Ingredients
  

Cupcake Batter

  • 1 1/2 cups all-purpose flour
  • 3/4 teaspoon baking powder
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup butter softened
  • 2/3 cup granulated sugar
  • 2 large eggs
  • 1 1/2 teaspoons vanilla extract
  • 1/4 cup vegetable oil
  • 1/4 cup milk
  • 1 box instant pistachio pudding 3.4-ounce
  • 1 can crushed pineapple 8-ounce, drained

Marshmallow Frosting

  • 3/4 cup butter softened
  • 1 jar marshmallow crème
  • 1 1/2 cups confectioners' sugar
  • 1/2 teaspoon vanilla extract
  • 1 tablespoon milk
  • Chopped pecans for garnish

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) to ensure even baking and good rise.
  • In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
  • In another bowl, cream together the softened butter and granulated sugar until light and fluffy.
  • Add the eggs one at a time, mixing well after each addition.
  • Stir in the vanilla extract, vegetable oil, and milk.
  • Add the instant pistachio pudding mix to the wet ingredients and mix until fully combined.
  • Slowly add the dry ingredients to the wet mixture, stirring gently until just combined.
  • Fold in the crushed pineapple, ensuring even distribution throughout the batter.
  • Line your cupcake pan with liners and fill each liner about two-thirds full with the batter.
  • Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center comes out clean.
  • Once baked, remove the cupcakes from the oven and let them cool in the pan for 5 minutes before transferring to a wire rack to cool completely.

Frosting & Finishing

  • While the cupcakes are cooling, prepare the frosting by beating the softened butter until creamy.
  • Gradually add the marshmallow crème, mixing until smooth.
  • Slowly incorporate the confectioners' sugar, followed by the vanilla extract and milk, beating until the frosting is light and fluffy.
  • Once the cupcakes are completely cool, generously frost each cupcake with the marshmallow frosting.
  • Sprinkle chopped pecans on top for a delightful crunch.

Notes

  • For added fiber, substitute half of the all-purpose flour with whole wheat flour.
  • Use a sugar substitute to reduce sugar content if desired.
  • Make vegan by using flax eggs, plant-based butter, non-dairy milk, and vegan pudding mix.
  • Store unfrosted cupcakes at room temperature in an airtight container; refrigerate once frosted.
  • Freeze unfrosted cupcakes wrapped tightly; thaw at room temperature before frosting.
