Mini Mermaid Shortbread Bites

I think I repeat myself in every mermaid dessert recipe, but anything mermaid brings me back to childhood. The magical days when I believed that I could transform into a siren of the sea one day.

These days, I think I’ve watched too many years of Shark Week. I respect, appreciate, but also FEAR the mysterious creatures of the ocean. I think I’ll stick to the kitchen and watch them from the screen!

I absolutely love how these mermaid shortbread cookies turned out. The slightly irregular look gives them a natural, organic vibe that belongs in the ocean. I think they are pretty for any type of under the sea themed event.

Mermaid Shortbread Bites Ingredients

Here’s what you need to make this mermaid cookie recipe. The measurements are in the recipe card below.

  • All-purpose flour
  • Granulated sugar
  • Butter (cold and cut into chunks)
  • Water
  • Royal blue, violet, rose, and teal color gels
  • Mermaid sprinkles
  • Gold edible spray glitter

Mini Mermaid Cookies Directions

Preheat the oven to 325°F (163°C) and line a baking sheet with parchment paper. Set it aside.

In a bowl, combine the flour and sugar, mixing well. Add the cold butter chunks to the bowl and use a pastry blender to cut the butter into the flour and sugar until the mixture gets crumbly.

Add water to the mixture, and use a spoon to bring the dough together. Once it starts to come together, remove the dough from the bowl and knead it a few times with your hands until it becomes smooth.

Coloring dough in bowls.

Divide the dough into thirds. To create the mermaid colors you want, use the color gels to dye one portion royal blue, another portion teal, and the remaining portion a mix of violet and rose to get a beautiful shade of purple.

Place the differently colored dough portions next to each other and gently flatten them with your hand, allowing them to stick together. Transfer the flattened dough onto the parchment paper-lined baking sheet. Use a rolling pin to roll the dough into a thickness of about 1/4 inch (0.6 cm).

Sprinkle the mermaid sprinkles over the rolled-out dough and gently press them into the surface. This adds a touch of magic and texture to the cookies.

Using a pizza cutter or a pastry cutter, cut the dough into 1/2-inch (1.3 cm) squares. Then, cut each square into a triangle shape. Spread the cookies apart on the baking sheet by lifting and separating them, making sure they have enough space to expand during baking.

Bake the cookies in the preheated oven for 12-14 minutes, or until the bottoms begin to turn a delicate golden brown. Once baked, remove them from the oven and allow them to cool completely before serving.

Recipe Swaps and Variations

  • Sprinkles: Feel free to use any type of sprinkles you want. You can also skip them and just use edible glitter or luster dust.
  • Chocolate drizzle: You can dip the shortbread cookies into chocolate or create a chocolate drizzle. Just melt chocolate or white chocolate chips to do so.
  • Shapes: You can use cookie cutters to create shapes instead of cutting them into triangles. Use a mermaid tail, seashell, or fish-shaped cookie cutters to get fun shaped cookies.
  • Colors: Of course, the colors are entirely up to you, as well. Create whichever shades you choose using the color gels.

Recipe Notes and FAQ

Can I make these shortbread bites ahead of time?

Absolutely! These Mermaid Shortbread Bites can be made in advance. Once cooled completely, store them in an airtight container at room temperature. They should remain fresh for up to a week.

Can I freeze the dough or baked cookies?

Yes, you can freeze both the dough and the baked cookies. If freezing the dough, wrap it tightly in plastic wrap or place it in a freezer-safe bag. Thaw the dough in the refrigerator before making the cookies. For freezing baked cookies, make sure they have cooled completely, then store them in a freezer-safe container or bag. Thaw the cookies at room temperature before serving.

How can I get a more uniform look?

The irregular and organic appearance of these cookies pictured adds to their charm and reminds me of the natural beauty of the ocean. If you prefer a more uniform shape, flour your dough and try rolling the dough on a surface other than parchment paper.
