Easy, classic iced oatmeal cookies recipe, homemade with simple ingredients. Loaded with cinnamon and nutmeg. Perfect soft and chewy texture in the center with slightly crispy edges. Topped off with old fashioned crackly vanilla icing.

Christmas and even Thanksgiving won’t be complete until I bake a few batches of these cookies and share them with my family and friends along with my Classic Spritz Cookies and Classic Snickerdoodles Cookies. They are all even better than the store-bought cookies and require ingredients that you already have on hand.

The 2 key ingredients that truly enhance the softness of today’s cookies are brown sugar and molasses, which add so much moisture.

Oatmeal Cookie Icing

It’s a simple sugar cookie icing or sugar cookie glaze. There are no egg whites or meringue powder in this recipe. It’s made by mixing together powdered sugar, milk, vanilla extract until thick, smooth and creamy.

The consistency is very important. If the icing is too thin, it will drip off the cookies. It needs to be thick, smooth and creamy. If it’s super thick (almost glue-like), it may be clumpy and won’t stick to the cookies properly.

This icing dries hard at room temperature, just like royal icing, allowing cookies to be stackable. This will take a few hours and timing varies, based on humidity in your area.

Tips and Techniques

  • All ingredients must be at room temperature– Because they blend together smoothly and evenly.
  • You must chill the dough– This prevents over-spreading during baking and allows the cookies to hold their shape.
  • Don’t over mix cookie dough– Because that will yield very tough cookies. It’s okay if there are some lumps in the dough.
  • Make ahead instructions– You can make them 2-3 days in advance. They are also stackable and perfect for shipping during Christmas holidays.
  • How to store cookies? Can you freeze cookies?- Make cookie dough balls and freeze them up to 1 month. When you are ready to enjoy them, simply bake and ice them. Since they would be frozen, your baking time may be a few minutes longer. You can also freeze baked cookies without icing in a sealed container for up to 1 month. Just ice them when you are ready to enjoy them.
  • Adjust spices– This is based on your preference. I only used cinnamon and nutmeg but you can use a spice blend like pumpkin pie spice or a combination of other spices of your choice.
  • Use old fashioned rolled oats– Those are not the same as quick oats or instant oats and cannot be used interchangeably in this recipe.
  • Oats must be pulsed in a food processor- You cannot skip this step. because it helps create that chewy texture and compact cookie structure. Just pulse it a few times until the oats are rough and crumbly. DO NOT pulse them so much that they become oat flour.
  • Measure properly- Baking is science. Don’t eyeball anything. Use measuring cups and measuring spoons.
  • Use unsalted butter- Because that prevents these cookies from becoming too salty. Also, don’t replace butter with oil because that alters the texture dramatically.
  • How to get that perfect crackled icing appearance? The icing consistency is very important for this. It should be thick. Also, don’t dunk the entire cookie into the bowl of icing. Only lightly dip the top of the cookies and quickly tap off excess.
  • Don’t skip the icing– Because it really takes these cookies over the top, in terms of appearance and flavor.
  • Molasses substitute– This is obviously my first choice because it tastes the best and adds a wonderful subtle earthy Fall flavor. Maple syrup would be my second choice.
  • They taste the best next day- The icing has a chance to fully set, the spice flavors intensify and the texture is perfect- soft, chewy, firm!
  • Iced oatmeal raisin cookies– Stir in 3/4 cup raisins in the dough.
  • Make iced ice cream cookie sandwiches– Fill vanilla ice cream between 2 cookies to a more delicious treat.

Ingredients

  • 2 cups Old fashioned rolled oats Not quick oats
  • 2 cups All-purpose flour
  • 1 tsp Baking powder
  • 1 tsp Baking soda
  • 2 tsp Cinnamon powder
  • 1/2 tsp Nutmeg powder
  • 1 cup Butter Unsalted, Room temperature
  • 1 cup Brown sugar
  • 1/2 cup Granulated sugar
  • 2 Eggs Large, Room temperature
  • 1 tbsp Molasses
  • 2 tsp Vanilla extract
Icing
  • 2 cups Powdered sugar
  • 2-2.5 tbsp Milk Whole or 2%, Can also use heavy cream
  • 1/4 tsp Vanilla extract Use clear extract to prevent any discoloration

Instructions

  1. In a food processor, add oats and pulse a few times until you have a rough and crumbly mixture. It should NOT be a smooth oat flour!

  2. In a medium bowl, whisk together these rough oats, flour, baking powder, soda, cinnamon and nutmeg. Keep aside.

  3. In a large bowl, cream together butter, brown sugar, granulated sugar until light and fluffy.

  4. Add eggs, molasses, vanilla extract and mix until smooth.

  5. Gradually, add the flour and oat mixture and and mix until just combined. Don’t over-mix!

  6. Cover and chill dough in the fridge for at least 30-40 minutes to make it easier to handle.

  7. Scoop out small portions of the dough and roll into balls. 

  8. Place them on a cookie tray, lined with parchment paper. If you prefer flatter cookies, you can gently flatten the balls with palm of your hands.

  9. Bake at 350 degrees F for 10-12 minutes or until edges are light brown and firm but centers are still slightly soft. 

  10. Remove cookies from oven and let them cool in the trays to allow them to cook a bit further.

  11. While they are cooling, prepare the icing by mixing together powdered sugar, milk, vanilla extract in a small bowl until thick and smooth. You can add a little more milk, if you like but remember the icing cannot be runny but it can also not be super thick because then, it won’t stick to the tops of the cookies. 

  12. Now, dip only the tops of the cookies very lightly into the bowl of icing and let excess drip. Place iced cookies on a tray and let the icing set at room temperature so that cookies can easily be stacked later. This can take a few hours.

  13. Enjoy!

Recipe Notes

  • Read all my tips above.
  • Once the icing sets, cookies can be stored in a cookie jar at room temperature for up to 3 days. They can also be stored in a sealed container in the fridge for 3-4 days.
