I want to bake a cake with 3 layers, but I only have one baking pan and thus I will have to bake them one by one (already thought about making one big cake and dividing it into 3 parts but I pref not to use that method).
The problem is it takes 35 minutes to bake one layer and the batter contains baking soda and baking powder and I'm worried it will affect the outcome since I'm not baking the other 2 layers immediately after adding the baking soda.
So my question is, can I let the batter for the other 2 layers wait before adding to the oven?
Making the batter and separating into 3 and then adding the baking soda and powder isn't an option since I would have to mix it again which will affect the result. And I also don't want to make the batter for each layer separately.
