Notes
Use salted butter that is softened to room temperature.
Once you add the flour, do not over mix. Stir just until combined.
Keep the chunks of cookies in fairly large pieces. These can easily be broken apart with your hands. If the pieces are too fine, the cupcakes will become a grayish color.
When adding cookies, use a spatula and fold cookies into batter.
Check your cupcakes at 15 minutes. If they aren't done check again in one more minute.
Allow cupcakes to cool in tins for 5 minutes. Then remove and finish cooling on a baking rack.
