A delicious on-the-go breakfast

We love Soft-Baked Oatmeal Breakfast Bars–they’re our favorites for grab-and-go breakfast or snacks. They’ve got great ingredients, and are filling, tender, soft, and ultra chewy. These bars taste like a mash-up of soft granola bars and a bowl of oatmeal; you’ll get wholesome-tasting, surprisingly-filling oat-filled bars.

Thanks to the nut butter and plenty of oats, these bars have substantial protein and fiber,  and that helps your body feel fuller for longer.

How to make Soft-Baked Oatmeal Breakfast Bars

These bars are one of the easiest recipes ever. They’re made in one bowl and can be whipped together in minutes.

  1. Combine all the ingredients (except the dark chocolate) in a large bowl and mix to combine.
  2. Coarsely chop the dark chocolate (we want some in every bite!) and add to the batter.
  3. Mix the batter and then transfer to a lined 8×8-inch pan.
  4. Bake until lightly browned at the edges and firm in the center.

Combining all the ingredients in a bowl, mixing them together, and transferring the mixture to a baking pan.

Soft-Baked Oatmeal Breakfast Bar ingredients

  • Old-fashioned oats: The oats make up the base of these bars and give them that soft chewiness. Make sure to use old-fashioned oats — quick oats are too processed and will make the bars overly dry; steel-cut oats won’t soften enough.
  • Oat flour: No need to buy specialty flour. Oat flour can be made with quick or old-fashioned oats; read more on this below.
  • Cinnamon: This spice adds a really nice complementary flavor to the oats, but it’s completely optional. If you aren’t a cinnamon fan, leave it out!
  • Salt: Salt helps balance all the flavors in these Soft-Baked Oatmeal Breakfast Bars.
  • Peanut butter: Peanut butter contributes structure and stability (as well as protein).
  • Coconut oil: The coconut oil gives the bars a nice flavor and moistness.
  • Honey: We sweeten these primarily with honey, and natural sweeteners are always a great choice.
  • Light brown sugar: We’ve also got a little brown sugar in there; we found the bars needed a little more sweetness, and were too wet with 100% honey, so we added 1/3 cup.
  • Vanilla extract: This ingredient contributes to a nice subtle flavor.
  • Egg + egg yolk: The egg provides stability to the batter and adds flavor and protein. The second egg yolk adds additional structure and flavor. Use the leftover egg whites in this egg wrap!
  • Dark chocolate: Dark chocolate has antioxidants in it, among other benefits. If you aren’t a fan of dark chocolate, you can use milk or semi-sweet chocolate, but it will make the bars a bit less healthy. Alternatively, chopped nuts can be added instead (or in addition).

How to make oat “flour”

If you have quick oats or old-fashioned oats, you can have oat flour ready for in flash.

  1. Place the oats (old-fashioned or quick oats–not instant or steel-cut ones) into the bowl of a food processor or a small blender jar.
  2. Pulse the oats until ground into a powder-like consistency that resembles regular flour.
  3. Stir the oats around if needed, to be sure all the oats are finely ground.
  4. Make sure to measure your oat flour after it’s been turned into flour.

Soft-Baked Oatmeal Breakfast Bar tips

  • Line the pan with parchment paper and leave an overhang for easy removal.  Sticky batter like this will be nearly impossible to remove without the parchment paper. If you don’t have parchment paper, I recommend thoroughly greasing the pan.
  • Let the bars cool. You may be tempted to eat one straight out of the oven (and hey — you do you!), but these bars are crumbly and a bit gooey while hot. They thicken up a lot as they cool and become easier to cut and serve.
  • Don’t overbake. Remove the bars when they are slightly browned on the edges;  the middle and top of the bars may look a bit wet or gooey, but as long as the bars don’t jiggle when slightly shaken in the pan, they’re done. Overbaked bars won’t be very soft or chewy and will also lack flavor.

Quick Tip

Make sure the ingredients are gluten free. If you are gluten intolerant, make sure to check all the individual products to be sure they are indeed gluten free. Pay particular attention to see that they are processed in a facility that doesn’t have gluten; this will be indicated on the label. While these bars are naturally gluten free, some products aren’t processed in a strictly gluten-free environment.

Storage

Store Soft-Baked Oatmeal Breakfast Bars in an airtight container at room temperature, and they’re best enjoyed within 2-3 days of making. Feel free to warm individual bars for 5-10 seconds in the microwave if you like them warm.

To freeze: Wrap individual bars tightly in plastic wrap and then place in an airtight freezer-safe container. Thaw individual bars at room temperature, and if desired, warm through for 5-10 seconds in the microwave.

    I made these and they were delicious. I substituted gluten free flour for the oat flour (because I was too lazy to make the oat flour, lol)! They are soooo good! I’m gonna add walnuts last time which I think would be an excellent addition!

    1. Chelsea Lords says:

      So thrilled to hear these were a hit! Thank you!!

  2. Juliana says:

    I added in 6oz of cranberries! And they were absolutely fantastic!

    1. Chelsea Lords says:

      Great idea!

  3. Amanda says:

    Could I leave out the peanut butter or substitute it for something else.

    1. Chelsea Lords says:

      You could try using a roasted and salted almond butter

  4. Lindsay says:

    These sound great but if I want to try using all honey and no brown sugar, what would you recommend?

    1. Chelsea Lords says:

      I’m sorry I’ve only tested this recipe as written!

    Easy to make and doggone delish. I added some crushed flax seed as well.

    1. Chelsea Lords says:

      So happy to hear that! 🙂

    Soooooo goooood! The whole family is obsessed! They came out thinner than I thought though. Any ideas? Thank you for this! I will be making it often!

    1. Chelsea Lords says:

      Yay! So happy to hear that 🙂 Thank you! Did you use an 8×8 pan? As written I’d say they are pretty thin, the up close photos make them seem a little thicker I think!

    These bars are FANTASTIC!!! I use powdered peanut butter and changed the brown sugar to Stevia to reduce the calories, but it is still great! THANK YOU SO MUCH for sharing this recipe. I have tried a few different oat bars, but this one is getting printed out so I don’t loose it.

    1. Chelsea Lords says:

      I am so happy to hear this Lori! Thank you so much for your comment! 🙂

    Mmm, the smell of peanut butter from the oven while baking! It is beautifully baked – soft and chewy, to perfection! We enjoyed it with a cup of coffee or milk. Thanks for the recipe, I should try others too!

  9. Kristy says:

    These are delicious!! Any chance you can come up with a copycat recipe for their banana bread & dark chocolate version of these soft baked oatmeal bars? 😉

    1. Chelsea Lords says:

      I will add that to my list!! Thanks Kristy 🙂
