Ingredients & substitutions

  • Quick oats: These quick-cooking oats, also called 1-minute oats, can literally be cooked in that little time, so they have a chewy, soft texture and are best for the recipe. Do not use rolled/old-fashioned oats or steel-cut oats. The bars have a hard time sticking together. 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.

Tips for making the bars at home

  1. 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.
  2. 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.
  3. 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!

Frequently asked questions

Can you make them vegan?

These oat bars contain butter so they are not vegan. But when tested with plant-based butter, they work out perfectly so it’s the only change needed to make them vegan!

How long do they last?

These breakfast oat bars are great for meal prep. Once cooled, store them in an airtight container in the fridge for up to 5 days. You can enjoy them cold, at room temperature, or warm them through slightly.

Can you freeze them?

Yes, these will freeze well for up to 2 months, so make a double batch. Freeze the bars solid on a baking sheet before transferring to a container or bag, or, wrap individually in parchment. Thaw in the fridge or at room temperature.

    After reading the comments, I added 2 eggs and 1/4 tsp salt and they came out soft and intact. Amazing! Also put in less maple syrup

    1. Yumna says:

      Thanks for the feedback!

  2. Nadine says:

    I’ve never tried the original sbux version but I LOVE this recipe. I added a dash of cinnamon and it was AMAZING!!! Thanks for the recipe ❣️

    1. Yumna says:

      So glad you loved them!

  3. PJT says:

    Can I sub Almond milk for unsweetened Oat milk?

    1. Yumna says:

      Yes, that will be just fine!

  4. Michael says:

    I’m not understanding something. Recipe calls for 7.5 cups of quick oats. Instructions say to grind 2 cups of the oats until super fine then add in the remaining 1 3/4 cups of oats. 2 cups plus 1 3/4 cups equal 3.75 cups. What happened to the other 3.75 cups?

    1. Yumna says:

      Hi there, thanks for your comment! The recipe calls for 3 3/4 cups of quick oats. I think you may have accidentally set the scale of the recipes to “2x” which may be where you are seeing 7.5 cups of quick oats. Hope that sorts out any confusion.

  5. Kelly says:

    These are fantastic!! At first they did crumble but once they set up and stored in fridge, stayed together perfectly! Thanks for sharing this recipe! I added cinnamon and raisins.

    1. Yumna J. says:

      Thank you so much, Kelly!

  6. Modeeha says:

    How much does 2c quick oats end up being when ground down? I already have some gf oat flour and wanted to use that instead, but not too sure on the exact measurement I should be using.

    1. Yumna J. says:

      Hi Modeeha, I am not sure either as the ratio would be different and I have not made these with oat flour. If I was to try it I would start with 1 and 1/4 cup of oat flour and then test from there.

  7. Pauline says:

    Very crumbly, but quite tasty. I was hoping to be able to slice into bars. They just fell apart. Might be good to use like a granola topping over yogurt.

    1. Yumna J. says:

      So sorry to hear that your bars didn’t stick together for you. Using it as granola is a great option! I am going to retest this and see what’s going on with them.

      1. Josee says:

        My first batch was too. Just reduce your cooking time by 3-4 minutes. They were perfect

        1. Yumna says:

          Thanks for this feedback!

  8. Cheri Moore says:

    Made your recipe for the Oat Bars (copycat Starbucks) and I liked them but felt they needed something extra. So, I melted 1 cup of semi-sweet chocolate chips with 1 tsp. oil in the micro-wave, stirring until chocolate was smooth. Then I covered the oat bars evenly with the chocolate. By the second day, the chocolate had hardened and the bars are tasting wonderfully, according to my husband!

    1. Yumna J. says:

      Love that idea! So glad to hear that you and your husband are enjoying them.
