Wow. Really. Wow. These are amazingly rich and decadent. I needed a big glass of milk after eating one. And one was plenty to fill my chocolate craving! If you make these, which you should, make them when you are planning to give a bunch away or you have company. Otherwise they will tempt you until you eat the whole batch!
1 1/4 cups butter, room temperature*
2 cups powdered sugar
1/3 cup dutch processed cocoa powder
1/4 teaspoon salt
1/4 cup sour cream
1 teaspoon vanilla
2 1/4 cup flour
2 cups semisweet chocolate chips
about 1/3 cup cocoa (or rolling)
about 2/3 cup powdered sugar (for rolling)
Preheat oven to 325 degrees. Line 2 baking sheets with parchment paper.
Cream butter and slowly add in powdered sugar until well combined. Sift cocoa and salt together and add to cream mixture. Add in vanilla and sour cream. Slowly add in flour and mix until no streaks are left. Stir in chocolate chips. If dough is soft, chill for 30 min.
Roll dough into 1 inch balls and then roll in cocoa powder. Place on baking sheets. You can put them pretty close together as they won't spread much. Bake for 10 min. They will be just barely set but don't cook too long or they will be dry. Remove from oven and let cool on sheet for 3-5 min. Remove to wire rack to cool for 30-45 min. Then roll in powdered sugar and store in airtight container.

My notes:
*Melanie from Kitchen Cafe had a great note about butter. She says that butter is perfect for creaming when you can press your finger on the butter and it gives just a little but isn't easy to go all the way through. That is important for this recipe because you don't want the dough to be to sof to handle. Chilling the dough is a good option if your kitchen is warm or your butter got too soft. I used just 1 bag of chips, which isn't quite 2 cups and I also used regular cocoa powder and they were still great!
