Instruction
Chocolate Cupcakes
- Preheat oven to 350° F. Line a cupcake pan with 12 cupcake liners.
- In a small bowl or a glass liquid measuring cup, stir together chocolate chips, cocoa powder, and boiling water until the cocoa powder is dissolved. Set aside to cool slightly.
- In a mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and salt.
- Pour the chocolate mixture into the dry ingredients and whisk until combined. Add the vegetable oil, eggs, and vanilla extract. Whisk until combined and smooth.
- Use a large cookie scoop to portion the cupcake batter into the cupcake liners, approximately ¾ full. Bake for 20 minutes or until the tops of the cupcakes bounce back slightly when touched.
- Remove from the oven and cool in the pan for 5 minutes. Transfer the cupcakes to a wire cooling rack to cool completely.
Chocolate Hazelnut Buttercream Frosting
- In a large mixing bowl or the bowl of a stand mixer fitted with a whisk attachment, add in room temperature butter. Whip the butter for 5 minutes on medium-high speed, scraping down the sides occasionally.
- Add the powdered sugar and mix on the lowest speed setting until fully combined.
- Add in chocolate hazelnut spread and continue to mix on low until combined.
- Continue to mix on low speed and add in vanilla extract and salt. Drizzle in heavy cream. Scrape the sides and bottom of the bowl.
- Turn the mixer to medium speed and whip for an additional 2-3 minutes. Scrape the sides of the bowl occasionally to ensure the frosting is well mixed.
Assembling the Chocolate Hazelnut Cupcakes
- Core the center of the cooled chocolate cupcakes with an apple corer. Plunge the corer ⅔ of the way into the cupcakes, twist, and remove. Use a piping bag filled with chocolate hazelnut spread to fill the center of the cupcakes.
- Use a piping bag fitted with a Wilton 1M piping tip to pipe the chocolate hazelnut buttercream frosting onto the cupcakes. Top each cupcake with a Ferrero Rocher candy.
