Delightful Neapolitan Desserts

In a large bowl, combine butter and sugar. Beat at medium speed with an electric mixer until creamy. Add eggs, one at a time, beating well after each addition. Beat in vanilla.

In a medium bowl, combine flour, baking powder, and salt. Gradually add flour mixture to butter mixture, beating until combined. Divide dough into thirds.

In a medium bowl, combine melted chocolate and one-third of dough. Beat at medium speed until well combined.

In a separate medium bowl, combine one-third of dough, strawberry extract, and desired amount of red food coloring. Beat at medium speed until well combined. Divide each color of dough into 4 pieces. Wrap each piece of dough in plastic wrap. Refrigerate for 1 to 2 hours, or until chilled.

Roll each piece of dough into a 12-inch rope to form 12 ropes. Using 2 ropes of each color, form 2 logs, alternating colors; press ropes together gently to adhere. Wrap logs in parchment paper, and freeze for 2 hours.

Preheat oven to 350°. Line baking sheets with parchment paper.

Slice each log into 1/2-inch-thick slices. Place on prepared pans. Sprinkle with white sparkling sugar. Bake for 10 to 12 minutes. Cool on pans for 2 minutes. Transfer to wire racks to cool completely.
