For the Instant Pot: Open the crescent rolls and line each cup in your egg bite mold with the roll dough.
Combine the cinnamon and sugar in a bowl.
Coat the 28 mini marshmallows in the melted butter and then roll in the cinnamon and sugar.
Place 4 covered marshmallows into each cup. Fold the remaining dough over to seal the marshmallow inside of the roll.
Pour 1 cup of water into the bottom of the Instant Pot. Cover the silicone mold with the silicone cover or foil. Place on the trivet in the Instant Pot.
Cook on Manual HIGH for 12 minutes. Quick release the pressure.
Flip the mold upside down onto a plate to remove the rolls. Let the rolls sit and cool for 5 minutes before eating.
For the Oven: Open the crescent rolls and separate each triangle.
Combine the cinnamon and sugar in a bowl.
Use large marshmallows, roll each one in the butter and then in the cinnamon and sugar.
Place the marshmallow into the center of the crescent roll dough and then pull up the sides and completely seal the marshmallow inside of the roll.
Repeat with remaining dough and marshmallows.
Bake at 350° for 10-15 minutes or until golden brown.
