Hi! I've been a lurker for a while and this is my first post. I want to make a marble pound cake for my parents on valentine's day. I don't do a lot of baking, so I research a bit on the recipe. I get the marbling part of it, but what confused me was the baking time. One recipe said to do 40 mins while another says an hour and a half. What is with the difference? Any other tips you can provide will be much appreciated.
