Vegan blueberry oat muffins, made with ease in a blender! Made with oats and raw cashews, they are oil-free, gluten-free, and so delicious!
Following in a trend I have been setting for myself for, oh, the past 5 years or so, I offer you a holiday-themed recipe…post-holiday.
Unlike past holidays, I will no longer beat myself anymore for this shortfall. Instead, I’m giving my tendencies a positive spin. I like to celebrate a holiday on the holiday, and, even better, continue enjoying the holiday for several days after. It takes a lot of pressure off of making a single day perfect (this is an especially good trick for birthdays; I highly recommend the birthday week).
Hence, to commemorate this 4th of July week, I offer my (patriotic) blueberry muffins, made vegan, oil-free, flourless, and gluten-free with the help of oats and raw cashews. They are:
- Vegan
- Gluten-free
- Oil-free
- Flourless
- Super-easy to make
- Delicious!
The blueberries this summer have been nothing short of glorious. I have been eating them by the fistful and freezing hoards, too.

But there is something uniquely luscious about blueberries baked into a sweet, tender batter. The heat intensifies the flavor, and the contrast between golden crumbs and inky berries in a single mouthful is nothing short of summer bliss.
Make the Oat & Cashew Batter in a Blender
This easy muffin recipe is just such bliss. The batter could not be easier to prepare: simply blend oats and raw cashews in a blender until completely smooth (along with sweetener and leavening). The cashews deliver the fat, as well as structure to these tender, egg- and gluten-free muffins.

Divide the batter between lined muffin cups, avoiding the temptation of filling the cups too full! If the cups are filled with too much batter, they will not rise properly. Use all 9 cups for the batter.
Once the batter is divided between the cups, divide the blueberries between the cups.

Use Other Fruits and Berries
Blueberries work best in this recipe, but blackberries and raspberries are great, too. Strawberries will not work; they have too much water to work in this recipe exactly as written, so save those for eating alongside.
Other summer fruits, besides berries, can work, especially stone fruits (e.g., apricots, nectarines and peaches).
These are worth turning on the oven, no matter the heat and humidity–happy eating, everyone!

Hi, I made these today and they’re so yummy out of the oven. My blueberries were quite sour so I think the muffins themselves could have used a tad more sweetness but I think they’re perfect. My daughter and husband tried them and they were impressed especially since there’s no flour or oil. Will definitely be making again! Thank you
That’s wonderful, Carol! I am so glad the whole family likes them 🙂
This recipe is the bomb. It’s super easy, sugar free (I used date syrup), oil-free and gluten-free. You’d think they wouldn’t be very tasty, but they definitely are!
Bombs away!!! 🙂 So glad you love these, Angela.
Could white beans replace the cashews?
Alas, no, they will not work in the same way for baked goods.
I made these muffins yesterday. I replaced the water with apple juice.
I made them again today. Instead of cashews, I used hemp hearts. Both sets of muffins are really spongy and delicious. Thanks for the recipe.
Wonderful, Fareeda!
Would frozen blueberries work in this recipe? Sounds delicious and easy !!
Yes, definitely!
These are wonderful, thank you! I use frozen blueberries (ones that I freeze myself. the ones from the store are often very juicy when thawed). I that them part way and they work perfectly!
These are delicious! Thanks for the easy and wonderful recipe, Camilla, the whole family loves these.
