When you start decorating your cookies before they are completely 100% cool, the icing will melt. Make sure each batch is cooled before you begin to add the icing. Our Test Kitchen recommends decorating your cookies the day after you bake ’em.
Dip cookie dough rounds in sprinkles or sugar before baking. On ungreased cookie sheet, place cookie dough rounds about 2 inches apart. Bake 12 to 16 minutes or until golden brown.
Although I’ve tested them for longer and the batches I’ve tried seem fine for up to 4 weeks, my general rule of thumb is up to 2 weeks. I know they’re fine to eat at 4 weeks, but I feel better about giving the cookies away when the recipients don’t need to eat them right away.
Add sprinkles after baking
You can use frosting or an egg wash to get sprinkles to stick to baked cookies. Whichever method you use, start with cookies that have cooled completely. Top the cookies with frosting (homemade or purchased) that is soft but not too runny. (Sprinkles will not stick to dry, stiff frosting.)
Do you put sprinkles on brownies before or after baking?
Many desserts receive a sprinkling of “jimmies” after baking. However, unless the the baked goods are frosted, the sprinkles usually fall off. If you dust the top of brownie batter with sprinkles just before baking, the sprinkles slightly sink into the batter and remain in position after baking.
I always let them cool on the sheet for at least four hours, sometimes more before moving them into an airtight container. I prefer waiting until they are a day or two old before decorating them to reduce the chance of oil from the cookie leaching into the icing and causing icing spots.
Can sugar cookies be left out overnight? Yes. Sugar cookies can be stored in a cookie jar at room temperature for 2-3 days or in a cool, dry, airtight container for up to 3 weeks.
