Author Notes

This updated version takes the best of the classic and makes a few small-but-impactful tweaks, all while making the most of oats. Brown butter and molasses keep the cookies tender and chewy in the middle, but crisp and light on the edges. The marshmallow fluff adds sweetness and an airy texture, and the oat milk adds a very subtle flavor that complements the cookie. This recipe is very easy to customize to make your own. Nuts, chocolate chips, coconut, turmeric? All fair game. —Food52

What You'll Need
  • For the oatmeal cookies:
  • 1 cup unsalted butter
  • 2 cups all purpose flour
  • 2 cups quick oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 3/4 teaspoon cinnamon
  • 1/4 teaspoon ground clove
  • 1/4 teaspoon ground nutmeg, preferably fresh
  • 1 cup dark brown sugar, packed
  • 2 large eggs, room temperature
  • 1/4 cup dark molasses
  • 1 teaspoon vanilla extract
  • For the oat milk filling:
  • 1/2 cup unsalted butter, room temperature
  • 2 cups powdered sugar
  • 2 tablespoons Planet Oat Original Oat Milk
  • 1/2 cup marshmallow fluff
  • 1/2 teaspoon vanilla extract
  • 3/4 teaspoon kosher salt
  1. Make the oatmeal cookies: Place a rack in the middle of oven; and preheat to 375º F. Line 2 or 3 baking sheets with parchment paper.
  2. Cook butter in a small saucepan over medium heat, stirring often until it foams and then browns, about 6 to 8 minutes. Place the brown butter into a large mixing bowl and let cool for 10 minutes.
  3. Meanwhile, whisk together flour, oats, baking soda, salt, and all the spices in a separate medium bowl. Set aside.
  4. Add the brown sugar to the cooled brown butter. Using an electric mixer on medium speed, beat until fully incorporated, about 1 minute. Add molasses and mix until incorporated. Add eggs and vanilla, then mix again until fully combined.
  5. Add the dry flour mixture to the wet mixture and mix on low until just combined. Be careful to not over-mix.
  6. Using a 1-ounce ice cream scoop (about 2 tablespoons), scoop out dough onto lined baking sheets, spacing about 3 inches apart. Do not flatten the cookies. They will spread out in the oven.
  7. Bake for 7 to 8 minutes, or until the edges are golden-brown. Let cool on baking sheets for 10 minutes and then transfer to a wire rack to cool completely.
  8. While the oatmeal cookies cool, make the cream filling: Using an electric mixer on medium speed, cream together the butter, oat milk, and powdered sugar in a large bowl.
  9. Add the marshmallow fluff, vanilla, and salt. Mix until fully incorporated.
  10. Assemble the cream pies: Take 1 heaping teaspoon of filling and dollop it onto the center of one bottom-side-up cookie. Use the back of the spoon to evenly spread the filling to the edges. Use a right-side-up cookie to top it off.
  11. Chill the oatmeal cream pies for 15 minutes, then serve.

Made these this weekend--minus the filling. Not a fan. But the cookies were delicious. Yes the instructions were out of order, but I figured it out. I reduced the sugar by about 25% as we like them less sweet. A little crumbly due to reduced sugar, but that was ok. Excellent with milk--regular milk for us....

Definitely an incredible recipe. My only modification would be to half the butter, and double the marshmallow fluff in the frosting. At room temperature, the filling gets too liquid

Going to attempt to make these this weekend! I did just want to mention it looks like the recipe steps are out of order towards the end there.

Update: made these today and they are delicious. The brown butter and molasses really stand out in this recipe. Adding this to my regular rotation of baking recipes.

Were the steps out of order? If so, what steps did you follow? Thanks.

Yeah, steps 8-11 are mixed up somehow. I chilled the cookies after baking for 15 min (I think that's what the recipe calls for) and then made my frosting while they were cooling in the fridge. The frosting directions are messed up but I basically beat the butter, powdered sugar and oat milk together on med high for about 3 min. Then I added the vanilla, salt and marshmallow fluff and beat for another minute. Assembled the cookies after that. Hope this helps!

I'm sure an experienced baker could figure out how to bake and fill these, however, the instructions should be edited for novice bakers. Some of the steps are out of order and some are in there twice.
