Lightly sweetened whole-grain Baked Oatmeal Cups with banana and zucchini make the perfect healthy breakfast or afternoon snack on-the-go! So moist and delish with a smear of peanut butter.

When people tell me they forgot to eat breakfast, I get...confused. Like totally, completely, utterly bamboozled.
From my chocolate peanut butter oatmeal cups and apple oatmeal cups, we've got portable oatmeal options!
I love how they're pre-portioned so you can grab a couple for an easy peasy breakfast on-the-go. Healthy. Easy. Lasts all week. Freezer friendly. We can do this, yo!
The low down on key ingredients
- Old fashioned (rolled) oats: I developed this recipe to have a base of 100% whole grain oats. We don't want quick or instant oats here. Use certified gluten-free if needed.
- Bananas: Just like in my best ever gluten free banana bread, the riper the better since they're playing a major role in sweetening this. You'll want to make sure you have a cup, which is 3 small or 2-ish large bananas.
- Zucchini: You'll need one medium unpeeled zucchini, about 7oz, freshly grated. No need squeeze!
- Milk: Any kind of milk, dairy or non-dairy, will work in this recipe.
- Chia egg: To help bind the batter and add height. You can also use flax eggs or regular eggs. I found that chia worked better to bind them than flax.
- Almond butter: For flavor and fat in place of oil or butter. I've also tested these with peanut butter and they're great!
- Maple syrup: For a bit of extra sweetness--trust me, don't skip it! You can also use honey, or omit it for a no added sugar oatmeal cup. I tested these with honey and they were delish.

Let's customize!
Baked oatmeal is also splendid because you can totally do you.
- Make it chunky monkey style: Swap almond butter for peanut butter and add chocolate chips for a real morning treat.
- Amp up the protein: Use two eggs instead of the flax and add a couple scoops of your favorite protein powder or a couple tablespoons of hemp seeds to the batter.
- Feeling low-sugar: Leave out the maple syrup completely and use extra ripe bananas for natural sweetness.
- Make it an oatmeal bake: Trying to ditch the muffin tin? You can make this in a 9x13inch baking dish, too. It'll take longer, so keep an eye on it.

Expert tips for grating zucchini
That's right...we're slamming veggies for breakfast. Hallelujah.
- Don't squeeze out the liquid. This recipe calls for 1 ½ cups of zucchini and we are not squeezing the water out because we're actually relying on the natural moisture. A small zucchini will get you closer to a cup, so I recommend a medium one.
- Grate first, then measure. Since zucchini vary so much in size, definitely grate it and then measure out the correct amount after. I weighed it to add more clarity and it was about 7 ounces. Freeze any extra for smoothies!
- No need to peel. More fiber and nutrients, please. Just wash it and trim the ends. I like to use a box grater over a plate. Or maybe you're lucky and you have a box grater with an attachment that catches the goods at the bottom? Blessed.

How to store
You can store leftovers on the counter for up to 2 days but then you'll want to transfer to an air-tight container and store in the refrigerator for up to 1 week.
In order to reheat, simply warm in microwave for 10-15 seconds.
Freeze for later
Simply freeze them in an even layer on a baking sheet. Once frozen, transfer them to a freezer-safe baggie and freeze for up to 3 months.
You can transfer them to the refrigerator the night before so they're ready to go in the morning.
Pretty please let me know how this recipe turns out for you by leaving a star rating and/or comment! I hope you adore it as much as I do.

Description
Lightly sweetened whole-grain Baked Oatmeal Cups with banana and zucchini make the perfect healthy breakfast or afternoon snack on-the-go! So moist and delish with a smear of peanut butter.
Ingredients
- 1 tbsp chia seeds + 3 tbsp water (or sub 1 egg)
- ¼ cup almond butter
- ¼ cup pure maple syrup
- 1 cup mashed overripe banana (2 large or 3 medium bananas)
- 1 ½ cups grated zucchini (1 medium zucchini, about 7oz. Don't squeeze water out.)
- ½ cup unsweetened vanilla almond milk
- 1 tsp vanilla extract
- 3 cups old-fashioned oats (use certified gluten-free if necessary)
- 1 tbsp baking powder
- 1 tsp cinnamon
- ½ tsp fine sea salt
- Optional add-ins: ¼ cup chocolate chips and/or walnuts
Instructions
- Preheat oven to 375F. Spray a muffin tin (I used two, you can also pour the extra batter in a dish for an oatmeal bake) with cooking spray or line with silicone muffin liners.
- Place chia and water in small bowl. Stir and set aside to "gel." Place bananas in a large bowl and mash with a fork. Make sure they measure to be 1 cup. Add grated zucchini, almond milk, vanilla extract, almond butter, maple syrup, and chia mixture, stirring to combine.
- Add oats, baking powder, cinnamon, salt, and add-ins of choice. Stir until just combined. Spoon mixture into muffin cups, filling to the top. You will have leftover batter if only using one muffin tin.
- Bake for 23-28 minutes, or until a fork comes out clean. Cool on a wire rack. Store cooled oatmeal cups in an air-tight container in the refrigerator.

