Purple Sweet Potato Vintage Cake

Chiffon Cake recipe from https://www.youtube.com/watch?v=YLO7A--OehA&ab_channel=sheldo%27skitchen

Custard filling from https://preppykitchen.com/vanilla-custard/

Ermine buttercream from https://www.recipetineats.com/fluffy-vanilla-frosting/#wprm-recipe-container-50424

Modifications:

1. Added purple sweet potato powder to chiffon cake - did not taste it though

2. Fillings: custard + a little bit of whipped cream

3. Tried using heavy cream for the outside, but since it was previously frozen, it would not whipped properly. Used Ermine buttercream instead.

4. Gold pearls: chocolate pears covered in gold dust
