How to Decorate Poop Emoji Cupcakes Step by Step

In this post I’ll show you a simple, kid-approved way to decorate poop emoji cupcakes. Combining chocolate cupcakes, creamy frosting, and a playful poop emoji face is an instant hit at children’s parties. The design is silly, easy to make, and guaranteed to get big laughs and excitement from little guests.

The best part is how flexible the idea is: once you know how to make fondant eyes and mouths, you can adapt the faces, sizes, and expressions to match any theme or party color scheme. These cupcakes are quick to assemble and make a memorable centerpiece for birthdays or casual get-togethers.

I surprised my daughter Emily with these and she absolutely loved them — the reaction is part of the fun. Below is an easy six-step method to create the poop emoji eyes and smiling mouths using fondant and a single piping tip.

You will need

• White fondant
• Black fondant
• Large circle piping tip (Wilton #12 recommended)
• Cornstarch (for dusting nonstick surface)
• Small rolling pin
• Sharp knife or small fondant cutter
• Small paintbrush or cotton swab and a little water (to attach pieces)

Step 1:

Begin by rolling the white fondant to about 1/8″ (approx. 3 mm) thickness on a surface dusted lightly with cornstarch to prevent sticking. Use the wide end of the large circle piping tip as a cutter to stamp out even white circles. These will become the whites of the eyes and additional white pieces for mouths.

Step 2:

Gently shape each white circle into an oval by squeezing the sides between your thumb and forefinger. This creates the classic emoji eye shape. Keep the ovals consistent so the eyes match when placed on the cupcake.

Step 3:

Roll the black fondant very thin—about 1/16″ (around 1–2 mm). Use the narrow side of the same piping tip to cut small black circles for the pupils. Cutting with the same tool ensures the black centers fit neatly onto the white ovals.

Step 4:

Use a tiny amount of water on a cotton swab or a small brush to lightly moisten the back of each black circle and press it onto the white oval to form the pupil. Use very little water to avoid colors bleeding—just enough to act like an edible glue. Allow the pieces to set for a few minutes before handling.

Step 5:

For the mouth, take extra white circles cut in Step 1. Gently roll each circle with the rolling pin into a small oval and then slice each oval down the middle to create two curved mouth shapes. These white mouths create a bright, friendly contrast against darker frosting.

Step 6:

Pipe your chocolate or brown frosting onto cooled cupcakes in a swirl that resembles the poop emoji shape. Position the fondant eyes and mouth on top of the frosting, pressing gently so they adhere. Adjust placement for expression—slightly tilted eyes or a wider mouth gives each cupcake personality.

Tips and variations

• Use cornstarch or powdered sugar sparingly to prevent sticking while keeping fondant smooth and pliable.
• Make eyes and mouths ahead of time and store them in an airtight container at room temperature for a day or two.
• Vary expressions by changing the angle of the eyes or cutting different mouth shapes (smile, grin, surprised).
• If you prefer edible glue with less moisture, use a small dab of corn syrup instead of water for stronger adhesion.
• Try different frosting techniques—smooth swirls or stacked cones—to mimic the emoji curl exactly.

With a little practice these poop emoji cupcakes come together quickly and deliver big smiles. They’re a fun, easy way to add personality to a kids’ party table or to brighten someone’s day with a cheeky treat.
