These one-bowl breakfast bars are a calm, weekday win: sourdough discard, Greek yogurt, eggs, and collagen for steady protein, plus oats, chia, flax, and blueberries for a soft, kid-friendly bite. They slice cleanly and hold up for busy mornings.
One bowl, no fuss, and slices cleanly for grab-and-go mornings.
Oats, oat flour, chia, and flax quietly thicken the batter while eggs and collagen set it into a soft, breakfast-style bar. A short 5-minute rest lets the chia and oats hydrate, so the center bakes evenly. Applesauce and a little oil keep the texture tender; blueberries add bright, juicy bites.
These work well as a breakfast-for-dinner side with eggs or yogurt bowls.
Mix the dry ingredients the night before; in the morning, whisk wet, combine, rest 5 minutes, and bake.
Swap blueberries with mini chocolate chips or diced apples.
Chill before slicing for the neatest bars. Store covered in the fridge for several days, or freeze individually for up to 2 months. See Storage Notes below for details.
Big picture: a steady, protein-forward bar built on whole grains and fiber with berries and mostly unsaturated fats. Keeping added sweetener modest and choosing extra-virgin olive oil supports a feel-good, family-friendly pattern.
Add a dollop of yogurt or cottage cheese if you want extra staying power.

Large mixing bowl
Whisk
Spatula or spoon
9 x 13 inch metal baking pan
Parchment paper (with overhang for easy lifting)
Toaster oven or conventional oven (350 F)
Cooling rack (helpful)
Offset spatula or butter knife for smoothing (optional)
Ingredient notes
Sourdough discard adds moisture and mild tang without needing fermentation time.
Greek yogurt adds protein and helps keep the bars tender.
Collagen peptides increase protein without a strong flavor, but too much can make bars firm.
Oats, chia, and flax help the bars hold together and make them more filling.
Blueberries add freshness and moisture; smaller berries distribute more evenly.
Preheat the oven
Preheat the oven to 350°F and line a 9 x 13 pan with parchment paper.
Mix the wet ingredients
Whisk the wet ingredients together until smooth.
Stir in the dry ingredients
Stir until the batter is evenly combined.
Fold in the fruit
Fold in the blueberries, then let the batter rest for 5 minutes so the chia can hydrate.
Spread in the pan
Spread the batter evenly into the prepared pan.
Bake
Bake for 24 to 28 minutes, until the center is set and the edges are lightly golden.
Cool and slice
Cool completely, then slice into 10 bars.
The batter thickens as the chia, flax, oats, and collagen absorb moisture, so a short rest before baking improves texture and structure.
Greek yogurt or cottage cheese for added, complete protein
Sliced apples, oranges, or extra berries for color and fiber
A smear of peanut, almond, or sunflower seed butter on warm bars
Coffee or unsweetened chai for grown-ups; milk for kids

Tips, variations, storage advice, and quick fixes—all in one place.
Refrigerate, covered, 4–5 days; bars slice and hold best after chilling.
Freeze individually wrapped bars up to 2 months for easy grab-and-go.
Thaw overnight in the fridge or warm gently from frozen.
Reheat lightly (toaster oven or microwave) just until warm to avoid drying.
Center underbaked: Bake 2–4 minutes longer and confirm the center no longer jiggles; ensure the 5-minute rest wasn’t skipped.
Bars seem dense: Mix just until combined after adding oat flour and collagen; overmixing compacts the crumb.
Crumbly when warm: Cool fully or chill before slicing; collagen and egg need time to set.
Excess tang: Use fresher discard or add 1 extra tablespoon maple/honey to balance acidity.
Blueberries sinking: Lightly dust berries with a spoon of oat flour before folding, and avoid big pockets of fruit.
Purple streaks: Fold frozen berries in at the very end and don’t overmix.
