Chocolate Hazelnut Truffle Squares Recipes

Steps:

• In a large bowl, sift together confectioners' sugar and cocoa; set aside. , In a small saucepan, melt candy bars and butter. Add cream and reserved cocoa mixture. Cook and stir over medium-low heat until mixture is thickened and smooth. Pour into an 8-in. square dish. Cover and refrigerate overnight. , Using a melon baller or spoon, shape candy into 1-in. balls; press a hazelnut into each. Reshape balls and roll in ground hazelnuts. Store in an airtight container in the refrigerator.

Steps:

• Crust: Preheat oven to 375 degrees with rack in middle. Butter a 9-inch square cake pan. Line bottom and 2 sides with parchment, leaving a 1-inch overhang. Butter parchment.
• With a mixer on medium speed, beat butter with brown sugar, vanilla, and salt until fluffy, about 2 minutes. Reduce speed to low; beat in flour until combined and a soft dough forms.
• Spread dough in prepared pan, pressing evenly with the bottom of a dry-measure cup. Prick all over with a fork. Bake until golden, about 15 minutes. Let cool completely in pan on a wire rack.
• Truffle: In a small saucepan, bring cream just to a boil over medium heat. Remove from heat; whisk in chocolate until melted and combined. Add liqueur and salt, whisking until blended, then stir in nuts. Let cool slightly.
• Pour chocolate mixture evenly over cooled crust. Refrigerate, uncovered, until cold and set, about 2 hours.
• Remove shortbread from pan using parchment; place on a cutting board. Dust top completely with cocoa powder. Cut into 48 squares, dipping knife in hot water and wiping clean before each slice. Refrigerate in a single layer until ready to serve, up to 1 week.

Steps:

• Preheat the oven to 325 degrees F.
• Chop the hazelnuts and place them on a sheet pan. Roast them in the oven for 10 minutes. (If the hazelnuts have skin on them, roast them for 25 minutes.) Set aside to cool.
• Chop the chocolates finely and place in a bowl.
• Heat the cream in a small saucepan until it boils. Immediately pour the hot cream through a fine-meshed sieve into the bowl with the chocolates. With a wire whisk, slowly stir the cream and chocolates together until the chocolate is completely melted. (If the chocolate doesn't melt completely, place the bowl over a pan of simmering water and stir for a few minutes just until it melts.) Whisk in the hazelnut liqueur, coffee, and vanilla. Cover and chill for 45 minutes to 1 hour until pliable but firm enough to scoop.
• With 2 teaspoons or a 1 1/4-inch ice cream scoop, make dollops of the chocolate mixture and place on a baking sheet lined with parchment paper. Refrigerate for about 15 minutes, until firm enough to roll into rough spheres. Roll the chocolate in the chopped hazelnuts and chill again. Truffles are best when they're allowed to set overnight in the refrigerator.

Steps:

• Baking pan or roasting pan at least 2 inches deep and large enough to hold the cake pan with at least 2 inches to spare on each side.
• Position the rack in the lower third of the oven and preheat to 350 degrees. Line the bottom and sides of the pan with foil. Put a kettle of water on to boil for the bain marie when baking in the oven.
• Place chocolate in a large mixing bowl. Combine the 2 egg yolks with vanilla in a small bowl. Place the 3 egg whites in a medium bowl with cream of tartar. Set all 3 bowls aside.
• Combine the cocoa, flour and 2/3 cup sugar in a 1 1/2 quart heavy bottomed saucepan. Whisk in enough of the milk to form a smooth paste. Mix in the remaining milk. Cook over medium heat, stirring constantly with a wooden spoon, to prevent burning (especially around the bottom edges of the pot), until mixture begins to simmer. Simmer very gently, stirring constantly, for about 1 1/2 minutes, or until the mixture visibly thickens. Pour the hot mixture immediately over the chopped chocolate. Stir until chocolate is completely melted and smooth. Whisk in egg yolk mixture. Set aside.
• Beat the egg whites and cream of tartar at medium speed until soft peaks form. Gradually sprinkle in the remaining 1/4 cup of sugar, beating at high speed until stiff but not dry. Fold a quarter of the egg whites into the chocolate mixture to lighten it. Fold in remaining egg whites. Scrape mixture into the cake pan and spread evenly. Set cake pan in baking pan and place on oven rack. Pour enough boiling water into the baking pan to come a third to halfway up the sides of the cake pan.
• Bake for exactly 20 minutes. The cake will only be about 3/4 inches tall. The surface will spring back when gently pressed but cake will still be quite gooey inside. Remove cake pan and water pan from oven. Remove the cake pan from the water and cool completely on a rack. Cover with plastic wrap and refrigerate overnight before serving. Refrigerate up to 2 days or freeze up to 2 months.
• After the truffle sheet is well chilled, lift the edges of the foil to remove the truffle sheet from the pan. Cut the sheet into 7 strips, each about 1 1/4 inches wide, using a long thin sharp knife dipping in hot water and wiped dry between each cut (the cake is very sticky) or cut with dental floss. Cut each strip into 7 squares. Transfer each square to a fluted paper candy cup and or arrange on a serving platter. If garnishing with raspberries, simmer the preserves for a minute or until thick and sticky. Touch the hot preserves with the bottom of each berry before placing it on the truffle square. Refrigerate until serving.

