01 - In a medium bowl, combine cream cheese, cheddar cheese, crumbled bacon, diced jalapeños, garlic powder, onion powder, black pepper, and sliced green onions. Mix until thoroughly combined and creamy.
02 - Lay an eggroll wrapper on a clean surface with one corner pointing toward you. Place approximately 2 tablespoons of filling in the center-bottom section of the wrapper.
03 - Fold the bottom corner over the filling, then fold in both side corners. Roll tightly toward the top corner, brushing the final flap with beaten egg to seal completely. Repeat with remaining wrappers and filling.
04 - Pour vegetable oil to a depth of 2 inches in a deep skillet or pot. Heat to 350°F, monitoring temperature with a thermometer for accuracy.
05 - Fry eggrolls in batches without overcrowding the pan. Turn occasionally for even cooking until golden brown and crispy, approximately 3-4 minutes per batch.
06 - Remove eggrolls with a slotted spoon and transfer to paper towels to drain excess oil. Let cool for 2-3 minutes before serving.
