Well, I'm not sure how much I can help you with cleaning and shopping, but I might be able to make baking a bit less tedious.
Every so often, you will find these plastic drawer units on sales at a few of your local stores. I picked one up a few years back (at Canadian Tire for $29!) and it graces my kitchen for the month of December. How is this going to help you keep up with your baking?
This is how...
If you can get your head around it, you can make a batch of dough while you are getting dinner ready and bake it off as you clean the dinner dishes....after all, this is about trying to make this less stressful so get a batch in here and there would be optimal (the last thing you want to do is spend a whole Sunday baking when you have a million other things to do). Because you want to keep these biscotti dry in order to keep them crisp, you can simply store them in these drawers and they will keep for weeks. Look for this recipe later on today in the cooking tab.
Now, cover the drawer unit with a tablecloth and nobody will ever guess what is underneath it! And, whenever you have guests, or are running out to make a visit, you can remove the tablecloth, take out a tray and fill it with a beautiful assortment of goodies.
Now, if you can just find someone to clean your toilets and scrub down your kitchen, we will all be happy campers!!