A friend gave me 2 yellow squashes ... I wonder if I could sub these for zucchini?

Hey there, I'm a huge fan of matcha and the zucchini look way awesome! Amazing banana zucchini oatmeal cups recipe! Thx Alexis!
Justin says
Any suggestions on how to freeze?
Alexis says
Just add a couple scoops, no prob!
Anne says
I made these but they came out raw in the middle. So sad. ? Must have had zucchini's that were too big.
Alexis says
Hey, Anne! Did you try baking them longer?? Simple fix!

Delicious. So it is easy to guarantee the domino lunch. Thanks for sharing.
Natalie says
Do you have the nutrition facts for the zucchini oat muffins somewhere? I’m sure I’m just not seeing it and it’s posted but can you let me know!
Annalise says
Ah, I agree! I am making these now and wondering... Does anyone have any comment?
Alexis says
You're so welcome!!
Lynne says
These look delicious! I'm trying to find things that don't require effort in the morning - sometimes even a bowl of oatmeal is too much effort for us non-morning people.
I also want to thank you for mentioning non-vegan options for us omnivores.
Kelsey says
Super excited to try these! Do you think t would turn out okay if I ground the oatmeal into oat flour to make a smoother muffin, would love to know your thoughts!

Alexis says
Hey Kelsey! Unfortunately I've never tried that so I can't vouch for the results :/ here's a couple delish smoother muffin if you're interested!
Julia Kruz says
Banana zucchini oatmeal cups is something new for me. I think I'll add the eggs to your recipe and I'll do it in the next weekend. It will be an excellent breakfast for the family:) Thanks for sharing!
nitasSmiling says
I made these last night and they are soooo good. Does anyone know what the caloric count is for one muffin?? I can't find the nutritional facts anywhere.
Paul Hayes says
These are such a great idea. I always have an overload of zucchinis every year. Now I can add this great recipe to the options.
Alexis says
Yes! I love all of the sneaky ways you can use zucchini 🙂
Jerilyn says
Hi, I am new to your site and these muffin cups look great. I was wondering if the baking powder is really necessary, as they seem to be solid little things that don't rise based on their natural firmness. I would really appreciate your thoughts about this, thanks.
Jerilyn says
Hi, thanks for your quick response. I made the recipe this afternoon and they turned out really well without the baking powder. I did use eggs and the oat cups actually puffed up a little bit in the centers. I used chocolate almond milk and a few chocolate chips and they are dense and deliciously hearty! Thank you. 🙂
Alexis says
I would definitely try it without! The consistency might be a bit difference but it'll definitely taste DELISH.
mtmc says
What a breakfast recipes. i just pined this on my board. Thanks from the foodies.
Alexis says
So yum. Thanks for the love!
Nicole Cuello La O says
What a great, healthy, easy, GF breakfast! I made mine with carrots, instead of zucchini, because that's what I had on hand and they worked out fabulously! I used 1/4 c. of maple syrup, but will add carob nibs or chocolate chips next time to add a little more sweetness. (Used eggs, 2% cow milk & cashew butter.) Hardest part was grating the carrots.
Elizabeth Sherer says
Hi! Love these muffins. Thanks for keeping me nourished!
Alexis says
Thanks so much for letting me know about this, Elizabeth. Very much appreciated!
Ashley says
These look great! I love that they're only sweetened with the bananas and there's no other sugar added. I think I have a few of your other recipes on my Pinterest too so I figured I'd come give you some comment love!
Julie says
Could you bake this in a larger pan to make a baked oatmeal instead of mini cups?
Thanks for writing & sharing 🙂
Alexis says
Sure! You'd have to increase the baking time, though.
Trisha says
These muffins are fabulous and so easy to make. I love this recipe and I have made it several times.
I have one question, should I be storing these in the refrigerator? I have been storing them in a tupperware container on the counter. I notice by day 4 they have peach fuzz growing on them. Thoughts?
Thanks again for this great recipe!!
Alexis says
Awesome! So thrilled you like them, Trisha! Yep--fridge is best. See step 7 🙂
Deryn @ Running on Real Food says
Well, these are just perfect! Breakfast next week, on repeat. Thanks!!
Jackie H says
