How to Make Mermaid Funfetti Cookies Step by Step

Making these cookies involves preparing the dry ingredients, mixing the butter and sugars, combining everything into a dough, and adding the colorful toppings before baking.

Follow these instructions in order for an easy baking experience.

Step 1: Prepare the Oven and Baking Sheet

Start by preheating your oven to 375°F (190°C).

While the oven heats, take a baking sheet and line it with parchment paper. This prepares the surface for your cookie dough and makes the baking process easier.

Set the prepared baking sheet aside while you work on the dough.

Step 2: Combine the Dry Ingredients

Take a medium-sized mixing bowl and add the all-purpose flour, baking powder, salt, and cornstarch.

Using a whisk, mix these ingredients until they are evenly combined. This step helps distribute the baking powder, salt, and cornstarch throughout the flour.

Once everything is mixed, set the bowl aside.

Step 3: Cream the Butter and Sugars

In a separate mixing bowl, add the softened unsalted butter, packed light brown sugar, and granulated sugar.

Using either a hand mixer or a stand mixer, cream the ingredients together until the mixture becomes smooth.

Make sure your butter has softened to room temperature before starting. This helps it combine properly with both types of sugar.

Step 4: Add the Eggs and Vanilla

Once the butter and sugars are smooth, add the vanilla extract, one large egg, and one additional egg yolk.

Mix everything together until well combined.

Make sure both the egg and egg yolk are at room temperature, as specified in the ingredient list.

Step 5: Mix in the Dry Ingredients

Now it’s time to bring the wet and dry mixtures together.

Gradually add the prepared flour mixture to the butter mixture, adding a little at a time.

Start mixing on low speed until the ingredients begin to combine. Then increase the mixer to medium speed and continue mixing until everything is blended into a cookie dough.

Adding the dry ingredients gradually helps incorporate them evenly without adding everything at once.

Step 6: Fold in the Mermaid Baking Chips and Sprinkles

Once your cookie dough is ready, remove the mixer.

Add the mermaid-themed baking chips and sprinkles to the dough. Using a wooden spoon or rubber spatula, gently stir until the colorful additions are distributed throughout.

This is what gives the cookies their signature funfetti appearance.

Rainbow sprinkles are a great choice for this recipe, although nonpareils or other available sprinkles can also be used.

Step 7: Scoop the Cookie Dough

Take your prepared baking sheet and a medium-sized cookie scoop.

Scoop portions of cookie dough onto the parchment-lined baking sheet. Arrange them approximately 2 inches apart so there is space between each cookie.

Continue until you have portioned the dough onto the baking sheet.

Step 8: Bake the Cookies

Place the baking sheet into your preheated oven at 375°F (190°C).

Bake the cookies for approximately 8–10 minutes.

Watch for the visual signs that indicate they are ready:

  • The edges should be lightly browned.
  • The tops should look puffy.
  • The tops should be set.

Once these signs appear, remove the cookies from the oven.

Step 9: Cool Before Serving

After removing the cookies from the oven, allow them to rest on the baking sheet for 5 minutes.

This gives them time to cool slightly before you move them.

Next, carefully transfer the cookies to a cooling rack and allow them to cool completely.

Once cooled, your Mermaid Funfetti Cookies are ready to enjoy!

Tips and Variations for Mermaid Funfetti Cookies

A few details from the recipe can help you prepare and store these cookies successfully.

Choose Your Favorite Baking Chips

Mermaid-themed baking chips are the main colorful addition to this recipe. Michaels carries a variety of baking chip colors, so you can choose from the available options when preparing your cookies.

Experiment with Different Sprinkles

Rainbow sprinkles work best for these cookies, but you don’t have to limit yourself to one type. Nonpareils or other available sprinkles can also be used.

The sprinkles are mixed directly into the dough, so choose a variety that you enjoy seeing throughout your cookies.

Make Sure the Butter Is Softened

The recipe calls for unsalted butter softened to room temperature. This is important when creaming it together with the granulated and brown sugars.

Also, remember to bring the egg and additional egg yolk to room temperature before mixing.

Keep an Eye on Baking Time

The recommended baking time is 8–10 minutes. Rather than relying only on the timer, look for lightly browned edges and puffy, set tops.

Allow the cookies to cool on the baking sheet for five minutes before transferring them to a cooling rack.

How to Store Mermaid Funfetti Cookies

If you have leftover cookies, storing them properly will help keep them ready to enjoy later.

At Room Temperature: Store the cookies in an airtight container at room temperature for up to 1 week.

Freezing Baked Cookies: These cookies can be frozen in an airtight container for up to 3 months.

Freezing Unbaked Cookie Dough: You can also prepare the dough portions ahead of time and freeze them before baking.

Here’s how:

  1. Scoop the cookie dough onto a parchment-lined baking sheet.
  2. Place the baking sheet in the freezer.
  3. Freeze the dough portions until solid, approximately 1 hour.
  4. Transfer the frozen cookie dough portions into a plastic freezer bag.
  5. When you’re ready to bake, place the frozen dough portions onto a baking sheet.

There is no need to thaw the frozen cookie dough before baking. Simply add a few additional minutes to the baking time.

Serving Suggestions

Once your Mermaid Funfetti Cookies have cooled completely, they’re ready to serve.

Their colorful baking chips and sprinkles make them a fun dessert to share with family and friends. You can arrange them on a serving plate or include them as part of a dessert selection.

They are also convenient to prepare ahead of time because the recipe includes instructions for freezing both baked cookies and unbaked dough portions.

Whether you serve them immediately after baking or prepare them for another day, these cookies offer a colorful twist on a classic sugar cookie.
