Oatmeal Cookie Baked Oatmeal

I get a lot of recipe requests and ideas from readers and, although I can’t try them all, I absolutely love hearing them. They’re so inspirational! Not too long ago, Sarah dropped me a line on Facebook asking if I had ever thought about making an oatmeal cookie flavored baked oatmeal. Well, what could be more natural than Oatmeal Cookie Baked Oatmeal?

But then I started to think, “what makes an oatmeal cookie taste like an oatmeal cookie?” What could I add to my generic baked oatmeal recipe to make it less like regular oatmeal and more like an oatmeal cookie? Of course it will need a little extra sugar, but I still want my baked oatmeal to be breakfast worthy and not just a large casserole dish full of dessert. So, I used a little extra brown sugar, increased the vanilla and cinnamon, added a pinch of nutmeg, threw in some raisins (obvi), and used up some unsweetened apple sauce that I had left over in my fridge (for added sweetness). Oh yeah! And butter. We’re going for “cookie” here, so I added a lil butter. The result? It’s like an oatmeal cookie’s older, more healthful sibling. Not quite as rich and sweet as an oatmeal cookie (otherwise it would just be one), but it shares the same genes for sure. And yeah, this Oatmeal Cookie Baked Oatmeal WILL make your house smell like oatmeal cookies while baking!

Oh, and one more note because this tends to be a source of confusion on all past baked oatmeal recipes: the texture of baked oatmeal is not crunchy. It’s soft and moist, yet solid. Kind of like a bread pudding made with oats instead of bread. :)

Baked Oatmeal Wet Ingredients

Preheat the oven to 375 degrees. In a large bowl, whisk together 1.5 cups unsweetened applesauce, 1 large egg, 1/2 cup brown sugar, 1/2 Tbsp vanilla extract, 1/2 Tbsp cinnamon, 1/4 tsp nutmeg, 3/4 tsp salt, 1 tsp baking powder, and 2 Tbsp melted butter.

Baked Oatmeal Wet Ingredients Whisked

Whisk those ingredients together until smooth.

Add Milk to Baked Oatmeal

Then add 1.5 cups milk and whisk again. It’s easier to add the milk after the thicker ingredients are already combined because it will be really splashy if you try to add the milk first.

Add Oats and Raisins

Add 1/2 cup raisins and 3 cups of dry old-fashioned rolled oats. I like old-fashioned rolled oats the best because the pieces are large and have a lot of texture. If you use quick oats, there will be less texture variation in your final product. 

Stirred Baked Oatmeal Mix

Switch from a whisk to a spoon and stir the oats and raisins into the wet ingredients.

Baked Oatmeal ready to bake

Lightly coat the inside of a 2-3 quart casserole dish (about 9×9 inches if using a square) with non-stick spray. Pour the oat mixture into the dish.

Bake the oats uncovered in the fully preheated oven for 45 minutes. The oats will absorb the liquid and become tender, but slightly chewy. The outer edges and surface should be ever so slightly browned.

Baked oatmeal tastes just as good cold as it does warm. Sometimes I reheat it in the microwave in the morning, but sometimes I just eat it cold. I love it with some cold milk poured over top.
