward and fun. Just follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Jalapeños: Slice jalapeños in half lengthwise and remove seeds for a milder version, or leave them for extra heat.
3. Mix Filling: In a bowl, combine softened cream cheese, shredded cheddar cheese, garlic powder, and onion powder. Mix until well combined.
4. Stuff the Jalapeños: Spoon the cheese mixture into each jalapeño half, filling generously.
5. Unroll Dough: Roll out the crescent roll dough and separate it into triangles.
6. Cut the Strips: Using a pizza cutter or knife, cut each triangle into thin strips.
7. Wrap the Mummies: Wrap the strips around the stuffed jalapeños in a mummy-like fashion, leaving gaps for the “eyes.”
8. Egg Wash: Beat the egg and brush it over the wrapped dough for a golden finish.
9. Add Eyes: Place two slices of black olives on each jalapeño to create eyes.
10. Bake: Arrange the poppers on a baking sheet and bake for 15-20 minutes or until golden brown and crispy.
