1
Make the spongecake.

In a bowl, add the egg whites.

While mixing with a hand mixer, add the sugar a little bit at a time until completely foamy.
-
4
Switch to a rubber spatula.
-
5
Add the egg yolk and roughly mix in.
-
6
Divide the sifted flour into 4-5 batches and fold in.

10
Heat up in the microwave.

11
Add a little bit of the batter from Step 3 and mix.

12
Add the mixture from Step 4 into the bowl and mix well.
-
13
The finished batter should drip like a ribbon.
-
14
Line the pound cake pan with parchment paper and pour in the batter.
-
15
Hit the bottom of the pan 2~3 times to get rid of the air.
-
16
Bake for 20-25 minutes in a 170C oven.
-
17
When it has finished baking, immediately drop the pan from a high place to get rid of the air.

18
Remove from the pan upside down and cool without removing the paper.
-
19
Remove the darkened surfaces with a knife.
-
20
Slice into 3 even pieces.
-
21
Since it's a pound cake shape, I think it will be easy to slice.
-
22
It will be pretty thin.
-
23
Add the Creme Chantilly ingredients to a bowl and whisk.

24
When foamy, add the 30 g of sweet potato for the Creme Chantilly.

26
Dissolve the sugar and set aside to cool.

Then coat with heavy cream and place the middle sponge cake on top.
-
29
Coat this layer with syrup.
-
30
Spread on some heavy cream and arrange 2 thinly sliced candied chestnuts.
-
31
Put enough cream on to cover the chestnuts and top with the last sponge cake.
-
32
Coat with syrup, spread the heavy cream, and let cool in the refrigerator.
-
33
Make the sweet potato cream.
-
34
Boil the potatoes in a pot until soft.

35
While hot, add the sugar, milk, and rum.
-
36
Mash together.

37
Strain with a net, or similar item.

The potato paste is finished.

After the potato paste has completely cooled, add the creme chantilly and with a rubber spatula, mix well.

The Mont Blanc cream is finished.

Attach a Mont Blanc decorating tip to a pastry bag and pipe a good amount onto the top of the cake.
