    • 1 ½ teaspoons baking powder
    • 1 ½ teaspoons baking soda
    • 1 teaspoon salt  
    • 1 cup buttermilk

    • 2 large eggs
    • 2 teaspoons vanilla extract
    • 1 cup hot brewed coffee
  • For the Caramel Pecan Topping:
    • 1 cup (2 sticks) unsalted butter
    • 2 cups packed light brown sugar
    • ½ cup evaporated milk
    • 1 teaspoon vanilla extract
    • ¼ teaspoon salt
    • 2 cups chopped pecans
  • For the Chocolate Ganache:
    • 1 cup semi-sweet chocolate chips
    • ½ cup heavy cream

Instructions:

  1. Prepare the Cake:
    • Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
    • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
    • In a separate bowl, combine the buttermilk, vegetable oil, eggs, and vanilla extract.
    • Add the wet ingredients to the dry ingredients and mix until just combined.
    • Slowly pour in the hot coffee and mix until smooth. The batter will be thin.
    • Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
    • Let the cake cool completely.  
  2. Make the Caramel Pecan Topping:
    • In a medium saucepan, melt the butter over medium heat.
    • Stir in the brown sugar, evaporated milk, vanilla extract, and salt.
    • Bring to a boil, stirring constantly.
    • Reduce heat and simmer for 5-7 minutes, stirring occasionally, until slightly thickened.
    • Remove from heat and stir in the chopped pecans.
    • Pour the caramel pecan mixture over the cooled cake.
  3. Prepare the Chocolate Ganache:
    • Place the chocolate chips in a heat-proof bowl.
    • In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
    • Pour the hot cream over the chocolate chips and let it sit for 1 minute.  
    • Gently whisk until smooth and glossy.
    • Pour the chocolate ganache over the caramel pecan topping.
  4. Finish and Serve:
    • Let the ganache set for a few minutes before slicing and serving.
    • Enjoy!
