This process assumes that you have already chosen your recipes and gone grocery shopping. You will want to use your longest available expanse of countertop for this. My assembly line turns two corners as it winds around my small kitchen, but that is fine.
You may need to make some adjustments depending on your individual recipes, but for most recipes, you can set up your assembly line like so:
Flour Line:
-Large mixing bowl
-Measuring cups and spoons
-Fork for stirring
-Flour
-Baking powder and baking soda
-Salt
-Cocoa powder
-Spices
-Any other dry ingredients that are added to the flour in your recipes
Butter Line
-Another large mixing bowl (or the bowl from your stand mixer)
-A second set of measuring cups and spoons
-Electric mixer
-Wooden spoon
-Rubber spatula
-Butter, shortening, margarine and/or cream cheese
-Sugar (white and brown)
-Eggs
-Vanilla and other extracts
-Chunks such as raisins, nuts, chocolate chips
-Rolled oats
-Any other ingredients that are added to the butter and eggs in your recipes
-Plastic wrap
-Felt-tip marker
To avoid transferring flavors from one recipe to another, you will start with basic recipes that have no spices, chocolate, or other strongly flavored ingredients. Starting with your first recipe, go down the line measuring out the amount of flour, baking powder/soda and salt into one bowl. Then, combine the butter, sugar, eggs, vanilla in your larger bowl as directed. Gradually stir the flour mixture into the butter mixture. After that, stir in any chunks.
Next, scrape down the edges of the mixing bowl so that it's fairly clean, shape the dough into a ball, and wrap it in plastic wrap. Identify the recipe by writing its name on the plastic wrap with a felt-tip marker, and refrigerate it. If it is a slice-and-bake refrigerator cookie, form it into a log instead of a ball, according to the directions in your recipe. If you plan to bake much later, you can even freeze the dough. Most cookie doughs freeze very well. Defrost at room temperature while still wrapped in plastic wrap, and unwrap only when dough is thoroughly defrosted. Otherwise condensation could add too much moisture to your dough.
When your first batch of dough is prepared, wrapped, and stored in the refrigerator or freezer, return to the beginning of your assembly line, without washing your dishes, and begin preparing the next batch of dough. When you have prepared all the recipes that contain no spices or cocoa, move on to the recipes that contain cocoa, and finally those that contain spices. This way, you will only have to do dishes once at the end of the process, and you will have several different kinds of dough waiting to be baked.
When all your dough is prepared, then you can finally put away all your ingredients, clean up the kitchen, and do your dishes. Now if you plan to finish your baking today, you'll have lots of space for rolling out your dough or setting out your cooling racks. If you plan to bake another day, you're done!
