Add oil to the fill line on your deep fryer, or add 2" to a deep cast-iron skillet. Preheat to 350F.
Prepare two bowls. Add the eggs to one and beat them. Add the crushed cinnamon toast crunch to the other.
Dredge each shrimp in the eggs, then place in the cinnamon toast crunch. Toss some over the top of the shrimp then gently press down so that it adheres.
Once you have battered all the shrimp, gently add them to your preheated oil. Fry 3 minutes on each side.
Remove from the batter and set on a cooling rack over a baking sheet to drain any excess oil.
