Preheat the oven to 350 degrees F.
Open both cans of croissants and roll them out on a floured surface. Make sure the perforations are no longer there.
Spread a small amount of the melted butter on one layer of croissant dough. Sprinkle with ¼ cup of chocolate chips.
Top with the second layer of croissant dough.
Slice the dough into long strips. Roll each strip up, similar to a cinnamon roll.
Brush the top of each roll with remaining melted butter.
Place each roll in a prepared muffin tin.
Bake for approximately 20 minutes, or until they are golden brown.
While they are baking, melt ¼ cup chocolate chips in the microwave.
Remove the cruffins from the oven and let cool slightly. Drizzle with melted chocolate.
