I’m just getting into baking and cake decorating. Where do I start?

Just start. Find recipes that excite you and start baking. I don’t think there is one good recipe for beginners. I think it’s more important to find a recipe that you’re excited to eat, and then make it! No matter what it looks like, you know you’re going to enjoy it and that’s the whole point. Then look for opportunities or excuses to bake- with each time you make a new cake, you learn something new and get a little better.
