Decadent Smith Island Cake

Follow our step-by-step guide on how to make Decadent Smith Island Cake.

1. Step 1

   To create a delicious cake with a rich chocolate icing, start by making the icing.

2. Step 2

   In a medium saucepan, combine heavy cream and light corn syrup over medium heat.

3. Step 3

   Stir frequently until the mixture just begins to simmer, then remove it from the heat.

4. Step 4

   Next, place chopped bittersweet chocolate in a large microwave-safe bowl.

5. Step 5

   Pour the hot cream mixture over the chocolate, sprinkle in a pinch of kosher salt, and let it sit for about two minutes.

6. Step 6

   After that, whisk everything together until it’s completely smooth.

7. Step 7

   Allow the icing to cool to room temperature for about an hour, then transfer it to the refrigerator to thicken and become spreadable, which should take around 45 minutes.

8. Step 8

   Remember to stir it halfway through for the best consistency.

9. Step 9

   While the icing is chilling, preheat your oven to 350°F (175°C).

10. Step 10

    Prepare nine 8 1/2-inch round disposable cake pans by greasing them with cooking spray, lining the bottoms with parchment paper, and giving the paper a light spray as well.

11. Step 11

    In a stand mixer fitted with the paddle attachment, beat softened butter at medium speed until it’s smooth and creamy, which should take about a minute.

12. Step 12

    Gradually add sugar and continue mixing until the mixture is light and fluffy, around three minutes.

13. Step 13

    Add the eggs one at a time, mixing just until each is incorporated, then stir in the vanilla extract.

14. Step 14

    In a separate bowl, whisk together flour, baking powder, baking soda, and salt until well combined.

15. Step 15

    Gradually add this dry mixture to the butter mixture, alternating with buttermilk in three batches.

16. Step 16

    Start and end with the flour mixture, mixing on medium speed until just combined.

17. Step 17

    Divide the batter evenly among the prepared pans, smoothing the tops with an offset spatula for a nice finish.

18. Step 18

    Bake the cakes in the preheated oven for 12 to 14 minutes, or until a toothpick inserted into the center comes out clean.

19. Step 19

    Once baked, let the cakes cool in the pans on a wire rack for about 10 minutes before turning them out onto the racks to cool completely, which should take around 20 minutes.

20. Step 20

    When the cakes are cool, place one layer on an 8-inch round cake board and spread about 1/3 cup of the chilled icing over the top using a small offset spatula.

21. Step 21

    Add another cake layer on top and repeat the icing process.

22. Step 22

    Continue layering and icing until all the layers are stacked.

23. Step 23

    Once you’ve finished, coat the top and sides of the cake with a thin layer of icing, then chill it in the refrigerator for an hour, reserving any leftover icing for later.

24. Step 24

    After the chilling time, set the cake on a wire rack over a rimmed baking pan.

25. Step 25

    Microwave the reserved icing at medium power in 30-second intervals, stirring in between, until it’s smooth and pourable, which should take about 60 to 90 seconds.

26. Step 26

    Pour the warm icing over the top of the cake in a slow, steady stream, starting from the center and moving outward to let it cascade down the sides.

27. Step 27

    Use a small offset spatula to smooth out the sides and fill in any gaps.

28. Step 28

    Finally, chill the cake in the refrigerator until the icing is set, which will take about an hour.

29. Step 29

    Once set, carefully transfer the cake to a serving plate and enjoy it at room temperature.
