Do I have to peel the carrots?
If your carrots are fresh and the skin looks smooth, you can skip peeling. If they are a little rough or dry, peel them. Either way, grate them finely so they melt into the cake.
Can I use pre-shredded carrots?
You can, but they are usually thicker and drier. If that is what you have, run them through a food processor a few pulses to get them finer, or expect a slightly less tender crumb.
Why is my cream cheese frosting runny?
Usually it comes down to temperature and texture: the cream cheese or butter was too warm, the brand of cream cheese is extra soft or watery, or the frosting got whipped long enough to warm up in the bowl. Fix it by chilling 20 to 30 minutes, then re-whipping briefly. If it is still loose, add 2 to 4 tablespoons more powdered sugar.
Can I make this as cupcakes?
Yes. Fill liners about 2/3 full and bake at 350°F for 18 to 22 minutes. You should get about 20 to 24 cupcakes, depending on how generously you fill the liners.
Can I bake this in a 9x13-inch pan?
Yes. Bake at 350°F for 35 to 45 minutes, until a toothpick comes out clean or with a few moist crumbs. Let it cool completely, then frost right in the pan for the lowest-drama finish.
Can I make it nut-free or pineapple-free?
Absolutely. Nuts are optional and so is pineapple. The base cake is still rich and flavorful without either.
Can I make the frosting ahead?
Yes. Make it 1 to 2 days ahead and refrigerate. Let it sit at room temp for 10 to 15 minutes, then re-whip briefly to bring it back to swoopy.
