• Preheat your oven to 350 degrees Fahrenheit and line two cupcake tins with yellow or white cupcake liners. 
• Using a medium sized mixing bowl, mix together the cake mix, eggs, milk and vegetable oil until combined, about 2 minutes. 
• Scoop the cupcake batter into the prepared cupcake tins, filling each liner about ⅔ full with batter.
• Bake the cupcakes for 20-23 minutes or until the edges turn golden brown, the cupcakes bounce back when gently tapped and a toothpick inserted in the center comes out clean. 
• Carefully remove the cupcakes from the oven. Remove from the cupcake pan and allow to cool completely. 
• Once the cupcakes have cooled, prepare to decorate by mixing the vanilla frosting with yellow food coloring until you have a bright yellow color. You don’t have to be too exact with the color. 
• Place the yellow sanding sugar in a shallow bowl. Frost cupcakes with a smooth layer of frosting. 
• Dip the cupcake in the yellow sanding sugar and gently swirl it so that the frosting is completely covered in sugar.
• Repeat with each cupcake until all are frosted and coated with sugar. 
• Put the large candy eyes on 12 of the cupcakes and use the black and red decorating gel to pipe on your favorite emoji faces likes smiles, tongues sticking out, surprised faces and kissy faces. You can also use candy hearts as eyes or around the face, optional. 
• If you want to make a face that has lines for eyes, such as a winky face, you can omit the candy eyes and use the black decorating gel to pipe on the eyes instead.

For poop emoji

• Place the chocolate frosting in a piping bag with a Wilton 2A piping tip.
• Pipe a “Poop pile” onto each of the remaining cupcakes and then press two small candy eyes into the top half of it to make a Poop emoji.
