Spread the batter onto 2 large jellyroll pans that are lined with Silpat
or parchment paper (I have tested both liners and both work). Spread it as thin as you can - this is really important so that they cook even and don't come out soft/chewy. Pay attention to the middle making sure there isn't too much there - push the batter all the way to the edges. It spreads easily with a spatula. Sometimes if my bananas are on the bigger side and I have too much batter I will get a third sheet out - you just want to make the batter on the sheets thin. You can see the thickness in the crackers on my images in this post.
