MOCHA MACARONS

Steps:

• 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.

HAZELNUT-MOCHA MACARONS

Steps:

• Line 2 baking sheets with parchment paper.
• Grind 1 cup of the confectioners' sugar, the hazelnuts, and cocoa in a food processor until powdery, about 3 minutes. Sift mixture through a medium mesh strainer onto a piece of parchment paper, then discard any large pieces of nuts that didn't come through the strainer.
• With an electric mixer, beat the egg whites and salt until they hold firm but not dry peaks, about 2 minutes. Gradually add the remaining 1 cup confectioners' sugar, a tablespoon at a time, scraping down the sides of the bowl as needed; this can take up to 3 minutes. Beat for an extra 30 seconds until the peaks are firm and shiny but still not dry. Fold the nut mixture gently into the egg whites with a large rubber spatula. Transfer mixture into a large piping bag fitted with a 1/2-inch plain piping tip. Pipe 32 2-inch by about 1/3-inch thick rounds, evenly spaced, on each of the prepared pans. Set aside to air dry for 30 minutes before baking.
• Meanwhile make the filling: Put chocolate in a medium heatproof bowl. In a small saucepan, bring cream, with espresso powder mixed in, to a boil. Pour cream over chocolate and shake bowl gently so cream settles around the chocolate. Set mixture aside until the chocolate is soft, about 5 minutes. Whisk gently until smooth, taking care not to incorporate too many air bubbles. Cool at room temperature until set up.
• Preheat oven to 325 degrees F.
• Bake macaroons until set and puffed, about 18 to 20 minutes. Take care not to overcook the macaroons or they'll crack. Cool cookies for 5 minutes then gently peel from paper. Let cool completely.
• Spread 1 teaspoon of mocha filling on a cookie and sandwich 2 cookies together.

FLUFFY COFFEE AND WALNUT CAKE WITH MOCHA BUTTERCREAM

Steps:

• Place a rack in middle of oven; preheat to 325°. Lightly butter three 8"-diameter cake pans and line bottoms with parchment paper rounds. Toast 2 cups (250 g) raw walnuts in a single layer on a rimmed baking sheet, tossing halfway through, until golden brown, 12-14 minutes. Let cool. Set aside 1 cup walnuts for serving.
• Meanwhile, cook ¾ cup (1½ sticks) unsalted butter in a small saucepan over medium heat, stirring often, until it foams, then browns, 6-8 minutes. Remove from heat and immediately stir in ½ cup plus 2 Tbsp. vegetable oil or refined coconut oil, melted. Set brown butter mixture aside.
• Pulse remaining 1 cup toasted walnuts in a food processor until coarsely ground (it should be the texture of panko). Transfer to a large bowl and whisk in 2 cups (250 g) all-purpose flour, 2¼ tsp. baking powder, 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and ½ tsp. baking soda.
• Process 4 large eggs, 1¼ cups (250 g) sugar, 2 tsp. vanilla extract, and 1 tsp. instant espresso powder in food processor (no need to clean bowl) until mixture is lightened in color and thickened, about 30 seconds. Stir 2 Tbsp. whole milk into reserved brown butter mixture. With motor running, gradually stream brown butter mixture into egg mixture and process until combined. Add dry ingredients and process just until a smooth batter forms. Divide batter among prepared pans.
• Bake cakes, rotating pans front to back after 15 minutes, until puffed and just starting to pull away from the sides of pans and a tester inserted in the centers comes out clean, 20-22 minutes. Transfer pans to wire racks and let cakes cool 15 minutes. Run a small knife around edges of each cake to release from pan if needed. Turn out cakes onto racks and remove parchment paper; discard. Turn cakes right side up and let cool completely.
• Combine 8 large egg whites, 2¼ cups (450 g) sugar, ¾ tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and ¼ tsp. cream of tartar in the bowl of a stand mixer. Set over a medium saucepan filled with 1½" of simmering water (bowl should not touch water). Heat, stirring and scraping often with a heatproof rubber spatula, until sugar is dissolved and an instant-read thermometer registers 185°, 10-15 minutes.
• Fit bowl onto stand mixer fitted with whisk attachment and beat, starting on low speed and gradually increasing to high, until meringue is shiny and stiff, 8-10 minutes. Beat in 1 tsp. vanilla extract.
• With mixer on medium speed, add 3 cups (6 sticks) unsalted butter, room temperature, cut into pieces, a piece at a time, mixing until incorporated before adding more. Once all the butter has been added, increase speed to high and beat 1 minute. Transfer buttercream in bowl to refrigerator and chill 30 minutes.
• Fit bowl with buttercream back onto stand mixer and add ¼ cup (21 g) unsweetened cocoa powder, sifted if needed, and 2 tsp. instant espresso powder. Beat on medium-low speed, scraping down sides as needed, until combined.
• Using a large serrated knife and long sawing strokes, remove tops of cakes to level if needed. Place a cake layer, right side up, on a cake stand or large plate. Using an offset spatula, spread ¼ cup buttercream over cake, working all the way to the edges. Place second cake layer, right side up, on top; spread another ¼ cup buttercream over cake, working all the way to the edges. Place third cake layer, cut side down, on top, and press lightly to adhere. Spread top and sides of cake with ½ cup buttercream in a thin, even layer. Chill, uncovered, at least 1 hour and up to 12 hours. (If chilling cake longer than 1 hour, cover remaining buttercream in bowl and chill. Bring to room temperature and beat again before using.)

