FAQs
Can I use regular milk instead of eggnog?
Yes, you can substitute eggnog with regular milk, but the distinctive rich and spiced flavor will be milder. Adding a pinch of cinnamon and nutmeg to the batter can help replicate that cozy taste.
Is it okay to leave out the rum extract?
Absolutely. The rum extract is optional and adds a traditional holiday note, but the cake will still taste delicious without it.
