To make this Sourdough Blueberry Breakfast Bars, here’s what you’ll want to gather:

A quick shopping note: Most of these ingredients come from everyday kitchen staples, so this sourdough blueberry breakfast bars recipe is budget-friendly and easy to pull together. I always keep a jar of rolled oats and frozen blueberries handy just for days when I want to whip up these easy sourdough bars.

Before you start, pre-measure your ingredients to save time. If your sourdough starter lives in the fridge, bring it to room temperature for best results. The oats will soak up moisture beautifully, so no need for extra liquid. This simple ingredient list is why this Sourdough Blueberry Breakfast Bars has stayed in my rotation so faithfully.

1. Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper for easy removal. This step ensures your sourdough blueberry breakfast bars won’t stick and keeps cleanup simple.

2. Mix the dry ingredients. In a medium bowl, combine the rolled oats, whole wheat flour, brown sugar, baking soda, and cinnamon. Stir them gently to blend. Using dry ingredients first helps spread the flavors evenly throughout the bars.

3. Combine wet ingredients next. In another bowl, whisk together the sourdough starter, melted coconut oil (or butter), and vanilla extract. Your kitchen will start to smell subtly sweet and inviting already.

4. Gently fold the wet ingredients into the dry mix. This is where a gentle hand makes all the difference with your sourdough blueberry breakfast bars. The batter will look thick and hearty but soft enough to spread.

5. Carefully fold in the blueberries. Whether fresh or frozen, be gentle here to keep the berries intact and evenly distributed. If you spot any clumps, a quick stir will fix it.

6. Spread the batter evenly in your prepared pan. The surface should be smooth with your spatula, but don’t overwork it—that keeps these blueberry oat bars tender. Pressing down gently helps the bars hold together well.

7. Bake for 30-35 minutes. From start to finish, this Sourdough Blueberry Breakfast Bars takes about 45 minutes including prep. When done, the top should be golden with a slight firmness. If you press lightly, it feels springy but sets nicely. Your kitchen will smell heavenly right about now.

8. Cool completely in the pan. This step is crucial for clean-cut bars that hold their shape. It’s a perfect time for a cup of tea or tidying up.

9. Cut into bars and enjoy! Whether you slice them into squares for a quick grab-and-go or smaller pieces for sharing, these bars keep beautifully.

If your sourdough blueberry breakfast bars look a little cracked on top, that’s a great sign—they’re baking nicely. Don’t worry if a few berries burst during baking; that’s just added flavor and color.

For anyone pressed for time, you can prepare the mix the night before and bake fresh in the morning.

I love serving these Sourdough Blueberry Breakfast Bars warm with a little pat of butter melting on top. They’re great alongside a hot cup of coffee or herbal tea. The mild tanginess from the sourdough pairs beautifully with the sweet blueberries, creating a perfect balance for a healthy breakfast bars option.

These bars also make a fantastic snack for school lunches or a quick pick-me-up during busy afternoons. For a simple decoration, I sometimes drizzle a little honey or sprinkle sliced almonds on top right after baking—not necessary, but a lovely touch.

If you want to try something different, these blueberry breakfast bars recipe variations work well with other berries or even chopped apples and cinnamon. I’ve even swapped in walnuts for a bit of crunch. Seasonally, adding a sprinkle of nutmeg in fall feels just right.

Friends and family often request these bars for weekend brunches or casual get-togethers. If you enjoy this, you might love my twist on peanut butter banana oat bars — another reliable, healthy breakfast bars recipe.

Leftovers? No problem. These bars keep well in an airtight container for up to four days, and they freeze beautifully too. I pop a couple in my kids’ lunchboxes, and they love them just as much cold as warm.

Can I make this Sourdough Blueberry Breakfast Bars ahead of time?
Absolutely! I recommend baking the day before and storing in an airtight container. Warm slightly before serving to get that fresh-baked feel.

What’s a good substitute for whole wheat flour in this recipe?
All-purpose flour is the easiest swap and still delivers great texture. For gluten-free options, a blend designed for baking works if you want to try.

Can I use frozen blueberries?
Definitely. Just fold them in frozen to avoid bleeding too much juice early on. Frozen blueberries keep this recipe affordable and year-round.

How do I adjust the recipe for different pan sizes?
If you use a larger pan, your bars will be thinner and bake faster, so check around 20-25 minutes. For smaller pans, bake a little longer. Keeping an eye on the color and firmness is your guide.

Is there a way to add more protein?
Yes! I’ve seen readers add collagen powder or nut butter. There’s also a great take on a Sourdough Breakfast Bars Recipe with Collagen Powder if you want to up that protein.

Can I substitute the oats with another grain?
Oats are key for the texture, but I’ve tried quinoa flakes and they offer a different chewiness, still tasty but different.

What if my starter is less active?
This recipe is forgiving since the baking soda helps with rise. Just make sure your sourdough starter isn’t too sour or overly fermented.
