Easy Suggestions for Excellent Korean Candy Potato Cake
Why Purple Candy Potatoes Are a Recreation-Changer for This Cake
On this recipe, I used purple candy potatoes, also called Hawaiian or Okinawan candy potatoes. Their pure nuttiness and sweetness actually shine by, and the gorgeous pastel purple flesh they carry to the cake makes it a deal with for each the eyes and the style buds.
That stated, for those who can’t discover purple varieties, be happy to make use of no matter is on the market in your space (e.g., Beauregard candy potatoes). Nevertheless, I extremely advocate utilizing purple candy potatoes for the most effective expertise!
Sponge Cake Made Straightforward: Retailer-Purchased, Genoise, or Combine
To avoid wasting time, I used unfilled sponge desserts for this recipe, which I picked up from Woolworths—one of many main grocery shops in Australia. The pack comes with two unfilled sponge desserts for about AUD $6. You’ll simply want a cake leveler to divide them into 4 even cake bases. Many Koreans use an unfilled Genoise base that has already been level-cut.
In the event you’d moderately bake, you’ll be able to all the time make the sponge base from scratch or use a pre-mix vanilla cake. Personally, I just like the White Wings model—it tastes higher than a few of the different choices on the market.
For baking, I like to recommend utilizing tiered cake pans of the identical dimension to maintain issues easy. I used the Mondo Ombre/Layer Cake Pan Set (5 items), which has an 18cm (7-inch) diameter and a 3cm (1-inch) peak, and it labored completely. For reference, dividing one pre-mix cake combine evenly amongst three of those pans works very well.
Making Stabilized Whipped Cream
Usually, whipped cream for Korean candy potato cake is made utilizing heavy cream or thickened cream and icing sugar. I’m unsure how others handle to ice the cake completely with simply these two elements, however after many failed makes an attempt, I noticed that stabilizing the whipped cream is crucial for profitable adorning. I made a decision to make use of mascarpone (a creamy Italian cheese), because it holds up a lot better than whipped cream by itself.
For the most effective outcomes:
- Guarantee each your mascarpone and thickened cream are chilly—straight from the fridge. Chilly elements whip up quicker and create a stiffer, extra secure cream.
- Chill your mixing bowl and whisk beforehand to take care of the chilly temperature.
- Use a stand mixer or hand mixer on medium pace for smoother outcomes and to avoid wasting time. Cease whipping as quickly as stiff peaks type to keep away from over mixing.
- I’ve had success utilizing La Casa Del Formaggio Mascarpone (250g) from Woolworths and Montefiore Mascarpone (250g) from Coles. Within the U.S., a preferred possibility is BelGioioso Mascarpone, which is on the market in 8-ounce packages.
Stabilized whipped cream is finest used contemporary, despite the fact that it’s stabilized. Nevertheless, if wanted, you’ll be able to retailer it in an hermetic container within the fridge for as much as 24 hours. If it softens barely, give it a delicate whisk earlier than serving to revive its fluffy texture.
The way to Retailer Your Cake
For optimum taste, retailer the cake in a tall cake provider or hermetic container to take care of its form, and permit it to sit back within the fridge for just a few hours earlier than serving. For the freshest expertise, attempt to end it inside three days.

I like serving every slice, usually paired with chamomile tea for an added contact of leisure. Whether or not loved as a light-weight snack throughout afternoon tea or as an indulgent dessert, it’s all the time completely satisfying.
