General Questions
Q: Can I bake this in advance?
A: Yes! You can keep the layers wrapped for up to two days at room temperature or for up to one month layered in the freezer.
Q: Why do the flavours change? Why are the flavours better the next day?
A: The flavours of the blueberry and the frosting meld, and some of the sharper flavours are lost. The frosting mellows and the flavours deepen.
Q: What do I do if my ganache is too thick?
A: Gently reheating it using the double boiler method, or adding a teaspoon of warm cream and stirring will do the trick.
Q: Is food colouring necessary?
A: You will only need it if the purée is not bright enough. In this case, a natural colouring is preferable for a lavender tone.
Q: Is it possible to make this recipe dairy free?
A: Yes! Just replace the ganache with coconut cream, and use dairy free cream cheese and dairy free butter.
Q: How can I get a perfectly smooth slice?
A: Put the cake in the freezer until it is completely frozen.
