DIY Clam Cookies for Under the Sea Theme Party

My sister threw a kick butt underwater birthday party for my niece, Chesney. She transformed a room into an under the sea setting that impressed everyone.

We are currently in the discussion phase of doing the same to our office. We believe our productivity will increase by far if we feel closer to our natural habitat – the ocean.

You know, since we are both truly not-so-secret mermaids. 😉

If you are throwing an under the sea theme party, please check with your guests about allergies before making these cookies.

Nutter Butter Cookies contain peanut butter, so they are a hard no for any guests that have peanut allergies.

An extra bonus with these clam cookies is that they are no bake. No need to tie up the oven to make these treats. They also make a great activity for party guests.

Have them decorate their own clam cookie for some creative fun.

How to Make No-Bake Clam Cookies



  1. Use a knife to scrape off the peanut butter filling inside the cookies
  2. Cut the tip off the decorating bag and place a tip inside
  3. Fill the decorating bag with the pink frosting
  4. Squeeze a good amount of frosting onto one cookie half and then place the other cookie half on top but carefully push down on the back
  5. Place a pearl Sixlet into the frosting
  6. If you are using candy eyes, stick them on with frosting
  7. If you are using white M&M’s, stick them on with the gel frosting and place a dot of gel frosting on the center of each white M&M
