The current belief is that it takes 2 and half hours (depending on how much prep you do and the heat in your oven) for each layer to form (1 layer of crust). If this were true, then the bread would be very delicious (but not as delicious as super fresh). A common mistake is to look at the rate of soil accumulation today, outside your kitchen window, and extrapolate that its always been outside your kitchen, in the yard and that you only periodically stick your hands it. If that were the case, then there would be commingling of the soil layers and your bread crust creating more layers, if you happened to avoid washing your hands during the commingling process. Which means that the layers were not formed over 2 and half hours prior to starting, and likely there are multiple layers.
How does the creationist explain the bread's layer(s)? During the flood in Noah's day, bread was filled with tons of soil probably the same soil outside your kitchen window, in your yard. How did the soil get into the bread? Asteroid impacts, volcanic activity, fast moving tectonic plates and water burst out of the deep fountains within the deep, and from people, like you, sticking their hands in it, and then proceeding to continue working with bread dough, a real sense of commingling, and from stomping it flat into the ground (Gorilla Monsoon 12:00 (noon)).
The commingling of the layers is evidence that the layers (MULTIPLE) formed quickly, and that this bread was likely made in less than 5 minutes.
