Sea Turtle Cupcakes
Ingredients
For the cupcakes
- 1 (15.25-ounce) vanilla or French vanilla cake mix
- 1 (3.4-ounce) instant vanilla pudding mix
- 1 cup whole milk
- ½ cup sour cream, room temperature
- ½ cup salted butter, melted and slightly cooled
- 3 large eggs, room temperature
- 2 teaspoons vanilla bean paste (or pure vanilla extract)
- ¼ teaspoon almond extract (optional)
- ¼ teaspoon kosher salt
For the buttercream
- 1 cup salted butter, softened
- 3½ cups powdered sugar
- 3 to 4 tablespoons heavy cream
- 1 teaspoon vanilla bean paste
- Blue gel food coloring
For decorating
- 24 Nilla Wafers
- 96 green M&M’s (4 per cupcake)
- 24 Peanut M&M’s (light green if available)
- Melted dark chocolate, for the eyes
Instructions
- Preheat the oven to 325°F. Line two standard muffin pans with 24 cupcake liners.
- In a large mixing bowl, whisk together the cake mix, pudding mix, and salt.
- Add the milk, sour cream, melted butter, eggs, vanilla bean paste, and almond extract. Mix on low speed until combined, then increase to medium speed and beat for about 2 minutes until smooth.
- Fill each cupcake liner about two-thirds full.
- Bake for 18 to 22 minutes, or until the tops spring back lightly when touched and a toothpick inserted into the center comes out with a few moist crumbs.
- Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely.
- For the buttercream, beat the softened butter for 3 to 4 minutes until very light and fluffy. Gradually beat in the powdered sugar. Add the heavy cream and vanilla bean paste, then continue beating for another 3 to 5 minutes until the frosting is smooth, fluffy, and almost whipped. Tint with blue food coloring until it resembles bright ocean water.
- Spread or pipe a generous dollop of frosting onto each cupcake.
- Place a Nilla Wafer in the center of each cupcake to create the turtle’s shell. Press four green M&M’s into the frosting around the cookie for the flippers. Add one Peanut M&M at the front for the head. Using a toothpick, dot two tiny eyes with melted dark chocolate.
