01 - Preheat oven to 375°F. Line a large rimmed baking sheet with parchment paper.
02 - In a medium mixing bowl, combine cream cheese, cheddar cheese, minced garlic, smoked paprika, onion powder, salt, and pepper. Mix with a fork until completely smooth and well incorporated.
03 - Spoon approximately 1 tablespoon of cheese mixture into each jalapeño half. Use the back of the spoon to smooth the filling evenly, mounding slightly.
04 - Unroll crescent dough onto a clean surface. Using a sharp knife or pizza cutter, slice dough crosswise into thin strips about 1/4 inch wide.
05 - Wrap each stuffed jalapeño with dough strips in a crisscross pattern to resemble bandages. Leave a small exposed gap near the tapered end for placing eyes later.
06 - Arrange wrapped poppers on the prepared baking sheet, leaving 1 inch between pieces. Brush dough lightly with beaten egg for golden browning.
07 - Bake for 16 to 18 minutes until dough is deep golden brown and fully cooked, and cheese filling is bubbling.
08 - Let cool on baking sheet for 5 minutes. Press two candy eyes or olive slices into the exposed area on each popper to complete the mummy face.
09 - Transfer to a serving platter and serve immediately while still warm. Accompany with ranch dressing, sour cream, or salsa if desired.
