Instructions

Cake

  • Preheat oven to 350 degrees F. Prepare three 9-inch round cake pans with non-stick spray and/or parchment.
  • In the bowl of stand mixer with whisk attachment, add the granulated sugar and eggs and beat on high for 2-3 minutes.
  • Meanwhile, combine the hot water, cocoa powder, instant coffee, and salt. With mixer on lowest setting, add to sugar mixture.
  • With mixer still on low slowly add in flour, baking soda, and baking powder. Let mix to incorporate.
  • Add in oil, buttermillk, and vanilla extract. Scrape down sides and bottom of bowl as needed. Do not overmix.
  • Evenly pour batter into prepared pans and bake for 22 to 25 minutes, or until an inserted toothpick is removed clean.
  • Let cakes cool in pans for 10 minutes, then invert onto a wire rack. Let cakes cool to room temperature or place in fridge until ready to assemble.

Kahlua Whipped Cream

  • Place a clean stand mixer bowl with whisk attachment in the fridge for 15 minutes.
  • Remove bowl from fridge and place on mixer. Add cream and whip on high until soft peaks form.
  • Reduce mixer speed to low and slowly add in the confectioners' sugar, Irish Cream, Kahlua, and cornstarch.
  • Once everything is incorporated, turn mixer back to high and whip until stiff peaks form. Transfer to fridge until ready to assemble.

Ganache

  • In a medium microwave-safe bowl, combine chocolate chips and heavy cream. Microwave on high for 15 seconds at a time, whisking together with a fork after each interval. Once the chocolate has melted into a shiny, smooth sauce (about 45 seconds total) transfer to the fridge to cool for 15 minutes.

Notes

To Assemble:
Place the cool layer of cake on serving platter. Spread the top with 1/3 of the whipped cream. (If you want to pipe out the rope pattern, place whipped cream in a large pastry bag fitted with a 2C tip. Pipe circles on that are slightly overlapping around the cake.)
Drizzle 1/3 of the cooled ganache over the whipped cream. Sprinkle 1/3 of the chopped cookies. Add next layer of cake and repeat. Store in fridge until ready to serve.
