For the Dough• 1 ¾ cup all-purpose flour (215g)• ¼ cup natural cocoa powder (25g)• ¼ cup granulated sugar (50g)• 2 teaspoons baking powder• ¼ teaspoon table salt• ½ cup unsalted butter cut into 8 pieces (very cold, I recommend placing your butter in the freezer for 15 minutes before beginning) (113g)• ½ cup heavy cream cold (118ml)• ½ teaspoon vanilla extract• ½ cup semisweet chocolate chips I like to use half mini and half regular-sized chocolate chips (85g)
For the Glaze• ¾ cup powdered sugar (95g)• 2 Tablespoons natural cocoa powder (14g)• 2-3 Tablespoons milk I use whole milk, but any will do• ½ teaspoon vanilla extract
In the basin of a food processor (see notes on web page if you do not have a food processor) combine flour, cocoa powder, sugar, baking powder, and salt and pulse to combine.
Use your hands to quickly work dough together and work the chips into the dough (try to avoid over-handling or overworking the dough as much as possible).
Fold dough in half over itself and gently press the layers together. Rotate dough 90 degrees and fold in half again, repeating until you have done 5-6 folds.
