Frequently asked questions

Why are my cookies falling apart?

One reason your cookies may be falling apart is that they are too dry. You may have added too much flour.

They may also be crumbly if you use margarine instead of real butter. Also, cookies that are not done all the way or cooled properly will fall apart when you move them.

Why do you put a crosshatch pattern on these cookies? 

The early ones did not have the criss-cross pattern. In fact, the earliest ones were rolled thin and cut into certain shapes.

However, the criss-cross marks made with fork tines were first published in the Schenectady Gazette newspaper in 1932.

It was a way to make sure they cook evenly because they are so thick.

How do I make the best cookie consistency?

The trick to making your cookies chewy or crunchy depends on the amount and temperature of the ingredients.

For a crunchy consistency, you have to have the right amount of fat and dry ingredients.

Use shortening instead of butter and granulated sugar instead of brown sugar. 

For a soft and chewy cookie, you need more moisture and less dry ingredients.

You can substitute butter instead of shortening, use brown sugar instead of granulated, and cook it at a lower temperature for a longer time. 

How to store leftovers:

  1. Store: Leftover cookies should be stored in an airtight container or storage bag. In the refrigerator, they will stay fresh for a week. Or you can keep them on the counter in a cookie jar for several days.
  2. Freeze: If you made way too many, wrap them in plastic wrap or aluminum foil and store them in your freezer in a freezer bag. These will stay fresh for about three months. 
  3. Thaw: Remember to thaw these overnight before you plan to serve them for best results. Serve at room temperature.

Recipe tips:

  • Do not use an electric mixer for this recipe. 
  • Use parchment paper on your cookie sheet for best results. 
  • Dip the fork into sugar each time you use it to make the fork tine pattern so it will not stick.
  • Add an extra egg if you like them cakier.
  • Instead of trying to fork-tine these, just use your thumb to press them down.
  • Be sure to whisk your egg first so the yolk and whites are evenly combined into the dough. 
  • If you are using unsalted natural peanut butter, be sure to add a pinch of salt. 
  • Use a large bowl instead of a medium for a large recipe.
