My advice to anyone is start with pancakes. Make a few different recipes and pay attention to the differences. Then make them without a recipe. Switch up ingredients, sub in whatever you feel like, play with ratios. Once you have a handle on that, move to sourdough, cookies, or piecrust. Then do muffins. Leave cakes for last, because they are the most finicky. You’ll be baking with confidence and without a recipe in no time.
