Dive into Creativity: Under the Sea Graham Crackers
Welcome back to another exciting installment of our Under the Sea Week celebration! We’re continuing our journey through delicious, ocean-inspired treats, and today’s creation promises to be a splash hit with children and adults alike.
If you’re in the midst of planning a birthday party or a special event, an under the sea theme is an absolutely fantastic choice – and frankly, a personal favorite! Imagine a vibrant world of aquatic creatures, shimmering blue decorations, and, of course, a table full of themed goodies. And if you do, consider this your official invitation, because there’s nothing I love more than a well-executed themed party!
Earlier this week, we unveiled our adorable Octopus Cupcakes. These charming treats require just a few simple ingredients: vanilla cupcakes, blue buttercream, large marshmallows, orange candy melts, and candy eyeballs. You can find the full recipe for those cute octopodes right here. Isn’t it fascinating that “octopi,” “octopodes,” and “octopuses” are all grammatically correct plural forms of octopus? Language is as deep and mysterious as the ocean itself!
Today, our focus shifts to the equally captivating Under the Sea Graham Crackers. So, grab your graham crackers, prepare your frosting, and get ready to create some of the cutest, most edible ocean scenes you’ve ever imagined!

The Easiest “Recipe” You’ll Ever Make: Under the Sea Graham Crackers
When it comes to these Under the Sea Graham Crackers, calling it a “recipe” almost feels like an overstatement. It’s more of an assembly project, a creative craft that happens to be utterly delicious. If I were making homemade graham crackers from scratch, perhaps it would warrant the full “recipe” title. But let’s be honest with ourselves – in our busy lives, very few of us are going to dedicate precious time to baking graham crackers when a perfectly good, uniform box of rectangles can be purchased for a few dollars. And there’s absolutely no shame in that!
This philosophy of simplicity extends to the frosting as well. There’s zero judgment from me if you opt for a store-bought blue frosting instead of whipping up your own blue buttercream. In fact, if I were juggling multiple cute treats for an under the sea themed party, I would wholeheartedly embrace every shortcut possible. The goal here is joyful creation and delicious consumption, not culinary competition. This approach makes these edible ocean treats accessible to everyone, regardless of their baking skill level or available time. It’s all about making memories and having fun!

What I cherish most about these Under the Sea Graham Crackers is their incredible simplicity. They are designed for ease, allowing kids to actively participate in the making process, which often makes eating them even more enjoyable! This edible craft is a fantastic way to encourage creativity, develop fine motor skills, and spend quality time together without the stress of complicated baking.
Gather Your Ocean-Inspired Ingredients
To create your stunning underwater graham cracker scenes, you’ll need just a handful of colorful and fun ingredients:

Having all your ingredients laid out before you begin will make the assembly process even smoother and more enjoyable, especially when crafting with eager little hands!

Under the Sea Graham Crackers
Equipment
-
Glass Mixing Bowl (for buttercream, if making from scratch)
-
Electric Mixer (optional, for buttercream)
-
Small bowl (for graham cracker crumbs/sand)
-
Butter knife or small offset spatula (for spreading frosting)
Ingredients
- Graham crackers (approximately 12 full crackers, broken into squares)
- Graham cracker crumbs (about ¼ cup, in a shallow bowl for dipping)
- Goldfish crackers (about 2-3 per graham cracker)
- White ball sprinkles (for bubbles)
- Green and red long sprinkles (or jimmies, for seaweed and crab legs)
- Round red sprinkles (for crab bodies)
Blue Buttercream (Yields enough for 12-15 crackers)
- ½ cup (113g) unsalted butter, room temperature (1 stick)
- ½ cup vegetable shortening (or use an additional ½ cup butter for an all-buttercream)
- 2 cups (227g) powdered sugar (confectioners’ sugar)
- Teal or blue food coloring (gel food coloring provides more vibrant color with less liquid)
Instructions
Part 1: Preparing Your Ocean Blue Buttercream
-
In a large mixing bowl, combine the room temperature butter and vegetable shortening. Beat the mixture using an electric mixer on medium-high speed for approximately 2 minutes, or until the mixture becomes visibly light, fluffy, and well-aerated. Scrape down the sides of the bowl as needed to ensure even mixing.½ cup (113g) butter, ½ cup vegetable shortening
-
Gradually begin to add the powdered sugar to the butter mixture, about 1 cup at a time. Start by slowly beating the mixture on low speed until the powdered sugar is mostly incorporated to avoid a sugar cloud. Once combined, increase the speed to medium and beat until smooth. Continue this process, adding enough powdered sugar until the frosting reaches your desired consistency – it should be thick enough to spread easily but not too wet or runny.2 cups (227g) powdered sugar
-
Add your desired amount of teal or blue food coloring. Mix the frosting by hand with a spatula until the color is completely even and streaks are gone. For a deeper ocean blue, add more food coloring a few drops at a time. If using store-bought frosting, simply mix in the food coloring until uniformly colored.teal or blue food coloring
Part 2: Assembling Your Under the Sea Graham Crackers
-
Take one full graham cracker. Using a butter knife or a small offset spatula, carefully spread a generous layer of your blue buttercream frosting onto almost the entire surface of the cracker. Leave a small, frosting-free strip at the very top edge of the graham cracker to represent the sky or horizon above the water.Graham crackers
-
Next, gently dip the very bottom edge of the frosted graham cracker into a small bowl containing graham cracker crumbs. This will create the sandy ocean floor effect. Ensure just the bottom portion of the cracker is covered with crumbs, resembling a beach or seafloor. If needed, you can lightly sprinkle extra crumbs by hand to fill in any sparse areas.Graham cracker crumbs
-
Now for the sea life! Carefully place two goldfish crackers onto the blue “ocean” frosting. Position them as if they are swimming. Then, give each goldfish two small white ball sprinkles above them to represent air bubbles rising to the surface. Gently press them into the frosting so they adhere.Gold fish crackers, White ball sprinkles
-
Add optional decorations to truly bring your underwater scene to life. To create swaying seaweed, use several long green sprinkles and arrange them vertically from the sandy bottom upwards into the blue frosting. For a cute little crab, place one round red sprinkle near the sandy bottom for the body, and then arrange several long red sprinkles around it to serve as its legs. Feel free to get creative with other sprinkles, small candies, or even crushed cookies for additional coral or rock effects!Green and red long sprinkles, Round red sprinkles
-
Repeat the process for remaining graham crackers. Serve immediately for fresh frosting, or store in an airtight container at room temperature for up to 2-3 days.
