Black Sesame Icebox Cake

Steps

1. 1

   Whip the cream

   • Pour the 2 cups (480 ml) cold heavy cream into a chilled medium bowl.
   • Using an electric mixer on medium-high speed (or a whisk by hand), beat until soft peaks form—the cream should just hold its shape with peaks that gently fold over when the beaters are lifted.
   • This takes 3–4 minutes with a mixer.
   • Do not overmix or the cream will become grainy.

   Ready when: Soft peaks form when beaters are lifted

   Tip: Overwhipped cream will turn to butter; stop as soon as soft peaks hold.

2. 2

   Mix in black sesame and condensed milk

   • In a small bowl, gently warm the black sesame paste by stirring for about 30 seconds with a spoon.
   • Add the ⅓ cup (80 ml) condensed milk and ½ teaspoon (2.5 ml) vanilla extract to the sesame paste.
   • Stir until mostly smooth (a few tiny lumps are fine).
   • Fold this mixture into the whipped cream with a rubber spatula using 10–12 gentle motions until the color is evenly marbled with no large swirls of white.
   • The cream should be pale gray with black streaks.

   Ready when: Color is evenly marbled pale gray with black streaks

   Tip: Fold gently to keep the cream airy; overmixing deflates it and makes the cake dense.

3. 3

   Layer wafers and cream

   • Spread a thin layer of the black sesame cream (about ¼ inch / 6 mm thick) on the parchment-lined bottom of your 8-inch pan.
   • Arrange a single layer of vanilla wafers in a circle, overlapping slightly and fitting them snugly.
   • Spread another layer of cream (⅜ inch / 1 cm thick) over the wafers.
   • Repeat with alternating layers of wafers and cream until you reach the top of the pan, ending with a cream layer.
   • You should have 4–5 layers of wafers total.
   • Gently press down with an offset spatula as you build to compact the layers slightly.

   Ready when: All wafers and cream are layered evenly to the top of the pan

   Tip: Offset the wafers in each layer so they're not stacked directly on top of one another—this helps them soften evenly.

4. 4

   Chill and set

   • Cover the pan loosely with plastic wrap and refrigerate for at least 8 hours, preferably overnight (up to 24 hours).
   • The wafers will gradually soften as they absorb moisture from the cream, and the flavors will meld.
   • The cake should feel firm when pressed gently on top.

   Ready when: Top feels firm to the touch; wafers are no longer crisp

   Tip: Don't skip this step—the texture won't be right if the cake hasn't chilled long enough.

5. 5

   Unmold and garnish

   • Remove the cake from the refrigerator 10 minutes before serving to take the chill off slightly for easier slicing.
   • If using a springform pan, release and remove the ring.
   • Run a thin knife around the edge if using a regular pan, then invert onto a serving plate and peel away the parchment.
   • If you prefer, slice the cake while still in the pan and serve slices directly from the pan.
   • Sprinkle the top with black sesame seeds if using.

   Ready when: Cake is loose from the pan and ready to plate

   Tip: A warm, wet knife dipped in hot water and wiped clean between cuts creates neat slices.
