New Favorite Breakfast Alert!

I’m slightly obsessed with these scrumptious Banana Nut Baked Oatmeal Cups. I’ve made them a number of times in the last few weeks, and they have definitely become my latest go-to breakfast obsession.

Baked Oatmeal recipe

We happen to be pretty fond of baked oatmeal around here. Maybe it’s the fact that we live in the frozen tundra for 7 months out of the year, but a hearty, warm breakfast is right up our alley.

You’ll find any number of baked oatmeal recipes on our site, ranging from baked steel cut oats like this Baked Steel Cut Oatmeal with Apples and Cinnamon to regular rolled oats in this Blueberry Baked Oatmeal, but this is our only oatmeal CUP recipe. What makes it different?

It’s made in a muffin pan!

Not only do these Banana Nut Baked Oatmeal Cups offer portion control (which is exactly what we need around here after our excessive holiday eating habits), but they can be made in advance and popped in the freezer to pull out whenever you need a quick and filling breakfast.

Tips for making baked oatmeal cups

Making oatmeal cups is not rocket science, but there are a nuggets of information that you might find helpful if you’re an oatmeal cup newbie:

  • Grease your muffin tins well so the oatmeal cups don’t stick to the sides when you try to remove them. Running a knife around the edge of the tin is usually all you need to do to remove them cleanly.
  • A stainless steel scoop is a huge help in evenly dividing the batter between muffin tins. (If you’ve ever made a mess with transferring soupy batter from one container to another, you know what I mean.) I have several sizes of these scoops for various uses, but this one is perfect for muffins, cupcakes and oatmeal cups.
  • Prefer to use a plant-based milk? Go for it. You can substitute that seamlessly.

Note: Although this recipe is made in a muffin pan and the cups look like muffins when they come out of the pan, they are NOT muffins. Don’t be swayed by appearances; this recipe makes oatmeal cups that are far too soft to eat out of hand.

How to store baked oatmeal cups

Thought it’s tempting to dive into those fresh from the oven oatmeal cups because they smell so darn good, I do suggest waiting for them to cool slightly if you’re planning to eat them immediately or else they will be too soft to easily remove from the pan.

If you have the time, I prefer to thoroughly cool them before taking them out of the tins.

Planning to eat them this week? Place them in a sealed container and pop them in the fridge.

If you’d rather freeze them for later, I usually place the cups on a baking sheet lined with parchment and freeze them solid before putting them in a zip top bag in the freezer for up to 3 months.

Tip: Making a double batch of the recipe is just as easy as making a single batch (provided you have two muffin pans). I highly recommend this as they will go quickly!

A quick spin in the microwave is all it takes to ensure these Banana Nut Oatmeal Cups taste as fresh as if they just came from the straight from the oven.

The length of time in the microwave will depend on whether the cups are coming from the fridge or freezer. But if the cups are frozen, I usually defrost them at 50% power first before heating them through.

Which brings me to the best part of this recipe: My favorite toppings for Banana Nut Baked Oatmeal Cups

I know some people like to eat their oatmeal cups like a muffin but that’s missing out on all the yummy toppings!

Nine times out of ten I put my oatmeal cup in a small bowl and pour a little milk over the top before I reheat it. Then I add a healthy dollop of almond butter and a drizzle of maple syrup before stirring it all together.

So, so, so good!!

What I used to make these Baked Oatmeal Cups

  • You know we love the pans from USA Pans, and their muffin pan is no exception. I’ve never had sticking issues with this sturdy, easy-to-clean pan.  
  • Make quick work of dividing the batter among the muffin cups with a stainless steel scoop. This size is perfect for any muffin recipe.   
  • I always sprinkle a bit of this sugar on top of my oatmeal cups. The sugar caramelizes slightly and adds a delicious crunchy bite. Not necessary, of course, but oh so tasty!

    Hello, This is a recipe I definitely will be making frequently. Just two questions – 1) when is the brown sugar added (11th line/item), and 2) what happens to the oats (12th line)? Thank you! 🙂

      Hi! Oops, I left out the directions for the brown sugar. Recipe is amended now. Hope you enjoy it!

    This sounds delicious but I was just wondering how many calories it has in it?

    There was too much liquid for the amount of oats, I had to cook this for much longer and they are still too moist in the center for my liking although edible. I baked for 15 mins longer to get them to brown. Definitely bake this with less milk! They do taste very good and I chose this recipe over others because there is little oil/butter and sugar, making it a much healthier choice. Thanks!

      I’m glad you found a way to enjoy them. I make them a few times a month and never have an issue with the liquid to oat ratio.

    I also found there to be WAY too much milk. Takes much much longer to cook than 20 minutes. Maybe 15 minutes or so more? Is there a revision to the recipe that I don’t know about? I added extra oats, too, to soak up the milk. It made about 17. Did I do something wrong?

      Hi Sandra, these oatmeal cups will not be hard like muffins. They will still be soft when you take them out of the oven. But once they cool, they are easy to reheat into an oatmeal-like consistency when you’re ready to eat them. Hope that helps!

        Oh…I baked them for longer so they are like muffins. I’ll try your way ne t time. Thanks.
