No Bake Blueberry Oat Bars (5 Ingredients + Vegan)
All you need is 5 simple ingredients to make this delicious no bake breakfast snack bar. Way better than buying prepackaged granola bars from the supermarket! They come together in 15 minutes. You just need to give them some time in the fridge to set!

The filling is super easy to make with just blueberries and water. Just cook the fruit down but don’t completely mash it up – leave some pieces whole. You can also add a drop or two of maple syrup while its cooking to sweeten it more – but I didn’t.

You can use any nut butter like almond butter or sunflower seed butter to make this! You can also use any liquid sweetener like honey instead of maple syrup.

Hi, can these go in the freezer, if they are made a day or two ahead of when they are going to be served?
Hello! Yes, of course!!
Hi is there a substitute for the nut butter?
Hi Georgi, a seed butter would work
this is so good, so healthy. I’m doing it in portions & ready to carry with me to work.
Hello, that’s awesome! Thanks for the kind message!
Oh man—these are so good—thank you! The only change I made was I used almond flour instead of oat flour and that worked well. Next time I’ll go with oat flour. Oh—I also added a tablespoon of ground chia seeds.
I will absolutely make these again!
