To create the Peppermint Mocha Cake, follow these straightforward steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt until well combined.

3. Combine Wet Ingredients: In a separate bowl, mix the hot brewed coffee, vegetable oil, buttermilk, eggs, and peppermint extract until smooth.

4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until the batter is smooth and well blended.

5. Fold in Chocolate Chips: Gently fold in the semi-sweet chocolate chips to incorporate them evenly throughout the batter.

6. Divide and Pour Batter: Evenly divide the batter between the prepared cake pans, ensuring they are filled equally.

7. Bake: Place the pans in the preheated oven and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.

8. Cool the Cakes: Remove the cakes from the oven and let them cool in their pans for 20-25 minutes. Then carefully transfer them to wire racks to cool completely.

9. Frost the Cake: Once cooled, frost with your favorite chocolate frosting or cream cheese frosting, if desired.

10. Garnish: Sprinkle crushed peppermint candies on top for a festive touch, adding both flavor and visual appeal.
