• Oil – Vegetable oil keeps the cupcakes moist.
• Water – As directed on the cake mix box or recipe below.

For the buttercream frosting:

• Butter – Unsalted butter, softened to room temperature.
• Salt – A pinch of kosher salt balances the sweetness.
• Milk – 2% or whole milk, or a non-dairy alternative.
• Powdered sugar – Confectioner’s sugar for a smooth frosting.
• Food coloring – Use purple, blue, green, and orange for a festive palette.
• Candy eyes – Small and large edible eyes to personalize each monster.

Step-by-step instructions

The complete ingredient list and printable recipe card appear below. Here’s a clear, photo-supported walkthrough to help you assemble and decorate the cupcakes.

Preheat the oven to 350°F and line cupcake tins with liners.

1. Mix the cake mix, eggs, oil, and water until smooth.
2. Divide batter evenly among liners, filling each about ½–⅔ full.

Bake 14–16 minutes, or until a toothpick comes out clean. Cool completely before decorating.

Meanwhile, make the frosting:

1. Beat butter and salt until smooth. Add half the powdered sugar on low, then the rest with about 2 tablespoons milk. Add more milk only if needed to reach a slightly stiff but spreadable consistency.

2. Divide the frosting into four bowls and tint each one purple, blue, orange, and green. Mix until fully blended.

3. Fit a piping bag with a grass tip (#233 or similar) and fill it about halfway with one color at a time. Pipe short “hair” dollops around the cupcake surface by placing the tip close to the cupcake, squeezing gently, and pulling away to create the tuft.

4. Work in rows from the outer edge toward the center until the cupcake is covered. The grass tip creates forgiving texture, so it’s easy to fill in sparse spots.

5. Add candy eyeballs of various sizes to each cupcake for personality. Continue re-bagging and piping with the remaining colors until all cupcakes are decorated.

Kitchen tools and equipment

Helpful tools to make decorating easier:

• Cupcake pans: Two 12-cup muffin tins.
• Cupcake liners: Prevent sticking and add a decorative touch.
• Stand mixer or hand mixer: For smooth batter and fluffy frosting.
• Wire cooling rack: For even cooling before decorating.
• Piping bags and grass tip (#233): To create the monster “hair.” Other tips can be used for different effects.
