I'm not one to rush the seasons, but this year I'm making an exception. 2020 just feels like the year to do it. Who cares if it's still hot and humid outside?? Let's crack open a can of pumpkin puree and get started on all those pumpkin recipes we try and cram into the fall time.

The first pumpkin recipe I've made this year is pumpkin baked oatmeal. It's a riff on my healthy baked oatmeal bars, which continue to be a household favorite for a filling and better-for-you breakfast.

With just a few ingredient swaps, this version, featuring pumpkin puree and lots of cozy spice, will have you all ready for fall.

Reasons to Love This Recipe

Oats are a beneficial addition to a healthy diet, featuring fiber and a host of other nutrients.
This is a one bowl recipe, minimizing the number of dishes that need to be washed.
The texture is great! It's not too mushy or too chewy, as the oats soften just right with this amount of liquid and the length of the bake time. And a spoon is not required as you can even pick up a bar and eat it on the go.

Recipe Ingredients

Old-fashioned oats: Also called rolled oats, old-fashioned oats are hardier than quick or instant oats and hold up well to the liquid content and bake time without becoming mushy. They soften perfectly without any overnight soaking or lead time.
Pumpkin: Real deal pumpkin is used here in the form of pumpkin puree. One whole cup (not can!) is responsible for the seasonably-appropriate orange hue and flavor.
Maple syrup: This provides natural sweetness, moisture, and a nice hint of complementary flavor. Honey can be used in a 1:1 substitution if you prefer.
Coconut/brown sugar: When I make baked oatmeal with bananas or applesauce I find they don't need any extra sweetness besides maple syrup, but with pumpkin? I tested out a few versions and think pumpkin's almost savory nature needs a bit more sugar. Just one-quarter cup of coconut or brown sugar takes the savory edge off without tipping it over into too sweet territory.
Milk: Any variety will do. I usually use 2%, though I've used oat milk no problem (non-dairy milk would make this recipe dairy-free).
Spices: Cinnamon makes up the bulk of the spices, with ground ginger, nutmeg, allspice, and cloves rounding out the mix. If it's more convenient you can use a pre-made pumpkin pie spice blend in place of everything but the cinnamon, still adding the cinnamon separately for a nice and warm flavor.
Nuts: Pecans and/or walnuts are favorites of mine in pumpkin baked oatmeal (and Bisquick pumpkin bread), but you can also leave them out.
Fruit: Dried fruit such as raisins or craisins are great, but you can also use something like fresh small-dice apple pieces.

Step-by-Step Instructions

Add the wet ingredients to a large mixing bowl: milk, pumpkin, maple syrup, eggs, and vanilla extract.
Whisk everything well until combined and smooth. I do this by hand -- an electric mixer isn't necessary for this recipe.

Wet ingredients whisked together smoothly in the mixing bowl.

Next add all of the dry ingredients (except the oats, nuts, and dried fruit) to the bowl: coconut or brown sugar, baking powder, cinnamon, ginger, nutmeg, allspice, cloves, and salt.
Give everything a good whisk to disperse everything evenly. It's especially important to make sure the baking powder is evenly distributed and not clumped together.

Baking powder and spices added to the mixing bowl.

Baking powder and spices whisked into the pumpkin mixture.

Pour in the oats and any nuts and dried fruit you're using.
Stir to moisten the oats well and mix in the nuts/dried fruit, making sweeping passes along the bottom of the bowl to really make sure the oats and liquid are combined evenly.

Now prepare the pan. Line an 8" x 8" square baking dish with a sheet of parchment paper, then give the parchment paper a quick spritz of cooking spray. Leave enough overhang along two opposite ends of the pan so you can more easily grab and lift out the pumpkin baked oatmeal for slicing once it's done. Pour the oatmeal mixture into the prepared pan and smooth out the top so it's in an even layer.

All that's left is to bake it. Bake in a 350°F/177°C oven for about 45 minutes, or until the edges have browned and the center has set. While it may be tempting to dive right in, resist the urge and let the slab of oatmeal cool completely before slicing, serving, and storing. This helps it hold together better and be less crumbly.

Storage Instructions

You can keep these bars stored at room temperature for several days without issue, but I prefer to refrigerate them as they're fairly moist. Just be sure that they cool completely before sealing in an air-tight container so condensation doesn't get stuck in there with them. A quick spin (thirty seconds or so) in the microwave to take the chill off is all you need and breakfast is ready.

Freezer: This pumpkin baked oatmeal also freezes very well! Wrap your bars in foil and place them in an air-tight container or bag. Then either transfer the bars to the refrigerator to thaw overnight, or simply give them a bit longer in the microwave in the morning and they're as good as freshly-baked.

Recipe Notes

Be sure to use pumpkin puree here, and not pumpkin pie filling. They're both canned and will likely be next to one another on the store shelves. Canned pumpkin pie filling is already spiced and sweetened.
While the coconut (or brown) sugar isn't 100% necessary (I've tested this oatmeal without), I found it added a welcome sweetness boost to the maple syrup as pumpkin puree isn't sweet at all. If you don't think you'd need extra sweetness you can leave it out without issue.
That said, drizzling maple syrup over top for serving is another way to bump it up if needed if you'd prefer to omit the coconut/brown sugar.

While this is a great fall breakfast, are you looking for something a little more festive? Baked eggnog oatmeal is one of my favorite ways to use up leftover eggnog. The flavor shines through!
