I run a very small teahouse and offer a few home-baked goods to accompany the tea. The kitchen is tiny and I can only bake a few items at a time, and I don't sell very much. Nevertheless, my customers like the fact that the items are fresh and home-baked, and it's important to me to continue to offer the stuff, and to have a variety of choices available. Problem has been that I spend several hours baking each day even though it's only a very small percentage of my revenue. The solution has been to find recipes where I can prepare dough/batter a couple of times a week, and then pop in the oven as needed. It works great for chocolate chip cookies and madeleines, and I'd like to expand into muffins and cupcakes. I've read the threads and it seems like some people believe batter can last a few days, while others prefer to bake and then freeze. I would prefer not to bake and freeze. So, I'm seeking your expertise, please. I imagine that the issue is leavening (maybe there are other issues like mixing method, I don't know), and that the use of double acting baking powder should help, but does anyone have guidance on great base recipes for muffins and/or cupcakes that will last as batter in the fridge for a few days and bake up great. Thank you so much!
