If your mornings are hectic, this make ahead breakfast oat bars are a great option! This Starbucks copycat recipe is so easy to make at home, and every bite is extra delicious! If oat bars are your favorite Starbucks treat, you’ll love this healthier homemade version!
Ingredients & substitutions
- Quick oats: These quick cooking oats, also called 1-minute oats can literally be cooked in that little time so they result is a chewy soft texture and are best for the recipe. You can use rolled oats, but make sure to grind them in a food processor first. Do not use steel cut oats. If gluten-free, use GF certified oats.
- Butter: Butter adds richness and helps to hold the oats together. Use unsalted butter, if you use salted, decrease the amount of added salt. Any plant-based butter would work perfectly in this recipe too.
- Light brown sugar: The molasses in the brown sugar adds a wonderful rich flavor. You can use white granulated sugar if you are in a pinch.
- Maple syrup: Maple syrup adds a nice earthy sweetness. Honey will also work well if you prefer.
- Milk: We used unsweetened almond milk for these oat bars, but any plant-based or dairy milk will work well.
- Vanilla extract and salt: To sweeten and round out the flavor of the oat bars.
How to make Starbucks oat bars
- Melt the butter, brown sugar and maple syrup in small saucepan. You can also use the microwave to make it faster.
- Whisk together until smooth and and then whisk in the milk and vanilla extract.
- Pour the butter mixture into the oat mixture.
- Stir to combine.
- Press the mixture into a lined square baking pan.
- Bake until lightly golden and firm.
Tips for making the bars at home
- Use quick oats for best results. They soften and cook quicker than rolled oats to result in a chewy tender texture that resembles the Starbucks recipe.
- Line the baking dish with parchment. Allow the parchment to hang over the sides of the pan so that the baked oats are easy to remove to cool and slice.
- Allow the oats to cool. If you cut into the baked oats too soon, they won’t be set. Let them cool in the pan for 5 minutes before transferring to a cooling rack.
- Add in some extras. Make these Starbucks oat bars exactly to your tastes by stirring in some chocolate chips, dried fruits or nuts to the oat mixture before baking. Or finish them with a drizzle of melted chocolate!

Love! Thank you so much. I didn’t have all the ingredients on hand, luckily my substitutions worked great. I used coconut sugar, agave syrup, and a few drops of english toffee stevia to bump up the malt flavor that brown sugar would have. Delish.
These were delicious! I never knew Starbucks had oat bars. But I was searching to find an oat bar recipe and I stumbled upon this one and I’m glad I found it. It was so hard to wait for them to cool off lol.
LOl, it is hard to wait to eat them! So glad you liked them!
Just wanted to give you some positive feedback and thank you for your time taken to post this recipe. It’s what I really needed.
Thank you so much, Lavern! I really appreciate it!
Just wondering about this sentence…
(From the recipe). Bake until slightly golden brown, rotating halfway through, 20 minutes.
I would have worded that sentence this way, “Bake for a total of 20 minutes – Or until slightly golden brown. Rotate at the 10 minute mark.
Oh, thanks for the feedback, and I see how your wording works too. The way I worded it is the acceptable method according to the publisher style guide that I follow.
Seriously?? You came here to comment on the way a recipe is worded?? It makes perfect sense just the way it is-smh
I have made these twice and they taste yummy. My issue is that they are quite crumbly and fall apart as I cut them. Any advice? Thanks.
Hi Janine! So glad you like the oat bars. I am sorry to hear that they aren’t sticking together well for you. If they are falling apart, they may be getting slightly overcooked. Is it possible your oven runs hot? As in, the temperature may be a little bit off even though you set it at 325, but it’s really over that temp? Also, when are you gutting them? When they are cooled or still warm?
