Ingredients

Cookie Dough Ingredients

  • 1 cup unsalted butter (cold and cubed)
  • 1 cup granulated sugar
  • 1 large egg
  • 1 tablespoon vanilla extract
  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

Frosting Ingredients

  • 1/2 cup unsalted butter (softened)
  • 2 cups powdered sugar
  • 1-2 tablespoons heavy cream or milk
  • 1 teaspoon vanilla extract
  • Pinch salt
  • Gel food colors (teal, aqua, lavender or pink)
  • Mermaid sprinkles
  • Pearls
  • Shimmer dust
  • Tiny shells


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper to prevent cookies from sticking.
  2. Cream Butter and Sugar: In a mixing bowl, cream together 1 cup of cold, cubed unsalted butter and 1 cup of granulated sugar until the mixture is light and fluffy.
  3. Add Egg and Vanilla: Mix in 1 large egg and 1 tablespoon of vanilla extract thoroughly to the creamed butter and sugar mixture.
  4. Incorporate Dry Ingredients: Combine 3 cups of all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add this to the wet mixture and mix until a soft dough forms.
  5. Shape Cookies: Scoop dough into 1/4-cup balls for standard size or 1/3-cup for extra-large cookies. Slightly flatten the tops to ensure even baking.
  6. Bake: Bake the cookies for 9-11 minutes for 1/4-cup cookies or 11-13 minutes for 1/3-cup cookies. Edges should appear set while centers remain soft and pale for perfect texture.
  7. Cool: Allow cookies to cool completely on the baking sheets before frosting to prevent melting.
  8. Prepare Frosting: Beat 1/2 cup of softened unsalted butter until creamy. Add 2 cups powdered sugar, 1 teaspoon vanilla extract, a pinch of salt, and 1 tablespoon heavy cream. Beat until smooth and fluffy; add more cream if necessary for desired consistency.
  9. Color Frosting: Divide the frosting evenly into three bowls. Tint each bowl separately with gel food colors of teal, aqua, and lavender (or pink) to create the mermaid palette.
  10. Create Frosting Log: Lay a sheet of plastic wrap and spoon the three colored frostings side by side in stripes. Roll the plastic wrap into a log and twist ends tightly. Snip one end of the log.
  11. Pipe Frosting: Insert the frosting log into a piping bag fitted with a round tip. Pipe swirls or mounds onto each cooled cookie. Optionally, use an offset spatula to swirl the frosting for an artistic finish.
  12. Decorate: While frosting is still soft, sprinkle the cookies with mermaid-themed sprinkles, pearls, shimmer dust, and tiny shells to enhance the oceanic look.
  13. Chill (Optional): Refrigerate the decorated cookies for 10 minutes to help the frosting set and achieve cleaner edges.

Notes

  • Make sure cookies are completely cool before frosting to avoid melting the buttercream.
  • Use gel food coloring for vibrant colors without thinning the frosting.
  • Press cookie dough balls down gently for consistent baking and texture.
  • For cleaner frosting lines, chill the cookies briefly before serving.
  • Store frosted cookies in an airtight container at room temperature or refrigerated for longer freshness.
