Preheat your oven to 375°F (190°C).

In a large mixing bowl, mix together the crab meat, cream cheese, shredded cheddar cheese, green onions, garlic powder, and Old Bay seasoning until well-blended.

Unroll the crescent roll dough onto a clean surface and separate the triangles.

Spoon about a tablespoon of the crab filling onto the wide end of each dough triangle. Roll the dough over the filling and pinch the edges to seal.

Arrange the stuffed bombs on a parchment-lined baking sheet and brush the tops with beaten egg wash.

Bake for 15-20 minutes or until they are golden brown and crispy.

Let cool for a few minutes before serving.
