Description

1. Step 1Preheat oven to 350° and grease 2 standard 12-cup muffin tins with butter. In the large bowl of a stand mixer fitted with the paddle attachment, cream butter, brown sugar, and granulated sugar until smooth, airy, and slightly paler in color, about 4 minutes. Add eggs and vanilla and continue to beat until light and fluffy, about 3 minutes more.
2. Step 2In a medium bowl, whisk flour, espresso powder, baking powder, and salt. Gradually add dry ingredients to butter mixture and beat until just combined, then fold in espresso and chocolate chips.
3. Step 3Place 2 tablespoons dough in each prepared muffin cup. Using your finger, create a well in the center of dough. Bake cookies until slightly browned, about 15 minutes.
4. Step 4While cookies are still warm, grease a shot glass or round spice jar with butter. Press into the center of each cookie to create a deeper well. Let cool 15 minutes in pan, then transfer to a wire rack and let cool completely.
