My favorite baking web site has to be Joy of Baking. This website is so good, it is like having a free cook book that keeps growing and growing. And it's not just recipes on their own, there are also videos if you are not sure about anything, like this one:
The recipes are divided into categories: types of food like cookies and muffins and ingredients like apple or chocolate. I like lemon cakes best! All the recipes I have tried from here so far work. What are my favourites? I'll give you my top three and then go try yourself!
1. Black forest cake. I always thought this one was very scary to try, but here it is explained very well.
2. Red velvet cupcakes. These are a big favorite in our family.
3. Sugar cookies. For when you need something super quick with few ingredients. Also good for decorating.
