Ingredients
  

The Master Vanilla Sponge
  • 1 ¾ cups unbleached all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon kosher salt
  • ½ cup unsalted butter 1 stick, softened to room temperature
  • 1 cup granulated sugar
  • 3 large eggs
  • 2 teaspoons pure vanilla extract
  • ¾ cup whole milk
The Chocolate-Hazelnut Core
  • ¼ cup unsalted butter ½ stick, softened to room temperature
  • ½ cup premium chocolate-hazelnut spread such as Nutella
  • ½ cup confectioners’ sugar
The Peanut Butter Cream Cheese Frosting
  • ½ cup unsalted butter 1 stick, softened to room temperature
  • 1 cup smooth peanut butter
  • 4 ounces cream cheese softened to room temperature
  • 2 cups confectioners’ sugar
  • 1 tablespoon whole milk optional, for consistency

Method
 

The Batter Architecture
  1. Preheat the oven to 350°F. Line a standard 12-cup metal muffin pan with high-quality paper liners.
  2. In a medium bowl, whisk together the all-purpose flour, baking powder, and kosher salt to ensure the leavening agents are perfectly distributed.
  3. In the bowl of an electric stand mixer, cream the softened butter and granulated sugar together on medium-high speed until pale and highly fluffy, about 3 minutes.
  4. Add the eggs one at a time, mixing thoroughly after each addition. Stir in the pure vanilla extract and the whole milk until unified.
  5. Reduce the mixer speed to low. Gradually pour in the dry flour mixture, mixing only until just combined to prevent overworking the gluten.
  6. Use a heavy-duty ice cream scoop to divide the batter evenly among the 12 muffin cups.
  7. Bake for 20 minutes, or until a wooden tester inserted into the center of a cupcake comes out perfectly clean. Cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
The Core Extraction & Filling
  1. In a medium bowl, use an electric hand mixer to beat the ¼ cup softened butter, chocolate-hazelnut spread, and ½ cup confectioners' sugar until perfectly smooth and glossy.
  2. Once the cupcakes are completely cool, use a small melon baller or a sharp paring knife to carefully scoop out the top-center of each cupcake (save the small cake "plugs").
  3. Transfer the hazelnut filling to a pastry bag fitted with a plain tip. Squeeze approximately 1 tablespoon of the rich filling directly into the hollowed core of each cupcake. Gently place the reserved cake plug back on top to seal the center.
The Emulsified Frosting
  1. In a large mixing bowl, use an electric mixer to beat the ½ cup softened butter, smooth peanut butter, and softened cream cheese until seamlessly combined and fluffy.
  2. Gradually add the 2 cups of confectioners’ sugar in batches, beating on low speed until smooth. (If the frosting is too stiff, add 1 tablespoon of milk to achieve a spreadable, silky consistency).
  3. Using an offset spatula or a piping bag fitted with a large star tip, generously frost the top of each sealed cupcake, fully covering the core, and serve.
