This easy recipe for Magic Eggnog Custard Cake takes one mix and makes a cake with three different layers – perfect for Christmas or other holiday celebrations and absolutely delicious!
Preheat your oven to 325 degrees. Line an 8x8" baking dish with parchment paper (or use a silicone baking dish and give it a light spray with cooking spray).
Mix together yolks, sugar, butter, cinnamon, and vanilla. Slowly mix in flour until there are no lumps. Slowly add eggnog (this will make batter thin).
Bake for 60 minutes at 325 degrees, until top turns brown and cake is set. Allow to cool for 30 minutes before dusting with powdered sugar, cutting with a sharp knife, and serving warm.
