Spoon into prepared muffin cups.
Bake in a 375 degree preheated oven for about 10 minutes. Remove the tray from the oven and sprinkle a few extra pieces of chocolate on top then return to the oven to complete baking.for an additional 20 minutes or until a toothpick inserted into the middle of the muffin comes out clean.

Notes
Do not prepare the cake mix according to the directions on the back of the box. Follow the directions listed above.
Depending on the size of your muffin pan, this recipe should make 12 to 16 muffins.
You don't want a lot of excess flour being added to the batter, so start with one tablespoon to lightly coat the chocolate chunks. If you need more, add another teaspoon or two. The additional flour will help the chocolate chunks not sink to the bottom of the muffins while baking.
