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.

  1. Sam says:

    These look good! I just bought them & has to find a recipe! What can I sub the whole wheat flour for?
    Thanks!

    1. Chelsea Lords says:

      Sorry Sam I haven’t tried this recipe any other ways than written!

  2. Sarah says:

    I made these as written, and they were very easy to make and had a fantastic flavour- the icing tastes amazing and the bars are not too sweet, so they pair well with the sweet icing. The consistency of the bars is a little too light/spongy- I think it would help to add some fat to the batter, either oil or melted butter. I might play around with fat ratios in order to keep the flavour the same but ideally to end up with a consistency more similar to that of a soft cookie.

    1. Chelsea Lords says:

      Thanks for the review and feedback Sarah! ๐Ÿ™‚

  3. priyanka says:

    is there any substitute for egg??

    1. chelseamessyapron says:

    Could you copycat the Banana & Dark Chcolate Soft-Baked Oatmeal Squares? I loved those ones but simply don’t have the time to try to make a copycat recipe for them.

    1. chelseamessyapron says:

      Hi August! I have my editorial calendar pretty booked and planned with recipes throughout the rest of this year but I’ll definitely put that on the list and see when I can get around to working on a recipe for them ๐Ÿ™‚

  6. Mary says:

    Thank you! I made these tonight for my kiddo who loved them!

    1. chelseamessyapron says:

      Awesome!! So thrilled she liked them! And great idea using a banana in these ๐Ÿ™‚

  7. Cindi says:

    Do you think you could double the recipe and put in a 9×13?

    1. chelseamessyapron says:

      I haven’t tried that so I can’t say for sure, but I don’t see why that wouldn’t work. You will, of course, have more batter and will likely need to cook it longer for it to be cooked all the way through.

  8. Kirsten says:

    How long do these last when stored?

    1. chelseamessyapron says:

      They are best within 2-3 days stored in an airtight container. The rest you can tightly seal and freeze ๐Ÿ™‚

  9. Erlene says:

    I’m looking for grab-n-go things for the kids to eat when school starts back up. This will be great and will be giving this a try.

  10. Jessica Greiner says:

    I love these bars so much!

    1. chelseamessyapron says:

      So glad to hear that! Thanks Jessica ๐Ÿ™‚
