Season shrimp with Cajun seasoning and set aside.
Whisk together the cornstarch, flour, Creole seasoning and Italian seasoning in a bowl; then whisk in the egg and then the club soda until well combined. It's okay to have a few lumps in the batter. If you feel the batter is too thick, add more club soda to get the right consistency.
Add oil to a heavy-bottomed pot and heat up to about 350°F over medium-high heat.
Dip the shrimp into the batter and then add to the oil to fry for about 2-5 minutes, or until browned.
Transfer to a paper-lined plate to soak up any excess oil and repeat until all shrimp are fried.
Next, stir together the buffalo sauce, butter, and honey in a microwave-safe bowl.
Microwave for about 90 seconds or until butter is melted.
Stir in cayenne pepper and more Tony’s seasoning; taste and adjust per your spice preference.
Dump shrimp into a large bowl and pour shrimp over them; toss shrimp with sauce until they're fully coated.