The bars turned out well but they turned out a little pasty. I added an extra 5 minutes of baking and they colour really didn’t change, which is not a big deal obviously. The are good enough to make again for sure but next time I’ll only put 1 cup of the oaks into the food processor. I cut them into 16 bars, so about 1/2 of the size of a Starbucks bar, which is a better size for me. At $3.95 a bar here in Canada and $7.15 for a grande soy milk 1/2 sweet vanilla latte (no longer a regular treat at these prices) these bars are, and will be, a welcome way to treat myself and save a whack load of hard-earned $$$
Hi Andre, glad you like the oat bars. I am sorry they turned on pasty. Maybe try increasing the oven temperature to 335°F next time and see if that helps. Maybe your oven runs a little cooler than mine type of thing. Let me know if that works!
Just made these and they turned out really good. I did add about a half cup of peanut butter and some walnuts to mine. They have a nice chewy texture but are a little oily…maybe not so much butter next time, what do you think? I also melted Hershey kisses on top bc I didn’t have chocolate chips. Really satisfying and filling.
Hi Nichole! I am so glad you enjoyed the oat bars! Love the idea of adding the PB and walnuts! I suspect that the natural oil in the peanut butter combined with the unsalted butter contributed to that oily mouthfeel. I would cut the butter to 1/4 a cup next time if you add the PB again.
Thank you so very much for this recipe!!!!
so very delicious and nutritious my wife
kids love it, especially with chocolate chips.
You’re so welcome! That’s great to hear!
SO good!! SO easy!! SO healthy-ish!! Thanks for this great recipe which I easily converted to a vegan format. I always have these ingredients on hand so I’ll be making them over and over, and that’s for sure 🙂
Thank you so much! I’m so glad you were able to make it work and enjoyed. Yay!!
I would like to know how you made the vegan.
Did you use vegan butter?
Not sure if my first reply went through so I’ll try again.
I used Becel vegan margarine 🙂 As well, I used oat milk, not almond milk, because that is what I had on hand.
Thanks so much 🌹💞
Love! This recipe is a keeper. I only had low carb brown sugar and maple syrup substitute so I’ve made the recipe with those and it’s delicious. It’s my third time making them in as many weeks. So quick to make and so convenient to pack for lunches and snacks. A thousand thanks.
Thank you so much! I love that!
I used Becel vegan margarine 🙂 As well, I used oat milk, not almond milk (because that is what I had on hand).
I love your oat bar recipe! I’ve made them about 4 times in the last month. Can’t get enough. So tasty!
That is amazing! I love that!
I altered them a tad to make them “lactation oatmeal bars!” Oatmeal itself is a galactogogue, so I just added brewers yeast and flax seed to increase that! I also added some cinnamon and used sugar free maple flavored syrup. I have to make two batches at a tile because my littles like them too! Yum!
Glad you were able to make it work and that you all enjoyed!
Can I sub in 1% milk for the almond milk? Thanks
Very, Very good. And very easy! Good for when lots of friends come over and need a healthy-ish snack
Thank you so much! This would be perfect!
These bars are certainly very delicious, but they really don’t have that drier texture or the slightly salty taste of the Starbucks ones. I found them yummy, pretty darn close to Starbucks, but chewier than I was hoping for. Thanks for sharing!!
Thank you! Because of the quick cooking oats, they result is a chewy soft texture. For a drier texture, it may help to bake it for a little longer.
Made these, and was a little disappointed. They were extremely dry, and not a lot of flavor. I’m not sure if it’s because it didn’t have eggs? Either way, won’t be making again.
It shouldn’t have turned out dry because the butter helps keep it moist. Do you think it could’ve been overcooked?
I didn’t care for these. They tasted bland and fell apart when I cut them. Maybe if I added chocolate chips.
They may have been slightly overcooked if they fell apart when being cut. Definitely customize these to your liking with add ins such as chocolate chips, dried fruits, or nuts.
Made these today exactly as written and they are delicious! Two thumbs up from my 10 year old son and the hubby too. Next time I may substitute honey for the maple syrup to experiment.
That’s amazing! Love that you all enjoyed it!
I just made this Starbucks Oat bars and I absolutely love them. it tastes so delicious. This breakfast choice is best for me right now as I work at the hospital and sometimes don’t get to eat breakfast. Thanks Yumna!
That’s amazing! Yay!! You’re so welcome!