We have nut allergies I our house. Do you have a recommended substitute for the peanut/almond butter?
Jordana says
I am also curious whether you can use real eggs, and if so, how many?
Alexis says
Hey there, just updated the recipe to reflect that you can use 2 regular eggs instead of the flax/chia and water combo. Hope that helps!
Jordana says
Thank you! That did help - I made these yesterday and they are DELICIOUS! My daughter (12 months) loved them too!
Aja says
2 eggs or 1? It’s written with one ?
Alexis says
One but two is fine 🙂
Anna says
I am SO glad. That I'm not the only one whose "crazy". I plan my world around food, too. There's others like me. It's comforting. Thank you for these wonderful recipes...I'm hungry now.
Anna says
I'm reading your blog from all-the-way-over-here Spain, and after visiting three different supermarkets I finally got the ingredients to make your recipe this morning. (Maple sirup, flaxseeds and almond butter requiered some extra work to find). Even though I totally missed adding the 1/2 cup of almond milk, the cups turned out to be really good and tasty. So thank you for sharing such a great treat, without flour or sugar. Muchas gracias, Anna
Alexis says
Yep!
Gale Holland says
Can you make oatmeal cups with regular milk and peanut butter I hate almond milk and almond butter
Jessica Jackson says
Hi! Just discovered this recipe and cannot WAIT to try! I was going to use your tip to incorporate a couple of scoops of protein powder-do you think I'll have to add more moisture if I do? If I do need to, do you think water would be sufficient? Or would you recommend something else? Any advice you could give would be appreciated =)
Thank you!
Alexis says
Water of almond milk is fine, yes id add a splash if youre doing protein!
Amy says
Thank you for these! My toddler and I both love them. They might become a staple in our freezer.
Michelle says
Hi - They look so yummy. Will try baking them today. Do you know if they are ok to freeze? Or how do you store them?
Thanks allot and happy day, Michelle
Alexis says
Hey Michelle, yes they are fine to freeze once they're cool. Just pop one in the microwave to defrost or let it sit in the fridge overnight. Store them in an air-tight container in the fridge once cool.
Anouk says
And then there are those who have an empty fridge because 'the store has a great refrigerator' or, 'but I usually eat out'. But what about breakfast? Or snacks? Or vegetables? How is there no food??
Non Foodies, don't get them.
Great post btw, looks like an awesome, nutritious snack as well!
Mario says
I made these and the one tip I would offer is to add the vanilla into the wet ingredients, I don't know if you mentioned that, but i pored mine (not thinking about it) right onto the oats only for it to be absorbed and not distributed, I added more so i wouldn't lose the flavor. I'm waiting for these babies to come out of the oven, so excited!
Alicia B says
Do you think you an egg could replace the flax seed? I'm assuming the flaxseed is the binder.
Jordana says
Thank you for this recipe! I used real eggs and also used shredded apple in place of the zucchini. These were delicious. My 12 month old and I both love them!
Kayla M says

Brit says
These muffins are amazing!! Incorporated this into our morning breakfast routine. Thank you for sharing.
Vicky Morris says
Just wondering about the amount of baking powder - a Tbsp seems like a lot. Is that what you used?
Thank you!
Alexis says
I've gotten very close to feeling like I'm going to kill someone if a smoothie doesn't meet my face. Kind of scary.
Alexis says
Awww thanks, Jenni! What a sweet comment. Sending hugs!
Alexis says
You're so welcome! I think you're gonna love these! Throw some chocolate chips in for the kiddos 🙂
Alexis says
Fabulous! I'm contemplating adding chocolate chips next time. Never a bad idea.
karina says
I made these this weekend to have as snacks for the week and they are already gone! This recipe will definitely become a regular in my rotation 😀 Thanks!!
Madeleine says
These look like the perfect thing to use up my extra zucchini, but I have one question: Do you have an idea of how much sugar is in each muffin?
Madeleine says
No worries! I just made them and loved them, by the way. And with just one of me and a handy-dandy freezer, I have breakfast lined up and ready-to-go for weeks!
Jenni says
You always crack me up -- I love how you write! xo 🙂 Thanks for the great recipe and for the laugh I always need! Love from South Florida.
