Using a thin or offset spatula, transfer the coins to a wire rack to cool completely, about 30 minutes. Once cooked, if they are not crispy, feel free to add them back a baking sheet and bake 1 minute or longer and cool on a wire rack one last time. Before reusing a baking sheet, remove any excess oil using a paper towel. However, leave a little shine behind.
Lace Look: If your crackers turn out looking like lace that usually means that your butter wasn’t soft enough and stayed in clumps instead of combining with the other ingredients. Once the heat of the oven hits those clumps of butter they melt away leaving holes in the crackers.
Some Are Brown: If some of your crackers turn too brown and crispy while others are not, you may have slice some thinner than others. Consistency in thickness is extremely important.
