I have dozens of recipes for oatmeal cookies and recently had a craving for them.

Rather than making a whole batch of cookies that I would no doubt eat within a few days, I exercised some self-control and made one extra-large cookie. It’s the oatmeal counterpart to this XL Chocolate Chip Cookie.

My craving was handled on the spot and I didn’t have another 18 cookies starting back at me on the counter.  Win-win.

MY OTHER RECIPES

Other wins about this recipe include that it’s made in one bowl and without a mixer.

With all cookie baking I recommend chilling the dough because the finished product will bake up thicker and be less prone to spreading from a little chill time, even if it’s just a flash-chill in the freezer for 30 minutes. I tried baking this cookie without chilling the dough and the results was no where near as thick.

This jumbo cookie is wonderfully soft but the oats give it chewiness. Make sure to use old-fashioned whole-rolled oats. Quick-cook oats act more like flour and will not work here.

And of course there is chocolate galore. Not sure if this is a splurge cookie for one or a be-nice-and-share-some kind of cookie for two but it weighed about a half pound and my hand could’t even fit around it. Not complaining.

Ingredients:

  • 1 egg yolk from a large egg (discard white or save for another use)
  • 2 tablespoons unsalted butter, very soft
  • 2 tablespoons granulated sugar
  • 2 tablespoons light brown sugar, packed
  • 1/2 teaspoon vanilla extract
  • 1/3 cup old-fashioned whole-rolled oats (do not use instant or quick-cook oats)
  • 1/3 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon cornstarch
  • 1/4 teaspoon kosher salt, or to taste
  • 1/3 cup semi-sweet chocolate chips, plus more for adding on top before and after baking if desired (recommended)

Directions:

  1. To a large bowl, add the egg, butter, sugars, vanilla, and mix with a spoon aggressively for about 90 seconds, or until smooth and slightly fluffed, i.e. your bicep and shoulder should be burning if you’ve mixed well enough.
  2. Add the oats, flour, baking soda, cornstarch (keeps cookie extra soft), salt, and stir to combine.
  3. Add the chocolate chips and stir to combine.
  4. Roll dough in your hands to create a ball and then flatten about halfway or so that the mound is about 1 1/2 inches thick. I recommend chilling the dough, wrapped in plastic wrap, in the fridge for at least 2 hours to ensure the cookie stays thicker cookie and spreads less. If desired, add additional chocolate chips to the top of cookie (recommended).
  5. Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray and place the cookie dough on it.
  6. Bake for about 12 to 15 minutes (shorter for softer cookies, longer for more well-done cookies), or until edges have set and top is just set, even if slightly undercooked, pale, and glossy in the center; don’t overbake. Cookie firms up it cools. Exact baking time will depend on how thick your dough mound is and how well-chilled it is going into the oven.
  7. Remove baking sheet from oven, top cookie with additional chocolate chips as desired (recommended), and allow cookie to cool on baking sheet until serving. Cookie is best warm and fresh.

  1. This is perfect for a craving and would surely hit the spot! Love the addition of oats for texture :)

  2. Mmmm yes I want this! With a scoop of ice cream, and so much better than 18 cookies sitting on counter!!

  3. hey girl- yummy for my tummy!

  4. Would anybody know the measurements if I wanted to make a dozen of these?

    • You would multiply everything by 12 but honestly if you want 12 cookies, check the Related Recipes below this recipe in the post. There are literally 10+ other oatmeal chocolate chip cookie recipe to choose from that make approx 12-18 cookies each, depending on the exact recipe.
