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.

    Is there something that can be used instead of peanut butter and coconut oil for a *nut free version??

    1. Chelsea Lords says:

      I’m sorry I haven’t tested this recipe without those 2 ingredients!

    2. Amber Da Ponte says:

      You could use tahini in place of the nut butter and olive oil in place of the coconut oil ๐Ÿ™‚ or even apple sauce if you want an oil free version :).

    3. Emilee says:

      I would try using butter instead of coconut oil and sunbutter as a nut free alternative

    This is a great recipe. I only made 1 change because I am not a chocolate lover (I know as a woman, this is hardly possible!!) but I substituted aronia berries. They worked really well and were even healthier than the original recipe. Thanks for the recipe.

    1. Chelsea says:

      Delish! I am so happy to hear you loved these soft-baked oatmeal breakfast bars! Thanks Coreen!

  3. Elaine Benson says:

    Can I use coconut sugar instead of brown sugar 4 these?

    1. Chelsea says:

      I haven’t tested this but I would imagine it’ll work just fine! Let me know if you give it a try! Thanks Elaine.

    These turned out great!! Love the soft texture. I reduced the sugar by 1/3 and they were still sufficiently sweet. Thanks for this recipe!

    1. Chelsea says:

      Yay! So happy to hear this! Thanks so much Holli! ๐Ÿ™‚

    These are amazing. Iโ€™ve been making this recipe for over a year and my children LOVE them. I make a triple batch every week. Since making these weโ€™ve discovered one of my kids has an egg allergy and adapting this to be egg free was super easy. these are a breakfast staple for us

    1. Chelsea says:

      I am so thrilled to hear this! Thanks so much Kara! ๐Ÿ™‚

    2. Emilee says:

      What did you use to make them egg free? A flax egg? I also need to make them egg free

    1. Chelsea says:

      I am so happy to hear this! Thanks so much Virginia! ๐Ÿ™‚

      1. Jenny says:

        Any suggestions if we donโ€™t have parchment paper? Really hope to try these!

        1. Chelsea says:

          I haven’t tested this without parchment paper, but I’d suggest oiling the pan and dusting it with flour before adding your dough as a good alternative.
