Baking + Learning = Fun!
Here are some simple ways to turn your kitchen time into a hands-on learning adventure with these shark cupcakes:
- Measuring practice: Kids can scoop flour, level measuring cups, and pour ingredients into the bowl.

- Following steps and directions: Kids can help keep track of each baking step as you move from mixing to baking to decorating.
- Math: Counting and grouping. Count how many cupcakes are in the pan and group them onto serving trays.
- Creative thinking and storytelling: Kids can imagine what their shark is doing in the "water" while decorating their cupcake then create a fun story about it as they decorate the shark fin cupcakes.

How to Make Cute Shark Fin Cupcakes
Step 1: Preheat the oven to 350 degrees and place cupcake liners in a cupcake pan.
Step 2: Prepare the cupcake batter. If using boxed cake mix, mix according to the package directions. If making homemade cupcakes, whisk together the dry ingredients in a bowl, combine the wet ingredients in another bowl, then stir them together until a smooth batter forms.

Step 3: Scoop about ⅓ of the batter into a separate bowl. Add 1-2 small drops of blue gel food coloring and gently stir until the batter turns a soft ocean blue. Add another drop or two of blue gel food coloring to the smaller bowl so it's slightly darker.
Step 4: Spoon some light colored batter into the cupcake liners, then add a little of the darker blue batter on top. Use a toothpick or knife to lightly swirl the colors together. Fill the cupcake liners about two-thirds full with batter and bake for about 22 minutes, or until a toothpick inserted in the center comes out clean. Let the cupcakes cool completely.

Step 5: Make the frosting by beating the butter until smooth, then gradually mixing in the confectioners' sugar and cream until light and fluffy. Divide the frosting and tint one portion blue.
Step 6: Place blue and white into a piping bag with a star tip and pipe upward all along the cupcake then in the center. Insert shark fin into the top middle.
Substitutions & Variations
- Sprinkle blue sanding sugar over the frosting for a sparkly ocean look.
- Add gummy fish candies around the shark fin topper.
- Use ocean-themed cupcake liners to match the shark theme.
- Arrange the shark cupcakes close together on a tray to create a "shark water" display.

FAQs
Can I use boxed cake mix for shark cupcakes?
Yes. Prepare the cupcakes according to the box directions and decorate them once they have cooled.
What can I use for shark fin toppers?
You can use candy shark fins, fondant shapes, or small plastic cupcake toppers.
Why did my cupcakes sink?
Cupcakes can sink if they are underbaked, if the oven temperature runs low, or if the batter is mixed too much. Bake until a toothpick comes out clean and try to avoid opening the oven while the cupcakes are baking.
How do I get the two-color frosting look?
Add the blue and white frosting side by side in the piping bag before piping onto the shark cupcakes.
