Fruity Pebbles Whoopie Pies are a playful and fruity spin on a classic dessert. Marshmallow buttercream and Fruity Pebbles “sprinkles” make them irresistible.
Servings 16 whoopie pies
Ingredients
For the Whoopie Pies:
- ½ cup butter flavored shortening
- 1 cup granulated sugar
- 1 egg
- 2 teaspoons vanilla extract
- ½ cup buttermilk
- ½ cup hot water
- 2 ½ cups all-purpose flour
- 1 ½ teaspoons baking soda
- ½ teaspoon salt
- 1 cup Fruity Pebbles lightly crushed
For the Marshmallow Buttercream:
- ¾ cup unsalted butter room temperature
- 1 ¼ cups powdered sugar sifted
- 2 teaspoons vanilla extract
- 1 7- ounce container marshmallow cream
For the Garnish
- ½ cup Fruity Pebbles lightly crushed
Instructions
For the Whoopie Pies:
- Preheat the oven to 400°F. Line baking sheets with parchment paper.
- In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with an electric mixer, cream together the shortening and sugar until light and fluffy.
- Add in the egg, vanilla, buttermilk, and water and mix until the ingredients are fully incorporated.
- In a medium bowl, whisk together the flour, baking soda and salt. Slowly add the dry ingredients to the shortening mixture and mix until just combined. Use a rubber spatula to gently fold the Fruity Pebbles into the batter.
- Use a medium cookie scoop (1.5 tablespoons) to drop batter onto prepared cookie sheets about 2 inches apart.
- Bake for 8-9 minutes in the preheated oven.
- Allow cakes to cool on baking sheets for 5 minutes before removing to wire racks to cool completely.
For the Marshmallow Buttercream:
- In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed for 3-4 minutes.
- Turn the mixer down to low speed and gradually add in the powdered sugar until thoroughly combined. Turn the mixer back up to medium-high speed and mix for 5 minutes.
- Add in the vanilla extract and marshmallow cream and beat an additional 2 minutes.
To Assemble the Whoopie Pies:
- Spoon or pipe the buttercream onto the flat sides of half the cakes and top with remaining cakes.
- Roll the sides of the whoopie pies into Fruity Pebbles to garnish
Notes
- The marshmallow buttercream will generously fill 16-18 whoopie pies. If you prefer less filling, I would recommend cutting the recipe in half.
- To lightly crush the Fruity Pebbles, place them into a ziptop and gently crush the cereal pieces with your hands.
