In a medium sized bowl, whisk to combine the flour and Cajun Seasoning. Set aside.

Place beaten eggs in a separate shallow bowl and the panko bread crumbs in a third shallow bowl.

Dredge one shrimp through the seasoned flour on all sides. Then place floured shrimp in egg and then coat the shrimp in the bread crumbs. Repeat until all shrimp are breaded.

In a medium size heavy pot, heat oil over medium-high heat, until it reaches 375°F. (You can also check if your oil is ready by dropping in a few breadcrumbs. If they sizzle, your oil is ready.)

Fry shrimp in batches, making sure not to crowd the shrimp, for about 2 minutes, until golden brown. Remove shrimp from oil and transfer to a paper towel lined plate or tray to drain. Repeat with remaining shrimp.

Toss shrimp immediately in bang bang sauce and serve topped with green onions!
