Purple Yam Cake
I have always been fascinated by the purple yams. I love their intense taste and their strong flavour.
Ingredients
For the Cake:
- 2 cups all purpose flour
- 1/2 cup corn starch
- 3 tsp baking powder
- 1 tsp salt
- 1 cup cooked purple yam boiled & peeled
- 3/4 cup whole milk
- 1 cup white organic sugar
- 6 egg yolks
- 6 egg whites
- 1/2 cup vegetable oil
- 1 tsp cream of tartar
- 1 tsp vanilla essence
- red and blue food colouring optional
For the Icing:
- 1 cup coconut cream
- 2 cups icing sugar
- 1/2 cup Philadelphia cream cheese
- 1/2 cup butter at room temperature
- 1 cup unsweetened desiccated coconut
Instructions
- Preheat oven to 325ºF. Combine together flour, corn starch, baking powder and salt and set aside.
- Blend together the boiled purple yam with coconut milk, sugar, vanilla essence, egg yolks and oil. Add the flour mixture little by little and whisk well gently until smooth.
- In a standing mixer beat egg whites with cream of tartar until foamy add food colouring and whisk until soft peaks form and the colouring is evenly mixed.
- Fold the egg whites gently into the cake mixture. Then I immediately poured the batter into a 8" round pan and the rest into a muffin tin lined with paper cups for the Ube cup cakes.You could use two cake tins and bake in the desired shape and size you want.
- Bake for 30 - 35 minutes. Mine took 30 minutes exact. Cool on wire wrack.
For the icing cream together butter, cream cheese and sugar then add the coconut milk and whisk well until smooth and spreadable.
- When the cake is cool enough, cut it into two layers and spread the icing in the centre and the top, then sprinkle the unsweetened desiccated coconut. Let it rest for an hour, then enjoy.
Notes
1. If you have cake flour then just use 2 1/2 cups of cake flour. You add corn starch only if you are using the All purpose flour.
2. It is your choice whether to add the food colouring or not. The second picture shows the cake slice without food colouring added. it is the natural purple yam colour.
3. You could also use the Instant pot to boil the purple yams. Add 1 cup of water to the Instant pot place yams on the stand which should be inside the IP then set the steam mode to 5 minutes.
4. Do not over bake the cake.