MOCHA-HAZELNUT MACAROON DOMES

Steps:

• For macaroons:
• Preheat oven to 350°F. Line 1 large cookie sheet with parchment. Brush lightly with vegetable oil. Finely grind hazelnuts in processor. Add sugar and flour; blend to powder. With machine running, add egg white and vanilla; blend to paste.
• Spoon mixture into pastry bag fitted with no. 4 (3/8-inch-diameter) round tip. Pipe 3/4- to 1-inch-diameter mound onto parchment about 1/2 inch high and spacing 1 inch apart. Dip finger into water and gently press top of cookie to flatten center slightly. Bake until golden brown, about 12 minutes (cookies will spread to about 1 1/2 inches.) Turn parchment (cookies will adhere) over onto work surface. Brush parchment with just enough water to moisten. Let stand until parchment can easily be pulled off cookies, about 2 minutes. Peel off parchment.
• For ganache:
• Bring cream and butter to simmer in heavy medium saucepan over medium heat. Add instant coffee granules; stir to dissolve. Reduce heat to low. Add chocolate; stir until melted. Mix in vanilla. Pour into bowl. Chill until firm enough to spread, stirring occasionally, about 45 minutes.
• Line cookie sheet with foil. Using icing spatula, spread 1 heaping teaspoon ganache onto flat side of each cookie, mounding to dome in center. Place ganache side up on prepared cookie sheet. Repeat with remaining cookies. Chill until ganache sets, 20 minutes.
• For coating:
• Line cookie sheet with aluminum foil. Melt bittersweet chocolate with vegetable shortening in top of double boiler over simmering water, stirring until smooth. Remove from over water. Grasp 1 cookie between thumb and index finger. Dip ganache portion into melted chocolate. Shake of excess. Turn chocolate side up and place on foil-lined cookie sheet. Top with raspberry or hazelnut. Repeat with remaining cookies. Refrigerate until chocolate sets, about 30 minutes.
• Melt white chocolate in top of double boiler over simmering water, stirring until smooth. Dip spoon into chocolate. Wave from side to side over cookies, forming decorative pattern. Refrigerate until white chocolate sets, about 15 minutes. Place cookies in single layer in airtight containers; chill overnight. (Can be prepared 3 days ahead.) let stand 10 minutes at room temperature before serving.
