Ingredients
  

For the Cake:

  • 2 cups all-purpose flour
  • 1 ¾ cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 1 ½ tsp baking powder
  • 1 ½ tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup hot water or brewed coffee for richness

For the Caramel Filling:

  • 1 cup granulated sugar
  • 6 tbsp butter unsalted
  • ½ cup heavy cream
  • Pinch of salt

For the Crunch Layer:

  • ¾ cup crushed toffee bits like Heath or caramelized nuts
  • Optional: finely chopped pretzels or brittle

For the Ganache Topping:

  • 1 cup semi-sweet chocolate chips
  • ½ cup heavy cream
  • 1 tbsp butter optional, for shine

Instructions
 

Make the Cake:

  • Preheat oven to 350°F (175°C). Grease and line cake pans with parchment paper.
  • In a large bowl, whisk together flour, sugar, cocoa, baking soda, baking powder, and salt.
  • Add eggs, buttermilk, oil, and vanilla. Mix until smooth.
  • Carefully stir in the hot water or coffee until well combined (batter will be thin).
  • Divide batter evenly between the pans.
  • Bake for 28–32 minutes, or until a toothpick comes out clean.
  • Let cool in pans for 10 minutes, then transfer to a cooling rack.

Make the Caramel:

  • In a saucepan over medium heat, melt sugar while stirring constantly.
  • Once melted and amber-colored, stir in butter until melted.
  • Slowly pour in heavy cream (careful—it’ll bubble!), whisking until smooth.
  • Add salt and let cool to room temperature.

Make the Ganache:

  • Heat cream in a saucepan or microwave until hot but not boiling.
  • Pour over chocolate chips in a bowl. Let sit 1 minute.
  • Stir until smooth. Add butter for extra shine.

Assemble the Cake:

  • Place first cake layer on a cake stand.
  • Spread a layer of caramel, then sprinkle crunch bits over it.
  • Repeat with second layer.
  • Place third layer on top and spread ganache over the top and sides.
  • Drizzle extra caramel and sprinkle more toffee or crunch bits on top.

Notes

Tips:

  • Chill the cake slightly before slicing for cleaner layers.
  • Add sea salt flakes on top for a sweet-salty twist.
  • Store leftovers covered in the fridge for up to 4 days.
