If I had a signature cookie, it would probably be these Iced Oatmeal Cookies. The coffee-flavored glaze makes these cookies fly out of the cookie jar. Everybody seems to love cookies with frosting on top–or is it just me?!
In addition to Thumbprints, these cookies are my husband’s favorite. Since I only do thumbprints at Christmas, he requests and gets these oatmeal cookies more often than any other. Who needs more appreciation than your spouse?
What you can expect:
These thin oatmeal cookies will rise up in the oven. But don’t be surprised when they fall in a dramatic fashion soon after they are removed from the oven. No worries! That’s expected and normal.
Straight out of the oven, these cookies are crispy. Nevertheless, they will soften a bit the longer they sit around.

Ingredients and Substitutions:
- BUTTER: No substitutes. Unsalted butter gives the best flavor and texture. If you only have salted butter, cut the salt in half.
- SUGAR: Granulated sugar–I haven’t tried light brown sugar.
- EGGS: The recipe is written for large eggs
- HONEY: Honey gives the perfect chewy texture to these cookies. Maple syrup is a possible substitute but may change the flavor slightly.
- FLOUR: All-purpose flour is best–bleached or unbleached is fine.
- CINNAMON: Allspice is a good substitute if you don’t have cinnamon.
- BAKING SODA: No substitutes here. Baking powder is not the same.
- QUICK OATS: It’s important to use quick oats for just the right chewy texture. If preferred, use a food processor to chop old-fashioned oats to mimic the size quick oats.
- BLACK COFFEE (for the icing): Instant espresso is a good substitute. If you don’t want to use coffee, use milk.
Variations:
Ice these oatmeal cookies with coffee-flavored icing (part of the recipe) or try browned-butter icing.
For variety, try adding raisins or dried cranberries, about 3/4 cup.

FAQ about these glazed oatmeal cookies:
Using a small ice cream scoop will give you pretty, uniform cookies. Be sure to leave plenty of room on the cookie sheet. Typically, these cookies SPREAD! 
Yes. Store in an airtight container. Double wrap for best results. Best if eaten within 1-2 months.
Since these cookies are iced, let the icing dry before packing them. Use wax paper, parchment, or plastic wrap between the layers.

Parting thoughts: If you like cookie recipes with cereal in them, I suggest you check out these Chocolate Icebox Cookies with Chocolate Chips and these Raisin Bran Crunch Cereal Cookies. Although I wouldn’t call oatmeal cookies particularly healthy, they make a much tastier breakfast than a bowl of sticky oatmeal. (For some reason, I never convinced my mom that this was a good idea.)
