Place marshmallows in the freezer for at least 30 minutes to keep them firm during frying.

Line a large rimmed baking sheet with paper towels and a wire rack. Set aside.

Add enough canola oil to a large heavy-duty pot to fill it 3-4 inches deep, or to the fill line of an electric deep fryer. Heat the oil to 375°F. Use a candy thermometer if using a stove to monitor the temperature, ensuring it remains between 365°F and 375°F. Most electric deep fryers will maintain a steady 375°F.

In a small bowl, whisk together the whole milk, large egg, and vanilla extract until fully incorporated. In a large bowl, add the buttermilk pancake mix and form a well in the center. Pour the milk mixture into the well and gently whisk until combined, leaving the batter slightly lumpy for a light texture.

Add 4-5 frozen marshmallows to the bowl of batter. Fully coat each marshmallow on all sides using your fingers.
06 -
Carefully drop the coated marshmallows into the hot oil. Fry for 25-30 seconds per side or until lightly golden brown, approximately 1 minute per batch. If necessary, gently flip the marshmallows using a slotted spoon for even frying.
07 -
Use a large slotted spoon to lift the fried marshmallows out of the oil and place them on the prepared baking sheet to drain off excess oil. Repeat until all marshmallows are fried.

Place the fried marshmallows on a large plate. Lightly dust with powdered sugar. Optionally, top individual servings with whipped cream, a drizzle of chocolate sauce, and rainbow jimmie sprinkles.