Steps:

• Position racks in the upper and lower thirds of the oven and preheat to 350 degrees F. Spread the hazelnuts on a baking sheet and bake on the upper rack until golden, about 7 minutes. Line 2 baking sheets with parchment paper.
• Whisk the flour, baking powder and salt in a medium bowl. Combine the chopped chocolate and butter in a microwave-safe bowl and microwave in 30-second intervals, stirring, until melted. Add the vanilla and whisk until smooth; set aside.
• Beat the eggs in a large bowl with a mixer on medium speed until foamy, about 1 minute. Gradually add the sugar and beat until thick and pale yellow, about 6 minutes. Gradually add the melted chocolate mixture and beat until combined. Reduce the mixer speed to low; add the flour mixture and beat until just combined, about 1 minute. Fold in the hazelnuts and chocolate chips.
• Drop heaping tablespoons of batter 2 inches apart on the prepared baking sheets. Bake, switching the pans halfway through, until the cookies are slightly puffed and crackly, 12 to 15 minutes. Let cool 5 minutes on the baking sheets, then transfer to a rack to cool completely.

Steps:

• Make hazelnut base:
• Preheat oven to 350°F. Butter bottom and sides of an 8-inch square metal baking pan, then dust with cocoa powder, knocking out excess.
• Finely grind nuts in a food processor with flour, sugar, and salt.
• Melt butter in a 2-quart saucepan, then remove from heat. Add chocolate and whisk until smooth. Add eggs 1 at a time, whisking until smooth. Stir in nut flour until just combined.
• Spread batter evenly in baking pan and bake in middle of oven until top is firm and dry and a tester inserted into center comes out with crumbs adhering, 15 to 20 minutes. Cool completely in pan on a rack, at least 2 hours.
• Make ganache:
• Lightly beat yolks in a bowl. Bring cream with salt just to a boil in a small heavy saucepan, then add half of it to yolks in a slow stream, whisking constantly. Whisk yolk mixture into remaining cream and cook over low heat, whisking, until slightly thickened and an instant-read thermometer registers 170°F (do not let boil).
• Remove from heat and add chocolate, whisking until smooth. Pour ganache over hazelnut base in pan, smoothing top with offset spatula, and chill, covered, until firm, at least 5 hours.
• Cut into squares with a warmed thin knife, wiping off knife after each cut, and remove from pan while still cold.
• Serve truffles cold or at room temperature.

Steps:

• In a small saucepan, bring the cream to the boil. Remove from the heat and pour over the chopped chocolate. Gently stir the mixture until smooth, then add the alcohol or vanilla extract and hazelnuts. Cover and put in the fridge for 30 mins or until the mixture is thick but not solid.
• Scoop out teaspoons of the mixture and roll into small balls with your hands. Put each of your sprinkles or glitters onto separate small plates or bowls. Roll each truffle into the sprinkles or glitter to coat, then chill again to firm up. Will keep chilled for 1 week, or freeze for up to 1 month without the decoration.
