Can I use a vanilla cake and convert part of it into carrot?
id guess not without some serious thinking, i dont think you can just add a carrot, youd want to add brown sugar and spices too.
SURE YOU CAN!!
My favorite carrot cake recipe starts with a french vanilla BC box mix. I get rave reviews every time.
PM me and I will give you my super secret recipe and tips .
edited to add : I think that if you add your own spices rather than using a spice mix or carrot cake mix, it tastes fresher and cleaner. The spices are kinda muddled and the flavor isnt as as good.
My favorite carrot cake recipe uses a boxed yellow cake mix to start, and it is AWESOME! I got the recipe on this website, as well.
