  1. Preheat oven to 350°F (180°C). Spray an 8-inch square baking pan with cooking spray; line pan with parchment paper.
  2. In the bowl of a stand mixer fitted with the paddle attachment, beat 1⁄2 cup (113 grams) butter, granulated sugar, and brown sugar at medium speed until fluffy, 3 to 4 minutes, stopping to scrape sides of bowl. Add mashed banana, buttermilk, eggs, and 1 teaspoon (4 grams) vanilla, and beat until well combined.
  3. In a medium bowl, whisk together flour, baking powder, baking soda, and 1⁄2 teaspoon (1.5 grams) salt. With mixer on low speed, add flour mixture to butter mixture in two additions, beating until combined. Fold in chopped hazelnuts. Spoon batter into prepared pan.
  4. Bake until a wooden pick inserted in center comes out clean, 30 to 35 minutes. Let cool in pan for 15 minutes. Remove from pan, and let cool completely on a wire rack.
  5. In the bowl of a stand mixer fitted with the paddle attachment, beat Nutella, cream cheese, and remaining 1⁄4 cup (57 grams) butter at medium speed until creamy and no lumps remain, about 2 minutes. With mixer on low speed, add confectioners’ sugar, ½ cup (60 grams) at a time, beating until well combined and stopping to scrape sides and bottom of bowl as needed. Beat in remaining 1⁄2 teaspoon (2 grams) vanilla and remaining 1⁄4 teaspoon salt. Add cream, and beat at medium speed until light and fluffy, about 30 seconds. Spread frosting onto cooled cake. Garnish with chocolate shavings, if desired.
