8ouncessemi-sweet chocolate, cut into ½-inch chunks(or Nestle's Chocolate Chunks) ~ you can add a few extra chunks to sprinkle on top of each cookie cupcake, if you'd like
Instructions
Preheat oven to 375°F. Line two standard 12-cup muffin tins with paper liners.
In a medium bowl, whisk together the flour, baking powder, and salt; set aside.
Put the butter and sugars into the bowl of an electric mixer fitted with the paddle attachment (or just use a regular hand mixer), and mix on medium-high speed until pale and fluffy. Mix in the eggs, 1 at a time; add vanilla. Reduce speed to low. Add the flour mixture in 2 batches, alternating with the milk. Stir in the chocolate chunks with a rubber spatula.
Spoon ¼ cup batter into each paper liner. Bake until pale golden and a toothpick inserted in the center comes out clean, about 20 minutes. Transfer the cupcakes to wire racks; let cool completely.
Cupcakes can be stored in airtight containers at room temperature up to 3 days. They'll also store well in the freezer, just seal them in a container and de-frost as you're ready to eat them.
