My husband wanted a really eggnog tasting cake so I experimented until I came up with this one. It is really good after being refridgerated a few hours. My kids love it with caramel sauce and fresh whipped cream with powdered sugar, cinnamon and nutmeg sprinkled on top.
Then Grease and flour a 9"x13" cake pan. (I use Baker's Joy spray)
Next mix the egg, oil, eggnog, cake mix, sour cream, rum extract, and apple pie spice in a mixing bowl for 2 minutes, scraping bowl as necessary.
Do not be tempted to add more rum flavoring. The extract is very strong.
Next pour the cake mix into prepared pan and bake in your oven at 350 for 29 - 32 minutes. I check around 29 minutes and the top of my oven is the hottest so I place the cake on the top rack.
Take out when cooled.
prepare whipped topping with apple pie spice, cinnamon or nutmeg and place on top. I also make a butter rum sauce but it is very strong. A caramel sauce would also go well with this cake.
