  • Butter (room temperature): 14 tablespoons (about 200 grams)
  • Icing Sugar: 2 and 1/2 cups (about 300 grams)
  • Eggs: 3
  • Vanilla Essence: 1 teaspoon
  • Salt: 1 teaspoon (5 milliliters)
  • Plain Flour: 6 and 1/3 cups (about 800 grams)
  • Food Coloring Gels (Red, Yellow, Green, Blue, Purple, Orange): As needed

Marshmallow Filling

  • Egg Whites: 2 large
  • Cream of Tartar: 1/2 teaspoon (2.5 grams)
  • Caster Sugar: 2 tablespoons (27 grams) + 1/3 cup (80 grams)
  • Golden Syrup: 2/3 cup (about 180 grams)


  • Milk Chocolate (melted): 2 and 1/4 cups (about 500 grams)


  1. Make the Dough: Cream together butter and sugar. Add eggs one at a time, mixing well after each addition. Stir in vanilla and salt. Gradually add flour until combined. Divide the dough into six equal parts and color each with a different food coloring gel. Shape into disks.
  2. Layer and Roll: Stack colored disks in two groups (e.g., red, yellow, green and blue, purple, orange). Between sheets of greaseproof paper, roll each stack out to 3mm thick. Use a 9cm cookie cutter to cut 11-12 circles from each stack. Refrigerate on a baking sheet for 30 minutes.
  3. Bake: Preheat oven to 350°F (175°C). Bake cookies for 8 minutes. Allow to cool on trays for 10 minutes before transferring to a wire rack to cool completely.
  4. Make Marshmallow Filling: Whisk egg whites and cream of tartar until soft peaks form. Gradually add 27 grams of sugar and beat until stiff. In a separate pan, heat golden syrup and 80 grams of sugar until dissolved. Combine with egg whites and beat until glossy.
  5. Assemble: Spread marshmallow filling between two cookies and dip in melted chocolate. Allow to set.


  • Color Variety: Use a variety of colors for a more vibrant rainbow effect.
  • Chilling the Dough: Ensure the cookie dough is chilled thoroughly to maintain shape during baking.
  • Chocolate Finish: For a glossier finish, temper the chocolate before dipping the cookies.


Q: Can I use natural food coloring? A: Yes, natural food colorings work, but they may not be as vibrant as synthetic ones.

Q: How long do these cookies keep? A: They can be stored in an airtight container for up to 5 days, but are best enjoyed within 2 days for optimal freshness.
