Why are my Christmas Kitchen Sink Cookies really flat?

Be sure your butter is soft but not at all melted. Any melting can cause the dough to be softer and the cookies to spread more. When flattening the cookies, flatten them only slightly.

How to Store Kitchen Sink Christmas Cookies

To keep your Kitchen Sink Christmas Cookies fresh and delicious, proper storage is essential. Here's how to store them.

Room Temperature

Store your cookies in a container with a tight-fitting lid or a resealable plastic bag works well. If you're stacking the cookies, place a sheet of parchment paper or wax paper between the layers. Your cookies will keep up to 4 days.

Freezer

Transfer any leftover cookies to an airtight container or a freezer-safe resealable plastic bag. Squeeze out any excess air from the bag to prevent freezer burn. Store for up to 3 months. Thaw at room temperature for about 20 to 30 minutes before serving.

Frequently Asked Questions

Be sure you’re using a large egg and your butter is soft (it leaves an imprint when touched). Be sure to bake them for the minimum time. Check to see that they are light brown, if not, bake them a minute or two longer. Did you know that leaving your baked cookies on the hot cookie sheets continues to cook them? Be sure to move these cookies from the cookie sheet, 2 minutes after baking, to a cooling rack so they don’t get hard. They are best enjoyed within a day or two after baking them.
