Sourdough granola bars are the perfect snack. They are easy to pack around and full of sustaining energy. They are a delicious breakfast-on-the-go, school lunch treat or a homemade energy bar. Best of all, they can be made gluten free, sugar free or vegan!
I like to preferment all of my grains. However, the sourdough starter in this recipe is only a suggestion. The recipe can also be made with yogurt or buttermilk to soak and ferment the oatmeal.
Here’s why these granola bars are better because of a little fermentation.
- Fermentation adds a delicious sourdough flavour to these granola bars.
- Soaked and fermented grains are easier digest, so this granola bar won’t leave you feeling sluggish from the carb overload.
- Pre-fermentation also eliminates the need for additional flour or sweetener. The lactic bacteria will break down the rolled oats before baking.
Granola Bar Flavours
The best part about homemade baked goods is that they are a delicious way to experiment with flavour. Sourdough granola bars are perfect for so many flavour options. Here are a few of my favourites:
- Blueberry Almond: This classic granola bar is perfect for breakfasts on the go. Use 1/2 cup of almonds, 1/4 cup of dried blueberries and 1/4 cup of shredded coconut.
- Salty Peanut: Use 1 cup of salty peanuts for a salty (not sweet) granola bar. Or use only 1/2 cup of peanuts with 1/2 cup of chocolate chips.
- Immune Boosting: This school-friendly and beautiful granola bar is packed full of zinc, iron and antioxidants. Use a 1/2 cup of goji berries and 1/2 cup of pumpkin seeds.
- Chocolate Pecan: Turn your granola bars into a sweet treat by adding 1/2 cup of chopped pecans and 1/2 cup of dark chocolate chips.
- Tropical Punch: This granola bar combines the sweetness of tropical fruit with high protein cashews for a healthy energy bar that will help you go the distance. Use 1/2 cup of mixed tropical fruit (mango, pineapple and papaya) with 1/4 cup of cashews and 1/4 cup of shredded coconut.

- Prep Time: 15 minutes
- Cook Time: 50 minutes
- Total Time: 1 hour 5 minutes
- Yield: 12 bars 1x
- Category: Snack
- Method: Sourdough
- Cuisine: Healthy
- 1 1/2 cups of rolled oats (quick or regular)
- 1/2 cup sourdough starter (see notes for yogurt alternative)
- 2 eggs (see notes for vegan flax eggs option)
- 1/4 cup ground dates
- 1 tsp vanilla
- 1/2 tsp salt
- 1 cup mixed nuts, seeds and dried fruit
- Mix rolled oats and the sourdough starter in a glass bowl. It will be quite dry. However, cover and leave it to soak or ferment for at least 30 minutes and up to 12 hours.
- Beat in the eggs, ground dates, vanilla and salt.
- Mix in 1 cup of added nuts, seeds, dried fruit or chocolate chips. See the section above for 5 delicious flavour options.
- Grease a 9″ x 9″ baking pan (or other 10 cup baking pan). Spread the granola bar mixture in the pan, and press so that it is firmly packed into the bottom of the pan.
- Bake at 300 F (150 C) for 50-60 min, until firm and browning around the edges.
- Remove from the oven and slice right away. Then allow the granola bars to cool before removing them from the pan.
- Though the recipe is written for a sourdough starter, you could also use a gluten free sourdough starter or replace the sourdough starter with yogurt or buttermilk. It will be a bit more liquidy, but the oats will absorb the extra liquid and result in a softer granola bar.
- The eggs in this recipe are used as a binder and are mostly necessary for gluten free granola bars. However, flax is a really great binder as well. To replace the eggs with flax, use 2 tbsp of ground flax mixed in a 1/4 cup of water. Leave it to sit and gel for 5 minutes, then stir into the granola bars.
- Date sugar (affiliate link) is my usual sweetener of choice. It is high in fiber, vitamins and minerals. However, it is not very sweet. To make a sweeter granola bar replace the ground dates with brown sugar, rice syrup or honey.
