If you don't care whether the recipes are healthy, go to
http://www.joyofbaking.com. It's very old school...I've never personally tried any of their recipes, but they come with complete instructions.
You can find a recipe for almost anything at
http://www.allrecipes.com. Plus, people review the recipes, so you get lots of handy tips!
For healthier substitutes of desserts and such, you have to check out the recipes at this site, and also at
http://www.calorieking.com.
If you want more, try Googling whatever you're making! There are a TON of recipe websites out there, both healthy and who-cares.
Have fun
