In a saucepan over medium heat, combine buffalo sauce, brown sugar, rice vinegar, sriracha, minced garlic, and honey. Simmer until thickened into a glaze. Add butter, red pepper flakes, and parsley. Mix well, then set aside in a bowl.
In a shallow bowl, whisk together cornstarch, salt, and black pepper. In another bowl, whisk eggs with salt and black pepper.
Heat vegetable oil to 350°F in a frying pan.
Dip shrimp first in the egg mixture, then in the cornstarch mixture, shaking off any excess.
Fry shrimp in batches until golden, about 6 to 7 minutes. Drain on a wire rack.
Toss the fried shrimp in the prepared glaze.
Garnish with green onions and sesame seeds. Serve over rice, noodles, or veggies!
