I heard that this It's an awesome recipe for a stable enough Carrot cake for a wedding cake. But i can't find the recipe. Does anyone have it or know a dense Carrot cake recipe that doesn't have pineapple?

Try the smitten kitchen recipe... it's what I use. Don't worry that it shows cupcakes, I have been using this recipe to make layers cakes for the last 5 years.
