Creating your Chocolate Hazelnut Pear Cake is simple if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, cocoa powder, ground hazelnuts, baking powder, baking soda, and salt until well combined.
3. Prepare Wet Ingredients: In another bowl, beat together the eggs, vegetable oil, buttermilk, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet ingredients to the dry mixture, stirring until just combined. Be careful not to overmix.
5. Add Pears: Gently fold in the diced pears and chocolate chips if using, ensuring they are evenly distributed throughout the batter.
6. Pour Batter: Transfer the cake batter into the prepared cake pan, smoothing the top with a spatula.
7. Bake: Place the pan in the preheated oven and bake for 40-50 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the Cake: Remove from the oven and let it cool in the pan for about 15 minutes. After that, carefully transfer to a wire rack to cool completely.
9. Dust with Powdered Sugar: Before serving, dust the top of the cake with powdered sugar for a beautiful finish.

By following these easy steps, you’ll create a delicious and moist Chocolate Hazelnut Pear Cake that will surely impress.
