Ingredients You’ll Need:

Here’s the simple, friendly lineup for your Sourdough Blueberry Breakfast Bars. Trust me, this list respects your busy household — straightforward and budget-friendly.
- 1 cup sourdough discard (This little ingredient is the heart of your bars and a great way to reduce kitchen waste.)
- 1 ½ cups all-purpose flour (For a little extra texture, you can swap half with whole wheat flour, which adds fiber and a nutty tone.)
- ½ cup brown sugar (No worries if you don’t have brown sugar — white sugar or coconut sugar work just fine and bring their own cozy sweetness.)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon cinnamon (My family loves cinnamon for that extra hint of warmth and comfort.)
- ½ cup unsalted butter (If you want a dairy-free version, coconut oil is a perfect swap that blends well with the blueberries.)
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cups fresh or frozen blueberries (Blueberries are the star here — they offer juicy bursts and add natural sweetness. Frozen works great for year-round comfort.)
- Optional: ¼ cup chopped nuts or rolled oats on top for some extra crunch and family-approved texture.
You can find these simple ingredients right at your regular grocery store. This Sourdough Blueberry Breakfast Bars recipe proves delicious doesn’t mean expensive or complicated. If you’re running low on time, grab frozen blueberries and keep your sourdough discard ready in the fridge to whip up these bars on a whim. I like to make a double batch for quick weekday breakfasts or afternoon snacks.
One comfort hack I’ve learned? A little extra vanilla goes a long way, making the bars smell like a warm kitchen hug the moment they bake. Plus, my family gets extra comfort when I sprinkle oats on top — it adds a rustic touch they adore. If your little ones are wary of new textures, skip the nuts the first time. Remember, simple comfort with familiar flavors wins every time in busy homes.
For more wholesome and crowd-pleasing bars, my friends rave about these Halloween Oreo Brownie Bars for seasonal treats or these classic Pecan Pie Bars as easy dinnertime indulgences.
Let’s Make it Happen!
1. Preheat your oven to 350°F (175°C) and grease or line a 9×9-inch baking pan with parchment paper. This step sets you up for an easy cleanup later—one less thing to worry about!
2. In a large bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon. Mixing these dry ingredients first helps your Sourdough Blueberry Breakfast Bars bake evenly and get that perfect crumb.
3. In a separate bowl, cream the softened butter with brown sugar until smooth and slightly fluffy. Busy moms’ quick hack: If the butter’s cold, pop it in the microwave for 10-15 seconds to soften it faster.
4. Add the egg, vanilla, and sourdough discard to the butter mixture. Stir gently to combine. This mix gives your bars that unique tang and tender crumb sourdough baking is known for.
5. Fold in the dry ingredients until just combined. Don’t overmix! Overworking the batter can make your breakfast bars dense, and we want fluffy comfort here.
6. Gently fold in blueberries, saving a handful for sprinkling on top if you want them extra pretty. Your kitchen should start smelling warm and just like comfort now.
7. Pour the batter into the prepared pan and spread evenly. Sprinkle those reserved blueberries and optional oats or nuts on top for a family-approved finishing touch.
8. Bake for about 35-40 minutes. The bars should be golden brown, and a toothpick inserted in the center comes out mostly clean (a few moist crumbs are good).
If your Sourdough Blueberry Breakfast Bars look a bit soft when you pull them from the oven, don’t worry — they’ll set up as they cool. For a time-saver in busy kitchens, I often prepare the night before so the bars are ready when breakfast chaos begins. While your bars bake, it’s the perfect moment to prep tomorrow’s school lunches or enjoy a peaceful cup of coffee.
Over time, I learned my family loved these bars best cooled completely and kept in an airtight container. Little bonus: leftovers taste excellent cold or warmed up with a smear of nut butter.
