Sea Turtle Cookies
I had a vision for these cookies after talking to my niece. We were talking about some of our favorite animals as she enjoyed a marshmallow from her S’mores Kit, and she brought up sea turtles. So why not combine the two to make these adorable Sea Turtle Cookies! Not only are these cookies adorable, but they are so delicious. It combines a chewy graham cracker cookie and a homemade marshmallow. I hope that you enjoy this recipe as much as I do, and please tag me on social media if you’re ever recreating one of my recipes :) It brings me so much joy!

Recipe Tips
- Use a Candy Thermometer
- Getting the sugar mixture to exactly 242°F–245°F is essential for fluffy marshmallows that hold their shape.
- Work Quickly with Marshmallow
- Homemade marshmallow sets fast. If it becomes too thick while piping, microwave it for a few seconds to loosen it up again. I had to do this a few times to eep the marshmallow at a consistency that’s easier to work with
- Chill the Candy Melt Pieces
- Refrigerating the candy melt decorations makes them easier to remove from the parchment paper without breaking.
- Don’t Overbake the Cookies
- The graham cracker cookies should stay soft and chewy. Pull them from the oven once the edges are lightly golden.
- Use Silicone Molds
- Silicone molds make removing the marshmallow shells incredibly easy and help create the turtle shell texture.

How to Store Sea Turtle Cookies
Room Temperature
Store Sea Turtle Cookies in an airtight container at room temperature for up to 3 days.
Refrigerator
For longer freshness, refrigerate the cookies for up to 1 week. Allow them to come to room temperature before serving for the best texture.
Freezing
You can freeze the graham cracker cookies separately for up to 2 months. However, assembled cookies with marshmallow shells may lose texture after thawing.
Tips for Making Homemade Marshmallows
- Bloom the Gelatin Properly
- Letting the gelatin sit in water for at least 10 minutes ensures smooth marshmallows without lumps.
- Add Hot Sugar Slowly
- Pouring the sugar syrup too quickly can scorch the gelatin or create clumps.
- Whip Until Thick and Glossy
- The marshmallow mixture should become bright white, fluffy, and nearly triple in size before piping.
- Dust Everything with Powdered Sugar
- Powdered sugar prevents sticking and makes handling marshmallows much easier.
