Ingredients for Easy Monster Cupcakes

Here’s what you’ll need to make 24 bright and silly monsters. Most of this might already be in your pantry!

For the Cupcakes:

• 1 box chocolate cake mix
• 3 eggs
• ½ cup oil
• 1 ¼ cups water

For the Buttercream Frosting:

• 1 cup unsalted butter, softened
• 1 teaspoon salt
• 4 cups powdered sugar
• 3–4 tablespoons milk

And For the Decoration:

• Food coloring in purple, blue, green, and orange
• Candy eyeballs (use a mix of small and large)
• Piping bags
• #233 piping tip (the grass/hair tip—it’s perfect for monster “fur”)

Tip: No #233 tip? Use any star tip and pull to create texture. Imperfect hair = perfect monsters.

How to Make This Easy Monster Cupcakes Recipe

Now for the fun part! I’ll break it all down into simple steps, and sprinkle in some of my favorite tips along the way.

Step 1: Bake the Cupcakes

1. Preheat oven to 350°F (175°C).
2. Line two standard cupcake pans with liners (24 total).
3. In a large bowl, combine the cake mix, eggs, oil, and water.
4. Mix on low speed for 1 minute, then on medium for another minute until smooth.
5. Fill each liner about ⅔ full.
6. Bake for 14–16 minutes, or until a toothpick comes out clean.
7. Let cool completely before decorating.

Personal tip: If you’re baking with kids, let them help with mixing—but definitely keep an eye on the egg cracking… trust me on that one.

Step 2: Make the Buttercream

1. Beat softened butter and salt in a large bowl until creamy.
2. Add half the powdered sugar. Mix on low until combined.
3. Add the rest of the powdered sugar and 2 tablespoons of milk.
4. Mix again, then increase speed to medium for 1 minute.
5. If too thick, add milk 1 tablespoon at a time until smooth and fluffy.

Real talk: I’ve made frosting too thick, too runny—you name it. Just play with it until it feels right.

And Step 3: Color the Frosting

1. Divide frosting evenly into four bowls.
2. Add food coloring: purple, blue, green, and orange.
3. Stir well until no white streaks remain.

I love gel food coloring for vibrant colors that don’t water down the frosting.

Step 4: Decorate Like a Monster Master

1. Fill a piping bag fitted with a #233 tip with your first frosting color.
2. Hold the bag ½ inch above the cupcake.
3. Gently squeeze to attach frosting to the cupcake, then pull away to make monster “fur.”
4. Start from the outside edge and work your way in.
5. Repeat until the whole top is covered in “hair.”

If your kids are helping, let them freestyle. One of mine made a monster with five eyes and a frosting mustache… it was iconic.

And Step 5: Add the Eyeballs!

Before the frosting sets, press candy eyeballs onto each cupcake.

• Use 1 big eye for a one-eyed monster
• Mix small and large for goofy expressions
• Go wild—this is where the personality shines!

Step 6: Rinse and Repeat

Swap the frosting color, clean your piping tip, and repeat with the next batch of cupcakes.

Once you’re done? Step back and admire your adorable monster army.

Let them chill for 15–20 minutes before serving so the frosting sets slightly. Bonus: easier to transport!

How to Customize Your Monster Cupcakes

One of the best parts of this monster cupcake recipe is how easy it is to make it your own.

Try these fun variations:

• Swap chocolate cake for vanilla, funfetti, or red velvet
• Use buttermilk instead of water for extra richness
• Add sprinkles or edible glitter for some sparkle
• Create a blue monster cake version with just blue frosting and LOTS of eyes

My daughter loves adding mini marshmallows as “teeth.” It’s weird. It’s wonderful.

FAQs About Monster Cupcakes

What’s the best frosting for monster cupcakes?
A classic American buttercream works best—it’s thick, holds its shape, and is easy to color.

Yes! Bake cupcakes up to 2 days ahead. Store unfrosted in an airtight container. Decorate the day you’re serving.

How do I get bright frosting colors?

Keep in an airtight container at room temp for 2–3 days. You can also refrigerate—but let them come to room temp before eating.
