Mountain Thunder Oatmeal Cookies. Vegan, Oil-free, Sugar-free and Gluten-free!

Have you ever heard mountain thunder? It starts with a bang and then rolls… and rolls… and rolls—through the valleys, echoing off the surrounding mountains and finally settling somewhere in a quiet cove… like where I live! That’s what I heard while I was sleeping (trying to sleep) last night and early this morning. And that mountain thunder was the inspiration for these yummy cookies!

Loaded with nutrition, these mammoth treats will thunder through your body with health-promoting goodness. And they will stand by you, rolling on and on to keep you fueled. Perfect to take along on a hike or a road trip, or to grab in the morning on your way out the door to create a great day.


~ dry

  • 2 cups rolled oats
  • ⅓ cup oat bran
  • 2/3 cup brown rice flour
  • 2 tsp baking powder
  • 2 tsp baking soda
  • 2 tsp cinnamon
  • 1 TBS maca powder
  • 1 TBS chia seeds
  • 2 TBS flax meal
  • ½ cup raw sunflower seeds
  • ½ cup raisins
  • ½ cup goji berries
  • ½ cup cacao nibs (or vegan chocolate chips)
  • 1 cup chopped walnuts

~ wet

  • 3 large bananas
  • 1 cup dates, pitted
  • 2 tsp pure vanilla extract
  • ¼ cup plant-based milk


  1. Preheat the oven to 350° F.
  2. Line a cookie sheet with parchment.
  3. Combine all dry ingredients and mix well.
  4. Place all wet ingredients into the food processor and process until well combined. 
  5. Pour the wet ingredients into the dry and mix well. The dough will be quite thick. Let stand for about 15 minutes.
  6. Using a ¼ cup ice cream scoop, drop the dough onto the sheet. With wet hands, pat them down to about ½” high and 3″ in diameter and shape them a bit. Nine cookies will fit on a standard sized cookie sheet.
  7. Bake for 15 minutes.
  8. Let cool for about 30 minutes and serve.

Makes 18 giant cookies. Enjoy!

Healthy trails,

    I made them today because I love the ingredients. I made cookie size rather than "thunder" size and it all worked out well. The taste is good but the texture is a tad slimey. Maybe cut back on flaxseed and chia? Any thoughts?

    Hi Trix,
    Hmm. I'm surprised. Mine were not slimy in the least. And since you made them smaller, it's all the more a mystery! Did you follow the recipe exactly? Did you use flax seeds or ground flax (meal)? Whole seeds could contribute to that texture. Well, for sure you could try leaving the chia seeds out. But the flax meal is what binds them so that's needed. Sorry I couldn't have more suggestions for you!

    These look yummy! I have tried several of your recipes with great results. Thanks!
    One thing, though: I love to pin my recipes onto my pinterest board, and I can't get your pin button to work. ???

  6. Helyn says:

    Thanks, Charlene! The button worked for me. Are you using the button at the bottom of the post? It's underneath the "Print Friendly" button … just hover over the red "+" symbol and you will see it in a pop down list. Hope this helps!

    Hi Helyn!
    You created another awesome cookie!!!! These cookies are fantastic! The taste, the texture, you really put it over the top with this recipe! The chewiness of the goji berries and raisins, the crunch of the walnuts and sunflower seeds and don't forget the cacao nibs which IMO are the extra special delight in these cookies!!! The flavor is so wonderfully balanced, 3 bananas but no overpowering banana taste. Sometimes oats and bananas in cookie/bar recipes (On other sites, never Helyn's!) leave the finished product with a "gummy" texture, but not in this recipe! Each bite is a different taste treat! Next backpacking trip, a batch of these are coming along! They will be awesome fuel for hiking in the mountains.

    I followed the recipe exactly, (except my chia seeds were ground like the flax meal). My ice cream scoop is 1/8 cup size, so I was able to get 24 cookies out of the batch.

    Have a suggestion to the "slimy cookie" issue that Trix had. When shaping the cookies, could you have had too much water on your hands/fingers? Maybe it made them too wet? The first cookie I shaped was wetter than the others and it was a different texture after baking. Just a thought.

    Wow! Thanks so much for the accolades, Dru! I'm so happy you enjoyed them. Good tip on the issue that Trix had, too. Happy cookie trails!!! 🙂

    Made these over the weekend. Was missing some ingredients so replaced the oat bran with quinoa flakes, the flour with half buckwheat and half teff, skipped the raisins and goji berries and then replaced the cacao nibs with carob “nibs.”

    They were great. Just sweet enough to enjoy and filing enough to satisfy but not so sweet that they trigger overeating. Thank you!
