1 cup all-purpose flour
1/4 cup cocoa powder
1/4 teaspoon baking powder
5 ounces semisweet chocolate, finely chopped or chips
3/4 teaspoon instant espresso powder
1/2 teaspoon pure vanilla extract
4 tablespoons (1/2 stick) unsalted butter, room temperature
1/2 teaspoon salt
1/4 cup granulated sugar
1/4 cup packed light-brown sugar
1 large egg
peanut butter filling, recipe follows
Sift together the dry ingredients: flour, cocoa powder, and baking powder.
On medium-low heat, melt the chocolate in a heat-proof bowl over a pot of simmering water. Off from heat add espresso powder and vanilla; mix to incorporate. Let cool.
In a stand mixer fitted with the paddle attachment, beat the butter, salt, and sugars on medium speed until light and fluffy. Add egg and mix until combined. Fold in melted chocolate. Add the dry ingredients a little at a time on low speed, scraping down the sides of the bowl. Mix until combined.
Form dough into two discs and wrap in plastic. Refrigerate for at least 1 hour before rolling.
Preheat oven to 375 degrees F. Line baking sheets with oven-safe parchment paper or Silpats.
On a well-floured work surface, roll out one disc of dough to about 1/8-inch thickness. Keep second disc in refrigerator until ready to roll. Cut out cookies and transfer to lined baking sheet, arranging no more than 1 inch apart. Dust off excess flour. Cut out centers of half the cookies. Reshape scraps of dough into a disc, wrap in plastic, and keep in refrigerator until ready to roll again.
Bake cookies for 8 minutes. Let cool completely. Spread cookie bottoms with about 1 teaspoon of peanut butter filling and cover with top, squeezing together and removing any excess that comes out. Yield: 24 sandwiched cookies.
