These no bake blueberry breakfast bars are healthy oatmeal bars with a juicy sweet blueberry homemade jam and crunchy oatmeal crumble on top!
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.

Love this recipe! So easy to make and tastes amazing!
Hi Jenny, thank you for trying the recipe and I’m glad you loved it!
Could I use almond flour instead of oat flour?
I’ve made this several times this summer, love it for breakfast! Mine don’t cut as cleanly as yours, they crumble. Should I add more moisture somehow?
Hi Peggy, make sure you’re using ONE ingredient peanut butter. The creamy, stir kind.
very good
Superb … and so easy!!
Hi Cathy, thanks for trying the recipe!
Can you use frozen blueberries or cherries?
Hi Cathie, I havent tried it with frozen but it should work no problem

Thanks for trying the recipe Joseph!
This blueberry bar is awesome! It is much healthier using oats and oat flour and no baking makes it quick and easy. Love it with yogurt in the morning or slightly warmed with ice cream … to make a lovely dessert. Thank you for the recipe.
Hi Cathy, Sounds delicious! Thanks for sharing your feedback!
I followed the recipe to the exact measurement. I don’t find them that good. They’re okay, but I wouldn’t make them again.

Hi Sushi, I’m sorry the recipe didnt work for you!
These blueberry bars are awesome! I do prefer making them with almond butter. I am going to try making them too with strawberries. Love the simplicity of the recipe. Thank you
Hi Cathy, thanks for trying the bars! I’m glad you love them!
I made these for the 10 hour drive to Charleston, SC in March. What a delicious treat! Also made a wonderful breakfast bite with morning coffee. Will experiment with sour cherries & apricots, because I cannot help myself! Thank You Stella!
Hi Juliana, that’s aawesome! I’m so glad the recipe came in handy for your trip!
I love blueberry anything, so I’m excited to try this recipe. I was wondering if I could use butter in place of the coconut oil and store them in the fridge? I think the butter would add a good flavor but I’m not sure of the purpose of using coconut oil instead of butter. Thanks!
