VIDEO RECIPE! Learn how to make these Under the Sea Graham Crackers!


Six Under the Sea Graham Crackers with blue buttercream and goldfish crackers on a wooden table. We’re back with another recipe for Under the Sea Week! If you’re getting ready to plan a birthday party, consider doing an under the sea theme – and make sure to invite me, because I love a good themed party :)

On Monday we shared a recipe for Octopus Cupcakes – all you need is vanilla cupcakes, blue buttercream, large marshmallows, orange candy melts and candy eyeballs! Get the recipe for those cute octopodes here. Isn’t is crazy that octopi, octopodes and octopuses are all plural forms of octopus? :)

Today we’re talking Under the Sea Graham Crackers, so get some graham crackers and frosting ready, because these are too cute!

Today’s “Recipe”

I feel like I can’t even call today’s Under the Sea Graham Crackers recipe a recipe. Maybe if I made my own homemade graham crackers from scratch it would feel more like a real recipe, but, let’s all be honest.. we’re not going to spend the time making our own graham crackers when we can purchase a box of perfect rectangles for under three bucks.

Also, there is no judgment you if you decide to use store bought blue frosting instead of making your own blue buttercream. If I was prepping other cute treats for an under the sea party, I would definitely save time where I could!

My Favorite Thing About These Under the Sea Graham Crackers

My favorite thing about these Under the Sea Graham Crackers is that they are incredibly easy to make. You’ll need graham crackers, graham cracker crumbs, goldfish, blue frosting, white ball sprinkles, red and green long sprinkles (also called jimmies) and red round sprinkles.

When you assemble them, you’ll start in the background, with the blue frosting and work your way to the foreground with all the little sea creatures.

Under the Sea Graham Crackers

Under the Sea Graham Crackers

Additional Time: 20 minutes
Total Time: 20 minutes


  • Graham crackers
  • Graham cracker crumbs, in bowl
  • Gold fish crackers
  • White ball sprinkles
  • Green and red long sprinkles, or jimmies
  • Round red sprinkles

Blue buttercream

  • 1 stick of butter, room temperature
  • 1/2 cup vegetable shortening (can use butter instead)
  • 2 cups powdered sugar
  • teal or blue food coloring


Blue Buttercream

  1. In a mixing bowl, combine the room temperature butter and shortening, beat using an electric mixer for 2 minutes, until light and fluffy.
  2. Begin to add in the powdered sugar, about 1 cup at a time. Slowly beat the mixture until the powered sugar is incorporated. Continue this process, adding enough powdered sugar to make sure the frosting isn’t too wet.
  3. Add in your desired blue food coloring, mix by hand until the color is even.

To assemble the under the sea graham crackers

  1. Take one graham cracker and using a spreader or butter knife, spread blue frosting on almost all of the cracker, but leave the very top of the graham cracker frosting free.
  2. Place the bottom of the frosted graham cracker into the bowl with graham cracker crumbs, covering just the bottom of the cracker with crumbs or ‘sand’. You can sprinkle extra crumbs on if needed.
  3. Add two goldfish crackers. Then give each goldfish 2 air bubbles, using the white ball sprinkles.
  4. Optional decorations include seaweed and a crab. To make the seaweed use several long green sprinkles and arrange them to look like seaweed. To make the crab, use one red round sprinkle and several long red sprinkles as legs and arrange them to look like a crab.

  31. This is so cute! how many ingredients would we need to make for 80 people? or how much does this one recipe make? I am planning to make these for a party!

    • Hi Ava! It really just depends on how much frosting you put on each graham – but I would suggest tripling the frosting recipe! You can also use butter in place of the vegetable shortening.
