Instructions

Prepare the cake:

  • Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan.
  • In a large bowl, whisk together the flour, sugar, baking soda, baking powder, and salt.
  • In another bowl, mix together the vegetable oil, cooled brewed coffee, applesauce, and vanilla extract.
  • Pour the wet ingredients into the dry ingredients and mix until just combined.
  • Pour the batter into the prepared baking pan and spread it evenly.
  • Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
  • Remove from the oven and let the cake cool completely in the pan.

Prepare the coffee soak:

  • In a small bowl, mix together the brewed coffee and coffee liqueur (if using).

Prepare the "mascarpone" frosting:

  • Drain the soaked cashews and rinse them thoroughly.
  • In a food processor or blender, combine the soaked cashews, coconut cream, maple syrup, lemon juice, vanilla extract, and salt.
  • Blend until smooth and creamy, scraping down the sides as needed. Adjust sweetness to taste by adding more maple syrup if necessary.

Assemble the cake:

  • Once the cake has cooled, use a fork to poke holes all over the top of the cake.
  • Pour the coffee soak evenly over the cake, allowing it to soak in.

Frost the cake:

  • Spread the prepared "mascarpone" frosting evenly over the soaked cake.

Chill and serve:

  • Dust the top with cocoa powder.
  • Refrigerate the cake for at least 1-2 hours before serving to allow the flavors to meld together.
  • Slice and serve chilled. Enjoy your dairy-free and egg-free Tiramisu Sheet Cake!
