# Components:

→ Cupcakes

01 - 1 1/4 cups all-purpose flour
02 - 1/2 cup unsweetened cocoa powder
03 - 1 cup granulated sugar
04 - 1/2 teaspoon baking soda
05 - 1/2 teaspoon baking powder
06 - 1/4 teaspoon salt
07 - 2 large eggs
08 - 1/2 cup whole milk
09 - 1/2 cup vegetable oil
10 - 2 teaspoons vanilla extract
11 - 1/2 cup hot water

→ Buttercream Frosting

12 - 1 cup unsalted butter, softened
13 - 3 cups powdered sugar, sifted
14 - 2 tablespoons milk
15 - 2 teaspoons vanilla extract
16 - Food coloring (gray, pink, black)

→ Decorations

17 - 24 mini chocolate chips
18 - 12 pink candy-coated chocolates or jelly beans
19 - 24 thin pretzel sticks
20 - 24 almond slices
21 - 12 licorice laces or sour belts, cut into 3-inch strips

# Method:

01 - Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
02 - In a spacious mixing bowl, thoroughly whisk together the all-purpose flour, unsweetened cocoa powder, granulated sugar, baking soda, baking powder, and salt.
03 - In a separate bowl, beat the eggs, whole milk, vegetable oil, and vanilla extract until they are well combined. Gradually incorporate the wet ingredients into the dry ingredients, ensuring a thorough mix. Stir in the hot water until the batter achieves a smooth consistency.
04 - Distribute the batter evenly among the prepared cupcake liners. Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool completely.
05 - For the buttercream, beat the softened unsalted butter until it becomes creamy. Gradually add the sifted powdered sugar, mixing well after each addition. Incorporate the milk and vanilla extract, then beat until the frosting is light and fluffy.
06 - Divide the buttercream frosting into three separate bowls. Tint the majority of the frosting gray for the rat's bodies, a smaller portion pink for noses and ears, and a minimal amount black for fine details.
07 - To assemble the rat shapes, generously mound the gray buttercream onto each cooled cupcake. Sculpt the frosting into a slightly elongated shape to represent the rat's body, and form a smaller mound at one end for the head.
08 - Attach almond slices to the head area to serve as ears, positioning mini chocolate chips for eyes and pink candies for noses. Apply a small amount of the pink buttercream to accentuate the ears and noses.
09 - Insert pretzel sticks into the sides of the head to create whiskers. Secure the licorice lace or sour belt tails at the rear of the cupcake bodies. Use the black buttercream to pipe any additional facial details if desired.
10 - Chill the decorated cupcakes for 10 to 15 minutes to allow the decorations to set firmly before serving.

# Expert Advice:

  • Perfect centerpiece for quirky birthday parties
  • Customizable decorations let you adjust the cuteness factor
  • Uses simple ingredients you likely have in your pantry

02 -
  • These cupcakes can be prepared a day ahead without decorations
  • The contrast between chocolate cake and vanilla buttercream creates perfect flavor balance
  • The decorating process is kid friendly and makes for a fun activity
  • Each rat can be given unique expressions by slightly varying eye and whisker placement
03 -
  • Always start with completely cooled cupcakes—even slightly warm ones will melt your buttercream. For extra stability when decorating, chill the frosted cupcakes for 10 minutes before adding the decorative elements.
  • The consistency of your buttercream is crucial—too soft and your rats will look melted, too stiff and you'll struggle with smooth shaping. If you live in a warm climate, add an extra 1/2 cup powdered sugar to stabilize the frosting.
  • For professional-looking results, use a small offset spatula dipped in hot water and dried between strokes to smooth the buttercream body. This creates a sleek finish that makes the whimsical design look intentional rather than messy.
