FINE SUGAR RECIPES

Steps:

• Heat oven to 350 degrees. Lightly butter a 9-by-13-inch baking pan. Line the pan with parchment paper, running it up the two long sides of the pan and letting it extend past the rim by about 2 inches.
• Make the bars: In a medium bowl, whisk together the flour and salt. In a large bowl with an electric mixer, or in the bowl of a stand mixer fitted with the paddle attachment, beat butter and cream cheese on medium speed until well blended, about 1 minute. Add the granulated sugar and beat until smooth, about 1 minute. Add the egg and vanilla and beat on low speed until well combined, about 1 minute. Turn off the mixer and scrape down the bowl with a rubber spatula. Gradually add the flour mixture, mixing on low speed just until blended, about 1 minute.
• Using a spatula, scrape the dough into the prepared baking pan and spread it into an even layer. Bake just until the edges are starting to turn light golden brown, and a toothpick inserted in the middle has moist crumbs, 20 to 25 minutes. (Do not overbake! The bars should be quite moist, and almost slightly underbaked in the middle.) Remove the pan from the oven and set it on a wire rack. Let cool completely. When fully cooled, remove the bars from the pan using the overhanging parchment paper.
• Make the frosting: Place the butter in the bowl of a stand mixer fitted with the paddle attachment. Beat the butter on medium speed until creamy, about 1 minute. Add 1 cup confectioners’ sugar, beating on low speed until fully combined, then repeat with remaining 1 cup confectioners’ sugar. Add the 1 tablespoon milk or heavy cream, 1 teaspoon lemon juice, the vanilla, salt and food coloring, if using, and beat on medium speed until the frosting is light and fluffy, scraping down the sides halfway through, about 4 minutes. Add more milk if needed to thin out the mixture. Add lemon juice and vanilla to taste.
• Using a spatula, spread the frosting on top, then decorate with sprinkles, if using. Cut into 20 bars and serve.

Steps:

• For the cookies: Whisk together the flour, baking powder and salt in a small bowl.
• Beat the superfine sugar and butter with an electric mixer on medium speed in a large bowl until light and fluffy, about 5 minutes; beat in the egg, then the vanilla. Add the flour mixture and mix on medium-low speed until completely incorporated. Divide the dough in half, pat into 2 discs about 1/4 inch thick, wrap in plastic wrap and refrigerate until firm, about 1 hour.
• Position oven racks in the top and bottom thirds of the oven and preheat to 350 degrees F. Line 2 baking sheets with parchment paper.
• Let the dough sit at room temperature for a few minutes to make rolling easier. Roll out 1 disc of dough at a time between 2 pieces of parchment paper until 1/8 inch thick. Cut out shapes with cookie cutters and arrange about 2 inches apart on the prepared baking sheets.
• Bake until the cookies are golden brown on the bottom, 10 to 12 minutes. Let the cookies cool on the baking sheets until firm enough to transfer to a wire rack; let cool completely.
• Gently gather any scraps of dough into a ball and press into a disc; wrap in plastic wrap and refrigerate the disc until firm enough to roll, about 1 hour. Cut out as many cookies as possible and bake.
• For the royal icing: Beat the confectioners' sugar, meringue powder and 1/3 cup water with an electric mixer on medium-high speed in a large bowl until stiff peaks form. Beat in the food coloring if using. (The icing can be stored in an airtight container at room temperature for up to 2 days.)
• Decorate the cookies with the icing; top with decorating sugar and sprinkles if using.
