Instructions
- Make Hazelnut Mousse Filling: In a medium heat-proof bowl, add 1/3 cup white chocolate chips and 2 Tbsp cold heavy cream. Heat in the microwave for 30 seconds and let it rest for a minute. Stir until the white chocolate is fully melted and smooth. Add 2 Tbsp hazelnut paste or Nutella and mix well. Set aside.
- Whip Cream: In a separate bowl, combine the remaining 1/2 cup cold heavy cream, 1 Tbsp powdered sugar, 1/2 tsp vanilla extract, and a pinch of salt. Beat on high speed with a hand mixer until thick and able to hold its shape, about 1 minute.
- Fold Mousse: Gently fold the white chocolate hazelnut mixture into the whipped cream using a rubber spatula with slow, sweeping motions until smooth and fluffy. Cover with plastic wrap and refrigerate for at least 1 hour or up to 2 days to set.
- Prepare Chocolate Cupcake Batter: Preheat the oven to 350°F (175°C) and line a 12-cup cupcake pan with liners. In a heat-proof bowl, combine 3/4 cup milk, 1/3 cup chocolate chips, and 1 tsp espresso powder (optional). Heat in microwave for 1 minute or use a double boiler until chocolate melts. Whisk until smooth.
- Mix Dry Ingredients: Sift together 3/4 cup all-purpose flour, 3/4 cup granulated sugar, 1/3 cup cocoa powder, 1/2 tsp baking soda, and 1/2 tsp salt into the chocolate mixture. Stir until combined, scraping sides and bottom of the bowl.
- Add Wet Ingredients: Mix in 2 large eggs, 1/3 cup vegetable oil, 1 tsp white vinegar, and 1 tsp vanilla extract until the batter is smooth and evenly combined.
- Bake Cupcakes: Divide the batter evenly into the cupcake liners, filling each about 2/3 full. Bake for 17-19 minutes or until a toothpick inserted in the center comes out with a few moist crumbs. Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
- Make Chocolate Hazelnut Buttercream: Using a hand mixer on medium speed, beat 1/2 cup unsalted butter until smooth, about 30 seconds. Add 2 Tbsp hazelnut paste or Nutella, 1/2 tsp vanilla extract, and 1/4 tsp salt and mix on low speed until combined.
- Add Sugar and Cocoa Powder: Gradually add 1 1/2 cups powdered sugar and 1/4 cup cocoa powder, mixing slowly and scraping the bowl as needed.
- Incorporate White Chocolate Mixture: In a small heat-proof bowl, heat 1/3 cup heavy cream and 1/3 cup white chocolate chips in the microwave for 30 seconds. Let sit for a minute, stir until smooth. Slowly mix this into the frosting on low speed.
- Whip Frosting: Increase mixer speed to high and beat for 1-2 minutes until the frosting is fluffy and smooth. If frosting is too thick, add 1 Tbsp extra cream; if too thin, add more powdered sugar. Stir by hand for extra smoothness. Transfer to a piping bag fitted with a Wilton 1M tip.
- Fill Cupcakes: Core out the center of each cooled cupcake and pipe the prepared hazelnut mousse filling inside using a piping bag for ease.
- Frost Cupcakes: Pipe a large swirl of chocolate hazelnut buttercream on top of each filled cupcake using the Wilton 1M tip.
- Decorate: Drizzle melted white chocolate and warm Nutella over the frosted cupcakes. Sprinkle with shortbread cookie crumbs and top each with a mini Kinder Bueno bar. Serve and enjoy the decadent treat!