I’m quite impressed how these turned out actually. I added oatmeal I had that included some cinnamon, apples, pumpkin seeds and flax seeds to the regular oatmeal and put it in the blender to make it more fine. Turned out great!
Yay! That’s a fun way to switch it up.
Hello! Would these work with GF oats, which is what I use for oatmeal?
Yes, it will work!
These were amazingly delicious. I had previously made the peanut butter granola bars for my son’s lunchbox & he loves them. I began making these Starbucks ones for my mom because she’s allergic toto nuts & peanut butter. The first batch I made, I mixed in chocolate chips. They turned out devine. This time I didn’t have honey so I substituted it with date syrup & OMG! THEY WERE AMAZING. Thanks for for easy to make nutritious recipes
Thank you so much! So glad you all enjoyed it!
It was so good! I added chocolate chips and sprinkled MILO on top!
Thank you! Love the sound of that!
Is it possible to add additional flavouring to these? like cranberries, hazelnuts and chocolate chips??
Yes! Make these Starbucks oat bars exactly to your tastes by stirring in some chocolate chips, dried fruits or nuts to the oat mixture before baking. Or finish them with a drizzle of melted chocolate!
These are outstanding! They taste exactly like the Starbucks oat bars. They were so quick and easy to make too. We cut them, wrapped individually and froze them. When I make them again, I will double the recipe! Thank you! My family loves your recipes ❤️
Thank you so much!! That’s so great to hear!
I just made them, they taste absolutely fantastic! I hope my son likes them.
Yay!! Hope he does too!
Can the butter be replaced with anything other than coconut oil or plant-based butter.
I have not tried it with any other substitute.
Just made these during my WFH lunch break. I hope my family likes them… and if they don’t, too bad, more for me!
Glad you at least enjoyed them! Hope your family does too!
Hello! I would like to make these using oat flour. How much oat flour do I need (instead of blending oats)? thank you!
I would use 2 cups of oat flour and 1¾ cups oats.
Would it be ok to sub in unsweetened apple sauce for the maple syrup or would that change the consistency too much? Can’t wait to make these for my family!
You could try that! I think it would just reduce the sweetness, and it shouldn’t affect the consistency too much.
Hi! Your recipe looks delicious! Do you think I could substitute regular milk for the almond milk?
Thank you! Yes, you can make that substitute.
Made these yesterday 🤤 So good!
Yay! Love that!!
Could you use rolled oats instead?
Yes! You can use rolled oats, but make sure to grind them in a food processor first.
Hi Yumna! This looks like a great recipe – but I just want to clarify. Is the total bake time 20 minutes, rotating half way through, or 40 minutes, rotating at 20 minutes?
I’d really like to print your recipes – but do you think it would be possible to list /show the equipment used with links ABOVE the recipe itself? The extra space it takes up causes the recipe to require part of a 2nd page, therefore wasting paper.
Thank you! The total bake time in 20 minutes, and you will rotate it at the 10 minute mark. If you scroll to the recipe card, there’s a printer icon. When you click on it, I have it formatted in a way to print on 1-2 pages maximum with no images, no large font or anything that takes up too much ink. Can you try that? It should work fine.
I love this recipe! I’ve made it twice already this week. 🙂
Do you think it would work with honey, agave nectar, or molasses?
Thank you! Yay!! Yes, I think it would work.
I made this today, seriously was amazing and so easy. Let’s just say I am no longer buying granola bars.
Thank you so much! Homemade for the win!
What texture should these have to be done? Toothpick test? Just not jiggly? My oven is finicky so I have to adjust time for almost every recipe 🙂
They result is a chewy soft texture!
I made them this morning, after I saw the recipe on IG yesterday. Super easy, very tasty. Next time I might add chocolate chips. Thank you for another great recipe!
Yay!! Love the idea with the chocolate chips. You’re so welcome!
Just made these and turned out great using Honey, but will try Maple Syrup next batch to try getting it to more authentic oat bar taste. Thanks for sharing!
That’s amazing! Let me know what you think once you get to try it with the maple syrup too!
