The cookies from Barbie Princess charm school

Directions

1. Make the Dough:
   Combine the flour, sugar, and butter in a bowl. Mix until the butter is evenly distributed, creating a flaky texture.
   Add the egg yolk and ice-cold water, 1 tbsp at a time, until a dough begins to form.
   Divide the dough into two equal portions. Wrap one portion in plastic wrap and refrigerate for 1-2 hours.
   In the second portion, knead in the cocoa powder until fully incorporated. Wrap this portion in plastic wrap and refrigerate for 1-2 hours.
2. Prepare the Dough for Baking:
   After chilling, take 1/4 of the chocolate dough and knead it into the plain dough for a marbled effect.
   Roll out both doughs (keep them thin for better results) and cut out your desired cookie shapes.
   Place the shapes on parchment-lined baking sheets.
   Bake at 165°C (330°F) for 10-12 minutes. Let the cookies cool completely on a wire rack.
3. Prepare the Chocolate Frosting:
   Place the chopped chocolate in a bowl. Pour the boiling cream over it and stir until smooth.
   Refrigerate for 30 minutes, then whip the mixture with an electric mixer until fluffy.
4. Prepare the Pink Frosting:
   Place the white chocolate in a bowl. Pour the boiling cream over it and stir until smooth.
   Add a small amount of pink gel food coloring and mix well.
   Refrigerate for 30 minutes, then whip with an electric mixer until fluffy.
5. Optional Glaze for Shine:
   In a small saucepan, combine sugar and water. Bring to a boil and simmer until the mixture thickens slightly.
   Brush the glaze over the cookies before frosting.
6. Assemble the Cookies:
   Frost each cookie with the chocolate frosting, pink frosting, or a combination of both.
   Place a second cookie on top if making sandwich cookies, or leave them as single frosted cookies.
7. Serve and Enjoy:
