Spread the crescent roll dough on a cutting board or clean counter, keeping the dough together in one sheet. Gently press back together any seams that are starting to separate.
1 tube refrigerated crescent rolls
With a large kitchen knife, cut the dough along the short side into 16 even strips. Then, cut each strip in half (following the dotted line) for a total of 32 strips.
Use a pastry brush to spread melted butter on each strip. Roll up the cocktail dogs in the strips of dough, taking care to not roll too loosely, so the dough doesn’t bunch together.
4 Tablespoons salted butter, 14 ounce package of cocktail dogs
Brush melted butter on top of each pig in a blanket. Sprinkle sesame seeds on top of each bundle.
1 Tablespoon sesame seeds
Spray the bottom of the air fryer basket with non-stick cooking spray (or lightly brush with additional butter.
Cook the pigs in blankets in batches, leaving room for the crescent rolls to expand slightly. (Don't crowd the pan). Cook in the Air Fryer at 325°F for 6 minutes, or until the crescent rolls are golden brown.
Let cool for a few minutes, then serve with dipping sauces, like ketchup, mustard, or ranch. Eat within 2 hours of cooking, and refrigerate any leftovers.
