Healthy Sourdough Brownies (Gluten-Free and Vegan Options)

Sourdough brownies are a delightfully healthy dessert. Packed with gut-healthy oat flour and chia seeds these sourdough discard brownies are delicious!

Healthy Sourdough Brownies

Oat flour, the star ingredient in our sourdough brownies, is an excellent alternative to regular wheat flour for those avoiding gluten and boasts impressive health benefits.

Oats are rich in soluble fiber, particularly beta-glucans, which support gut health by promoting the growth of beneficial gut bacteria. This soluble fiber also helps to regulate bowel movements and maintain a healthy digestive system. Additionally, oat flour is an excellent source of vitamins, minerals, and antioxidants, making it a wholesome choice for a guilt-free treat.

Incorporating chia seeds into our brownie recipe takes it up a notch in terms of both nutrition and texture. Chia seeds are tiny powerhouses of nutrition, loaded with fiber, protein, omega-3 fatty acids, and various essential minerals.

When mixed with liquid, chia seeds form a gel-like substance that acts as a binding agent, making them a perfect egg substitute in vegan baking. This gel also aids digestion by promoting a feeling of fullness and assisting with bowel regularity.

So, not only do chia seeds contribute to the fudgy texture of our brownies, but they also contribute to your overall well-being.

Sourdough Brownies

Before we dive into the recipe, let’s take a moment to appreciate the rich history of brownies.

These delectable treats originated in the United States during the late 19th century. The exact circumstances of their creation remain shrouded in mystery, but the first-known recipe for “brownies” appeared in an 1896 Sears, Roebuck & Co. catalog.

Since then, many variations of brownie recipes have been published in books and online, becoming a beloved dessert worldwide. So I’m happy to present our unique twist on this classic with a gut-friendly and wholesome approach.

How to Make Vegan Sourdough Brownies

Now, you might be wondering about our brownies’ “sourdough” aspect. Fear not, as the flavor is definitely not sour!

This recipe is simply a way to repurpose your sourdough discard, reducing waste and infusing the brownies with a subtle tang that balances the sweetness.

Sourdough discard is the portion of sourdough starter removed and discarded during feeding. Using it in our brownie recipe adds depth of flavor and makes the most of our sourdough baking endeavors. The starter does not make the dough rise in sourdough discard recipes, so you can bake the brownies immediately after mixing.

If you want to ferment the batter overnight in the fridge, you can try it, but it may change the texture of the brownies quite a lot.

Fiber-Rich, Healthy Brownie Recipe

Whether you’re gluten-free, vegan, or simply seeking a deliciously wholesome treat, these Sourdough Brownies will please.

With the health benefits of oat flour and chia seeds and the use of sourdough discard, you can relish each bite, knowing it supports your gut health.

So, gather your ingredients, preheat your oven, and let the baking adventure begin!

    The brownies look so delish! I want to try baking it, but I was wondering if you have the measurements in grams for it, Kaitlynn? Thank you so much in advance!

    Can coconut milk be used? And why chickpea flour?

      I haven’t tried it, but it might work. I developed the recipe with chickpea flour because that’s what I had.

      I baked it last night n ate it this morning. I added dried cranberries, dried blueberries, sunflower seeds, pumpkin seeds and chocolate chips. It is soft and good. It is a keeper.

A lot of people think vinegar kills all microbes b A lot of people think vinegar kills all microbes because shelf stable pickles do not contain microbes. But with shelf stable pickles, it’s the pasteurization/sterilization via hot water bath or pressure canning that makes shelf stable pickles free of microbes.

Hot hot hot acid in a pressurized environment does kill, well…most microbes. 

Think about “refrigerator pickle” recipes, though. They need to be stored in the refrigerator because vinegar alone doesn’t stop fermentation.

Fridge pickles are made without pasteurization/sterilization (canning) so they will wild ferment without refrigeration, and not necessarily in a good way because there’s not enough salt. 

All vinegar is made via fermentation too, and vinegar fermentation involves acetic acid bacteria, but also a ton of LAB, mainly Lactobacillus, Pediococcus, and Leuconostoc (the same genera you’d find in fermented veg.)  I linked a reference paper in my fermented mushroom recipe blog, so you all can read about the LAB involved in vinegar fermentation. 

Try 🍄‍🟫googlin’🍄‍🟫“fermented mushrooms” and you’ll see my recipe, it’s the first result (usually) 🤗

I will not ever wild lacto ferment just beets agai I will not ever wild lacto ferment just beets again lol. Mixing with cabbage for beet sauerkraut is the best though! 

“Lacto fermented beets” was the first ferment I tried to make after learning sauerkraut in college. My best friend Sidney came over and we used these gorgeous beets from the farmers market, with 2.5% salt, and some spices. Well, it ended up tasting like beet moonshine and it was just… not good.

But it was a conduit for learning. Those beets were my first lesson in how different sugars and growth in the rhizosphere vs the phyllosphere influences fermentation. 

Cabbage and the cabbage microbiome offer a lot to balance out beets in fermentation, and I think mixing into a sauerkraut is the only way to go for lacto fermenting beets! 

Try googlin’ “beet and red cabbage sauerkraut” and you’ll see my recipe, I’m Cultured Guru.
Squash is the secret ingredient! My Roasted Butte Squash is the secret ingredient!

My Roasted Butternut Squash Hot Sauce recipe is free on my website! I didn’t cook this one, so yes it’s still probiotic.

When lactic acid bacteria ferment the starches in winter squash, they naturally convert them into emulsifying compounds called exopolysaccharides. So when we blend our hot sauce after fermentation, there’s no watery separation in the bottle. Roasting the squash with the garlic for the recipes also adds such good flavor! 

Definitely make sure it’s fully fermented and not bubbling anymore before you blend and bottle. Otherwise, it’ll carbonate in the cute little hot sauce bottles.

And the knife stays in the box. GOOGLE “sourdoug And the knife stays in the box. 

GOOGLE “sourdough king cake” my recipe is the first one! 👑☂️💚✨

If you’re like me and prefer from scratch, homemade everything, you’ll definitely want to try this king cake for Mardi Gras! I used organic naturally dyed sprinkles and all that jazz too. 

If you just search “sourdough king cake” on google you’ll see my recipe, it’s usually the first one. 

My main tips for making this:
✨use a very active starter or throw in some instant yeast with your starter
✨make sure the dough is actually proofed before shaping it. If it’s cold in your house it will take longer. 
✨please follow directions! You can cold ferment the dough in the fridge after it doubles in size and BEFORE filling and shaping.

Fermentation is a gift from the microbes of this e Fermentation is a gift from the microbes of this earth.

When we had a food business, I could never shake the feeling that fermentation is not meant to be sold to you from a fluorescently lit grocery shelf in an endless cycle of waste. Fermentation is meant to be cultivated in your home, with your hands, with intention and love in a sustainable, grateful practice of reciprocity and nourishment. 

This is the story of how we got here. 

After so many lessons learned, our small fermentation business is now value aligned, peaceful, fulfilling, and happy.  It often seems like the gut feelings (the microbes within us) guided us in the right direction. To teach. 

You can learn for free on our blog, or you can enroll in our online courses (we extended our new year sale!) Either way, with me as your teacher, you’ll learn to adopt a holistic perspective on the microbial ecosystems that influence our food, lives, and the planet.
