In this tutorial, you will learn how to decorate poop emoji cupcakes with simple fondant eyes and mouths. These playful cupcakes are fun, silly, and perfect for kids’ parties, emoji-themed celebrations, birthday treats, or any dessert table that needs a little humor.
Children already love chocolate cupcakes, creamy frosting, and cute decorations, but the poop emoji adds an extra layer of laughter. It is instantly recognizable, easy to recreate, and always gets a big reaction. When you combine rich chocolate frosting with expressive fondant eyes and a smiling mouth, you get a cupcake that is both funny and adorable.
The best part is that this cupcake decorating idea is simple enough for beginners. You do not need advanced cake decorating skills or expensive tools. With just white fondant, black fondant, a piping tip, and a few basic supplies, you can create clean, cartoon-style facial features that bring your cupcakes to life.
This step-by-step guide focuses on making the poop emoji eyes and mouth from fondant. Once the decorations are ready, you can place them on cupcakes that have been frosted in a tall swirl to resemble the classic emoji shape. It is a fun project to make before a party, or you can let older kids help cut and shape the fondant pieces.
If you want a dessert that makes everyone smile, these poop emoji cupcakes are a great choice. They are silly without being complicated, and they turn ordinary cupcakes into memorable treats. Follow the six easy steps below to make the fondant eyes and mouths, then add them to your frosted cupcakes for the perfect finishing touch.
You will need
- White fondant
- Black fondant
- Large round piping tip, such as Wilton #12
- Corn starch
- Small rolling pin
- Knife
Before you begin, lightly dust your work surface with corn starch. This helps prevent the fondant from sticking while you roll and cut it. Use only a small amount, because too much corn starch can dry the fondant and leave a powdery finish. If the fondant feels too firm, knead it gently in your hands until it becomes smooth and easy to roll.

Step 1:
Roll the white fondant to about 1/8 inch thick. Try to keep the thickness even so all of the eyes look consistent. Using the wide side of the round piping tip, cut out small circles from the white fondant. These circles will become the base of the poop emoji eyes.
If the fondant sticks inside the piping tip, gently push it out with the end of a clean tool or your fingertip. Cut as many circles as you need for your cupcakes, allowing two eyes for each cupcake. It is a good idea to cut a few extra pieces in case any shapes tear or dry out while you work.

Step 2:
Use your thumb and index finger to gently squeeze each white fondant circle into an oval shape. The poop emoji eyes are usually rounded but slightly stretched, so do not flatten them too much. Work slowly and lightly to keep the edges smooth.
Place the finished white ovals on a clean surface while you prepare the black fondant. If the fondant starts to feel sticky, dust your fingertips with a tiny bit of corn starch. If it begins to dry too quickly, keep the pieces loosely covered until you are ready to assemble the eyes.

Step 3:
Roll the black fondant to about 1/16 inch thick. It should be thinner than the white fondant because these pieces will sit on top as the pupils. Using the narrow side of the same piping tip, cut small black circles.
These black circles should fit neatly inside the white ovals without covering them completely. If you want the cupcakes to look extra expressive, you can place the black circles slightly off-center when attaching them. This gives the eyes a fun cartoon look and makes each cupcake feel unique.

Step 4:
Use a Q-tip or a thin food-safe brush dipped in a very small amount of water to attach the black fondant circles to the white ovals. The water acts like glue, but you only need a tiny touch. Too much water can make the black fondant bleed into the white fondant or cause the pieces to slide.
Lightly moisten the back of each black circle, then press it gently onto a white oval. Repeat until all of the eyes are assembled. Let the pieces rest for a few minutes so they become easier to handle before placing them on the cupcakes.

Step 5:
To make the mouth, use the extra white fondant circles you cut in Step 1. With the small rolling pin, gently roll each circle into a longer oval. Once the oval is shaped, cut it across the center with a knife. Each oval will create two small mouths.
Keep the cut clean and smooth so the mouths look neat when placed on the frosting. You can use a straight mouth for a classic emoji smile, or angle it slightly for a more playful expression. Small details like this make the cupcakes look lively and fun.

Step 6:
Add the fondant eyes and mouth to your piped cupcakes. For the best poop emoji cupcake look, place the decorations on a tall swirl of chocolate frosting. Press the fondant pieces gently into the frosting so they stay in place without sinking too deeply.
Arrange two eyes near the upper center of each cupcake and place the mouth below them. Once decorated, the cupcakes are ready to serve. These easy poop emoji cupcake decorations are simple, funny, and guaranteed to get attention at any kid-friendly celebration.
