Editorial Guidelines Updated on October 18, 2019 Print Rate It Share Share Tweet Pin Email Prep Time: 30 mins Total Time: 2 hrs Yield: 20 to 25 sandwich cookies We've taken the guesswork out of making this classic French cookie, so you can prepare the dessert at home (for less than 25 cents a pop!). Be sure to weigh the ingredients precisely, and follow the step-by-step directions to make meringue, fold in the almond mixture, and pipe the batter into rounds. Delight one and all with the gorgeous, delicious, professional-looking results. Ingredients ⅔ cup sliced blanched almonds (71 grams) ⅔ cup confectioners' sugar 2 large egg whites, room temperature ¼ cup granulated sugar (53 grams) ½ teaspoon instant-espresso powder, plus more for sifting ¼ cup unsweetened cocoa powder Filling ¼ teaspoon instant-espresso powder 2/3 cup Swiss meringue buttercream Directions Preheat oven to 350 degrees with rack in lower third. Place almonds in a food processor; process until as fine as possible, about 1 minute. Add confectioners' sugar; process until combined, about 1 minute. Pass almond mixture through a fine-mesh sieve. Transfer solids in sieve to food processor; grind and sift again, pressing down on clumps. Repeat until less than 2 tablespoons of solids remains in sieve. Whisk egg whites and granulated sugar by hand to combine. Beat on medium speed (4 on a KitchenAid) 2 minutes. Increase speed to medium-high (6) and beat 2 minutes. Then beat on high (8) 2 minutes more. The beaten egg whites will hold stiff, glossy peaks when you lift the whisk out of the bowl. Add instant-espresso powder, and beat on highest speed 30 seconds. Add dry ingredients all at once. Fold with a spatula from bottom of bowl upward, then press flat side of spatula firmly through middle of mixture. Repeat just until batter flows like lava, 35 to 40 complete strokes. Rest a pastry bag fitted with a 3/8-inch round tip (Ateco #804) inside a glass. Transfer batter to bag; secure top. Dab some batter remaining in bowl onto corners of 2 heavy baking sheets; line with parchment. With piping tip 1/2 inch above sheet, pipe batter into a 3/4-inch round, then swirl tip off to one side. Repeat, spacing rounds 1 inch apart. Tap sheets firmly against counter 2 or 3 times to release air bubbles. Sift espresso powder over half of unbaked rounds. Filling: Dissolve instant-espresso powder in 1/4 teaspoon hot water; mix into Swiss meringue buttercream. Bake 1 sheet at a time, rotating halfway through, until risen and just set, 13 minutes. Let cool. Pipe or spread filling on flat sides of half of cookies; top with remaining half. Wrap in plastic and refrigerate. Cook's Notes Best eaten after 3 to 5 days of refrigeration. Rate it Print
