Oatmeal raisin cookie baked oatmeal.

I’m one of those oddballs who loves oatmeal raisin cookies almost (almost!) more than chocolate chip, so I was head over heels for this. But if you’d prefer another cookie hiding in your oatmeal, this dish is fantastically customizable — for a chocolate chip oatmeal cookie version, up the vanilla to 2 tsp, omit the cinnamon, and swap out the raisins for chocolate chips. For a cranberry-orange one, add one to two tablespoons of orange zest, half a teaspoon of almond extract, and swap out the raisins for dried cranberries. It would also work wonderfully with a diced apple, or pear, or pretty much anything you can imagine short of ground beef. It’s kind of my dream breakfast.




  1. Preheat oven to 350 degrees.
  2. Optional: Following a genius tip from JC, below, you can toast your oats first. In a 10-inch cast-iron skillet, melt the butter over medium heat. Add the oats and stir to coat evenly, then continue to cook, stirring every few seconds to prevent burning, until oats smell toasty, like popcorn. This should take only 2-3 minutes, but gives the oatmeal a deeper flavor and makes it taste a little more cookie-like, in my opinion. But totally okay to skip it if you’re pressed for time! Otherwise, just mix together your oats, both sugars, ground cinnamon, baking powder, and salt in a 10-inch cast-iron skillet or 8×8-inch baking dish until well-combined. If using a baking dish, you may want to line it with parchment paper to prevent sticking.
  3. In a bowl, whisk together milk, vanilla, and eggs. You can also add a tablespoon or two of melted butter here, if you’d like. Pour the wet ingredients over the dry and give the dish a shake or stir it to evenly moisten. Scatter the raisins evenly across the mixture and stir again to incorporate.
  4. Bake for 30-35 minutes, or until golden on the edges. Oatmeal should still be soft in the center when removed but will set as it cools.


Everything in baked oatmeal is pretty loosey-goosey. You can increase or decrease the amount of milk to your preference — I have used up to 2 1/2 cups milk with good results, and have seen recipes that call for less. You can also use one egg instead of two or egg whites if you’re concerned about cholesterol. And, of course, you can feel free to up the sugar for a sweeter post-holiday treat — or decrease it if you’re already just that zen.
