A great wholesome snack!

These blueberry oatmeal bars are soft, chewy, and bursting with sweet-tart dried blueberries. They’re essentially a mash up of soft granola bars and a bowl of oatmeal — you’ll get thick and chewy, wholesome-tasting, oat-filled bars with this recipe.

These bars are quite healthy and can be made even healthier without the glaze if you’re watching sugar consumption.

Blueberry Oatmeal Bars ingredients

  • Old fashioned oats: the oats make up the base of these bars and are what give them that delicious oatmeal granola bar 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 blueberries and bars; feel free to reduce, omit, or increase the amount depending on personal preference.
  • Salt: this ingredient helps balance all the flavors in these blueberry oatmeal bars
  • Peanut butter: this ingredient provides structure and stability as well as protein to these bars. The peanut butter really makes these bars quite filling! I haven’t personally tested, but I do think a creamy almond butter would work nicely in these bars.
  • Coconut oil: this oil has become popular the last few years as a healthier alternative to butter and gives these bars a nice flavor.
  • Honey: these bars are mainly naturally sweetened with honey. Honey is rich in antioxidants and contains some nutrients.
  • Light brown sugar: I wanted these bars to be fully naturally sweetened, but they did need a bit more sweetness and were too wet with all honey, so we do use a little brown sugar in these bars — only 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 to these bars. The egg yolk adds additional structure and flavor. Use the leftover egg whites in this egg wrap!
  • Dried blueberries: make sure to use dried blueberries, not fresh or frozen, in these bars. Dried blueberries are typically found with any other dried fruits and/or raisins/dried cranberries in the grocery store.

How to make oat “flour”

If you have quick oats or old fashioned oats, you can have oat flour ready for these blueberry oatmeal bars in an instant!

  1. Place the oats (you can use old fashioned or quick oats) into the bowl of your food processor or small blender jar.
  2. Pulse the oats until ground into a powder-like consistency that resembles flour.
  3. Stir the oats around if needed to be sure all the oats are finely ground and there aren’t any full oats left. 
  4. Make sure to measure your oat flour after it’s been turned to flour and not in the original whole oat form.

Blueberry Oatmeal Bars tips

  • Line the pan with parchment paper and leave an overhang for easy bar removal. These bars will stick to the pan and be near impossible to pull out without the parchment
  • Let the bars cool: while it’s so tempting to eat one straight out of the oven (and hey — you do you) these bars are crumbly and a bit gooey while hot. They thicken up a lot as they cool. The glaze also will get overly melty and messy if drizzled on warm bars.
  • Don’t over-bake: 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. If the bars are over-baked they won’t be very soft or chewy.

Storage

Store these blueberry oatmeal bars in an airtight bag or container at room temperature. These bars are best enjoyed within 2-3 days of making. Leftovers can be frozen and later thawed at room temperature.

To freeze: wrap individual bars tightly in plastic wrap and then place individually wrapped bars in an airtight freezer-safe container.

Prep Time: 15 minutes
Cook Time: 25 minutes
Total Time: 40 minutes
Servings: 12 bars

Equipment

  • Baking pan 8 x 8-inch
  • Parchment paper
  • Blender

Ingredients 
 

Blueberry Oatmeal Bars

  • 1 cup old fashioned oats
  • 1/3 cup blended oats oat flour
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/3 cup creamy peanut butter
  • 1/4 cup melted coconut oil
  • 1/4 cup honey
  • 1/3 cup light brown sugar lightly packed
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 1 large egg yolk save the whites for another recipe or discard them
  • 3/4 cup dried blueberries

Glaze (Optional)

  • 3/4 teaspoon vanilla extract
  • 1/2 cup powdered sugar
  • 1/16 teaspoon salt
  • 1/2 to 3/4 tablespoon milk any milk works; I used whole milk

Instructions 

For the bars:

  • Preheat oven to 325โ„‰. Line an 8x8 baking pan with parchment paper with an overhang. (These will be near impossible to get out without it.)
  • To make oat flour, just place old fashioned or quick oats in a blender and pulse until they resemble flour. Measure after blending to make sure you have the right amount.
  • Combine all oatmeal bar ingredients except dried blueberries in a large bowl and stir until smooth and well combined. Add in dried blueberries and stir. Transfer batter to prepared pan.
  • Bake 23โ€“26 minutes or until set at the edges (it does look slightly wet in the center, but as long as it doesnโ€™t jiggle, itโ€™s done). The bars will firm up as they cool; be careful not to overbake.

For the vanilla drizzle:

  • Combine all glaze ingredients in a medium bowl, starting with only 1/2 tablespoon milk. Whisk briskly until a very thick glaze forms. Add up to 3/4 tablespoon milk if needed.
  • Transfer glaze to a plastic resealable bag and cut off the very tip. Once bars have cooled, drizzle glaze over the bars.
