Biscuit Sandwich Cookies Recipes

Steps:

• Preheat oven to 325 degrees. Pulse flour, sugar, and salt in a food processor until combined. Add butter, and pulse until the mixture resembles coarse crumbs. With machine running, pour in 1/4 cup cream and the vanilla, and process until dough just comes together.
• Roll dough between lightly floured sheets of parchment until 1/16 inch thick. Using a 2 1/2-inch fluted cutter, cut out 36 rounds, gathering together scraps and rerolling if needed. Space 1 inch apart on parchment-lined baking sheets. Chill in freezer until firm, about 15 minutes.
• Whisk together egg yolk and remaining tablespoon cream. Brush onto tops of cookies. Bake until golden brown, 15 to 20 minutes. Let cool. (Unfilled cookies can be stored in an airtight container up to 4 days.)
• Turn over half the cookies, and spread 1 heaping teaspoon chocolate or chocolate-hazelnut spread onto each. Top with remaining cookies. Refrigerate until set, about 15 minutes (or up to 2 days; cookies will soften slightly with longer storage).

Steps:

• Cookies: Put an oven rack in the center of the oven. Preheat the oven to 325 degrees F. Line 2 baking sheets with parchment paper or silicone mats. Set aside.
• In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Using an electric stand mixer fitted with a paddle attachment, beat the butter and sugars together until fluffy. Beat in the egg and vanilla. With the machine running, gradually add the flour mixture until just blended. Stir in the chocolate chips. Using a 1-ounce ice cream or cookie scoop, form 12 equal-sized pieces of dough onto each baking sheet. With damp hands, form the dough into balls. Flatten the tops of the dough slightly and bake until the tops of the cookies begin to crack slightly, about 14 minutes. Cool for 5 minutes. Transfer the cookies to a wire rack to cool completely, about 20 minutes.
• Filling: In a medium bowl, using an electric mixer, beat the cream cheese and vanilla together until fluffy. Gradually add the powdered sugar and mix until smooth. Color the frosting by mixing in the food coloring, 1 drop of at a time, until the desired color is reached. Add water, if needed, 1/2 teaspoon at a time, to make the consistency spreadable.
• Spread the frosting on the flat side of half of the cookies and put the remaining cookies on top. Refrigerate for 30 minutes to allow the filling to stiffen slightly. Serve at room temperature.

Steps:

• Line a baking sheet with a silicone baking mat.
• Beat egg whites in the bowl of a stand mixer fitted with a whisk attachment until whites are foamy; beat in white sugar and continue beating until egg whites are glossy, fluffy, and hold soft peaks. Sift confectioners' sugar and ground almonds in a separate bowl and quickly fold the almond mixture into the egg whites, about 30 strokes.
• Spoon a small amount of batter into a plastic bag with a small corner cut off and pipe a test disk of batter, about 1 1/2 inches in diameter, onto prepared baking sheet. If the disk of batter holds a peak instead of flattening immediately, gently fold the batter a few more times and retest.
• When batter is mixed enough to flatten immediately into an even disk, spoon into a pastry bag fitted with a plain round tip. Pipe the batter onto the baking sheet in rounds, leaving space between the disks. Let the piped cookies stand out at room temperature until they form a hard skin on top, about 1 hour.
• Preheat oven to 285 degrees F (140 degrees C).
• Bake cookies until set but not browned, about 10 minutes; let cookies cool completely before filling.

Steps:

• To make the cookies, tip the sugars and butter into a large bowl. Get a grown-up to help you use an electric hand mixer to blend them together until the mixture looks smooth and creamy, and a little paler in colour.
• Carefully break in the eggs, one at a time, mixing well between each egg and pausing to scrape down the sides with a spatula. Mix in the vanilla. (To avoid unwanted crunchy bits, get your helper to crack the eggs into a separate bowl first, then it's easy to pick out any shell before tipping into the mixture.)
• Sift in the flour and baking powder, then mix well with a wooden spoon.
• Stir through the chocolate chunks. Use your hands to squeeze the dough together in 1 big lump, then split into 2 even pieces. Put each piece on a sheet of cling film.
• Roll each piece of dough in the cling film so that they form thick sausage shapes, then seal the ends. Put them in the fridge and chill for at least 3 hrs or overnight - can be frozen at this point.
• Heat oven to 180C/160C fan/ gas 4. Take the dough rolls out of the fridge, unwrap and use a small knife to slice each one into 12 pieces, so you have 24 in total.
• Place the slices on a baking tray lined with baking parchment. Ask a grown-up to put this in the oven to bake for 20 mins or until the cookies are golden brown on the edges, but still pale in the centre.
• Allow to cool slightly before lifting them onto a wire rack to cool completely. Sandwich the cookies together with ice cream and dig in!
