Ingredients

250g digestive biscuits or graham crackers, crushed

90g unsalted butter, melted

2 eggs, room temperature

300g granulated sugar

240ml buttermilk

120ml vegetable oil

120g cocoa powder

240ml hot coffee

250g all-purpose flour

1 tsp baking soda

1 tsp baking powder

1/2 tsp salt

1 1/2 cups marshmallow fluff

200g dark chocolate, chopped

120ml heavy cream

Instructions

  1. Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking pan.
  2. In a large bowl, combine the crushed digestive biscuits or graham crackers with the melted butter until evenly coated.
  3. Add the eggs one at a time, mixing well after each addition.
  4. Stir in the granulated sugar, buttermilk, oil, cocoa powder, and hot coffee until smooth.
  5. In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
  6. Gradually fold the dry ingredients into the wet ingredients until just combined.
  7. Pour the batter into the prepared baking pan and bake for 30 minutes, or until a toothpick inserted into the center comes out clean.
  8. Allow the cake to cool completely.
  9. Spread marshmallow fluff evenly over the cooled cake.
  10. To make the ganache, heat the heavy cream until steaming and pour over the chopped dark chocolate. Let sit for 2 minutes, then stir until smooth.
  11. Pour the ganache over the marshmallow topping and spread gently.
  12. Slice and serve. Optionally toast the marshmallow topping lightly with a kitchen torch before serving.

Notes

Mini chocolate chips can be added to the batter for extra chocolate flavor.

Sprinkle crushed graham crackers on top for additional crunch and presentation.

Milk chocolate can be substituted for dark chocolate if a sweeter flavor is preferred.

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Warm individual slices in the microwave for 10–15 seconds for a gooey marshmallow texture.

The unfrosted cake can be frozen for up to 2 months.
