Ingredients Needed for Mermaid Funfetti Cookies

Butter – I recommend unsalted butter but salted butter can still be used, but you may want to reduce the salt by ½ teaspoon. I prefer unsalted butter because it contains less water, so your cookies will spread less in the oven.
Granulated sugar – Granulated sugar adds sweetness but also makes for a crispier, chewier cookie so I don’t recommend reducing the sugar.
Brown sugar – Use light or dark brown sugar. Be sure to pack the sugar into your cup. If you ran out, make your own homemade brown sugar.
Eggs – Be sure to use room-temperature eggs so they blend in easily and do not seize up the butter in the bowl.
Egg yolk – If you like your cookies more on the chewy side, you will want to make sure to use egg yolks, not just egg whites.
Vanilla – You can use natural or artificial flavorvanilla. Or make homemade vanilla!
Flour – Be sure to measure the flour correctly. Stir the flour first, then spoon the flour into your cup and level it off. Do not pack it down. You can also measure by weight with a kitchen scale for the best accuracy.
Baking powder – This helps the cookies rise. Do not confuse it with baking soda. Baking soda and baking powder will not react the same way and is used for different baking purposes.
Salt – This helps to balance the sweetness from the sugar. I prefer fine sea salt, but you can also use table salt (use a little less if using table salt) or kosher salt (use a heaping teaspoon).
Corn starch – Corn starch is really important. This makes the cookies soft. Do not skip this!
Mermaid-themed baking chips – These are multicolored baking chips that have a white chocolate, vanilla flavor. You can substitute with white chocolate chips if you want to.
Rainbow sprinkles – I used mermaid rainbow-colored jimmies. Feel free to substitute with whatever colors you want.

How to Make Mermaid Funfetti Cookies

Preheat and prepare the baking sheet.

Preheat oven to 375^oF (190^oC). Line the baking sheet with parchment paper.

Combine dry ingredients.

In a medium mixing bowl, whisk together the flour, baking powder, salt, and corn starch. Set aside.

Mix butter and sugar.

Using a hand mixer or stand mixer with paddle attachment, cream together butter, brown sugar and granulated sugar on medium high speed until light and fluffy, about 2 minutes.

Add in egg, egg yolk, and vanilla.

Add egg (including the egg whites and egg yolk), egg yolk, and vanilla to your butter, brown sugar (natural or artificial flavor), and granulated sugar mixture. Make sure to mix until well combined.

Combine wet mixture of ingredients and dry mixture.

Gradually add in dry ingredients (don’t forget the corn starch) a little at a time to the wet mixture and mix on a low to medium speed just until combined, then increase to medium speed until all ingredients are blended. Do not overmix. Once the last of the flour has been mixed in, stop mixing.

Add sprinkles and baking chips.

Using a wooden spoon or a rubber spatula stir in sprinkles and rainbow chips.

Scoop dough onto baking sheet.

Using a medium size cookie scoop, drop dough onto lined baking sheet, about 2 inches apart.

Bake.

Bake for 8-10 min or until the edges of the cookies are lightly browned.

Allow cookies to cool.

Remove from the oven and allow the baked cookies to cool for 5 min on the baking sheet before transferring to a cooling rack to cool completely.

Recipe Tips

Make sure your eggs are at a room temperature – Place your eggs in a bowl of warm water for 10 minutes before using. Cold eggs will not incorporate easily into batter or the dough and will seize up the creamed butter.
Use a cookie scoop for cookies to bake evenly – Use a cookie scoop to scoop your cookie dough. Even-sized cookie dough balls will all bake up the same if you use a cookie scoop, so no unevenly baked cookies!
Bake the cookies on the center rack – Make sure your cookie sheet is placed onto the center rack of your oven and set to 350oF. If the cookies are baked on the top rack or lower rack of the oven, the tops or bottoms of the cookies may burn.
Cookies should be soft in the middle when done baking– When the timer goes off, the edges of the chocolate mint cookies should be set, and soft in the middle. They will continue to bake up and set as they cool.
Place more sprinkles and baking chips on top of the cookies when done baking. As soon as the cookies come out of the oven I place a few extra sprinkles and colorful baking chips on top of the cookies before they set to make for a pretty presentation.
Cool on a wire rack. You do not want to let your rainbow cookies continue to sit on the baking sheet to cool. After five minutes be sure to transfer them to a wire rack to cool.

Recipe Variations

Mermaid Delight Bars: Transform the cookie dough into a luscious, gooey bar form. Spread the dough evenly in a baking pan and bake until golden brown. Cut into bars and indulge in a mermaid delight! You could also add royal icing or vanilla buttercream to top these bars.
Mermaid Ice Cream Sandwiches: Take your favorite mermaid cookies and pair them with a generous scoop of ice cream. Try my Homemade Vanilla Ice Cream Recipe or for a fun pop of color and flavor try my Cotton Candy Ice Cream. Simply sandwich the ice cream between two cookies, roll the edges in matching sprinkles, and freeze until firm.
Mermaid Funfetti Cookie Cake: Instead of baking individual cookies, transform the dough into a single, larger-than-life cookie cake. Press the dough into a round cake pan and bake until golden and set. Once cooled, frost the top of the cake with a smooth layer of mermaid-colored buttercream, and don’t forget to sprinkle generously with shimmering sprinkles. This will make a beautiful and whimsical birthday cake.

Recipe FAQs

Where can I purchase the colored baking chips?

Michaels carries a variety of colors of baking chips. You can also buy these baking chips on Amazon.

What type of sprinkles should I use?

Rainbow jimmies work best but you could also use non perils or any other type of sprinkles available.

Can I freeze these cookies?

Yes, you can freeze these baked cookies in an airtight container for up to 3 months. You can also freeze unbaked cookies. Scoop the cookies onto a parchment lined baking sheet and freeze solid, about 1 hour, and then transfer to a plastic freezer bag. When ready to bake, transfer to a baking sheet and bake. There’s no need to thaw. Add on a few additional minutes of baking time. Check out my Ultimate Freezer Baking Guide for all the help on freezing your baked goods!

How should these cookies be stored?

You should store these cookies at room temperature in an airtight container for up to 1 week.

Why did my cookies spread so much?

This probably means your butter was too soft. Your butter should be at cool, room temperature. You should be able to press your finger into the butter with some resistance.
