A morning treat gains all-day appeal with these cakey chocolate cookies. Like breakfast waffles, the cookies are prepared on a waffle iron. For best results, make sure the surface is nice and hot before you pour the batter.

　　

Ingredients

makes about 4 dozen

　　3 ounces unsweetened chocolate, coarsely chopped

　　18 tablespoons (2 1/4 sticks) unsalted butter

　　4 large eggs

　　1 teaspoon pure vanilla extract

　　1 1/2 cups granulated sugar

　　1/2 teaspoon coarse salt

　　1 1/2 teaspoons ground cinnamon

　　1/2 cup plus 2 tablespoons unsweetened Dutch-process cocoa powder

　　1 1/2 cups all-purpose flour

　　1/4 cup confectioners’ sugar, plus more for dusting

　　1 1/2 tablespoons whole milk

　　Vegetable oil cooking spray

　　

Step 1

Melt chocolate with 1 cup butter (2 sticks) in a saucepan over medium-high heat, stirring constantly. Let cool slightly.

　　

Step 2

Put eggs, vanilla, and granulated sugar in the bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until pale, 4 to 5 minutes. Mix in chocolate mixture, salt, cinnamon, 1/2 cup cocoa powder, and the flour.

　　

Step 3

Heat a waffle iron until hot. Lightly coat grids with cooking spray. Spoon about 1 tablespoon batter onto center of each waffle-iron square to make 1 1/2-inch rounds. Close cover; cook until set, about 1 1/2 minutes. Transfer to a wire rack, bottom sides up. Let cool completely. Repeat with remaining batter, coating grids with cooking spray after each batch.

　　

Step 4

Melt remaining 2 tablespoons butter in a small saucepan over low heat. Add confectioners’ sugar and remaining 2 tablespoons cocoa powder; stir until smooth. Stir in milk.

　　

Step 5

Gently dip one surface of each cookie in icing so that just the waffle lines (not gaps) are coated. Repeat with remaining cookies and icing. Transfer to wire racks; let stand until set, about 10 minutes. Dust iced surfaces of cookies with confectioners’ sugar. Cookies can be stored in single layers in airtight containers at room temperature up to 2 days.
