How To Make Oyster Cookies

Oyster cookies are so incredibly easy to make and they are the perfect addition to an under the sea or mermaid party.

I made these for my daughter’s mermaid themed 3rd birthday party, with pink, white and blues. These oyster cookies were an absolute hit at the party and they looked oh so pretty!How To Make Oyster Cookies

How To Make Oyster Cookies

You can choose to either bake your cookies (recipe below if you wish) or pre-purchase if you can find something of the right shape.

If you make them, make sure that you cut using a cookie cutter to ensure that the cookies are all roughly the same size, which makes it easier when you try and pair the cookies to make the oysters.

Oyster Shell Cookies

Grab yourself some sixlets for the oyster pearl decoration and put them aside for now.


It’s time to make your buttercream!  We made the buttercream pink to fit in with the party colours, but you can really choose whatever colour your prefer.

Pink Buttercream

Add a small portion of buttercream onto the back of one of the cookies.

Tip: Don’t add too much otherwise it will all spill out when you try and create the oyster cookie!

Oyster Shell Cookies with Buttercream

Carefully lay your second oyster cookie on top of the buttercream, trying to keep the back of the cookies together as much as possible to help create the shell effect.

It may feel a bit squishy at the moment, but don’t worry as the buttercream will harden and attach better to the cookies once it has been in the fridge.

Once you are happy with how the oyster looks, add the sixlets pearl in the middle and finally brush lightly with some edible shimmer dust for that special oyster sea feeling.

They looked awesome on the party table and both the kids and adults loved them.

    These are perfect for a mermaid or under the sea party. We had a sharks and mermaid party earlier this summer, sure wish I knew about these!

      It’s such an awesome theme isn’t it Tracy! Adding sharks to the theme is an awesome idea….but I do love everything under the sea related. There is so much variation you can do….there is always room for another under the sea party and then you can add these oyster cookies 🙂
