Heat 3 inches of oil in a deep pot for frying.

In a bowl, mix pancake mix, egg, milk, and 2 teaspoons of vegetable oil until most lumps are gone. Let the batter rest for 5 minutes.

Assemble the s'mores by breaking graham crackers in half. Place a marshmallow on one graham cracker half, top with half a chocolate bar, and another graham cracker square. Repeat for all s'mores.

Dip each s'more in the batter using tongs, shaking gently to remove excess batter.

Using tongs, carefully place the battered s'mores into the hot oil. Hold them until the batter starts to cook to prevent falling apart. Fry for 3-4 minutes until golden brown.

Remove the fried s'mores with a slotted spoon and place them on a plate lined with a paper towel to absorb excess oil. Repeat for all s'mores.

Let the s'mores cool for 5-10 minutes before serving. Enjoy!
