Preheat the oven to 350 degrees F.
Line a cupcake pan with cupcake liners.
Prepare cake mix (or your own recipe) according to the directions.
Add ½ cup of mini chocolate chips. Stir until combined.
Fill each cupcake liner ½ full of batter.
Bake for 12-15 minutes, or until you can insert a toothpick and it will come out clean.
Remove from the oven, and set on a cooling rack to cool completely, before frosting.
Once cupcakes are cool, snip off the end of a pastry bag or ziplock bag and insert the frosting tip.
Place the bag into a large cup, and fold the top of the bag over the rim of the cup. Fill with frosting.
Push frosting towards the bottom of the bag, and remove as mush air as you can.
To frost with this tip, put your frosting bag over the middle of the cupcake, and guide using one hand, squeeze the frosting bag with the other hand; start in the middle of the cupcake, swirl to the outer edge, around the cupcake, and back into the middle.
Top frosted cupcakes with mini chocolate chips.
