If your mornings feel rushed and breakfast usually gets skipped or swapped for something you regret by 10am, these high fiber oat bran muffins with blueberries are about to change your routine. They come together in one bowl, bake in under 20 minutes, and genuinely keep you full until lunch. That is not a small thing. Most muffins you grab from a coffee shop are basically dessert in disguise, loaded with refined flour, sugar, and very little nutrition. These are built differently, from the inside out.
The star ingredient here is oat bran, which is the outer layer of the oat grain and one of the richest sources of soluble fiber you can add to baked goods. Soluble fiber, particularly beta-glucan found in oat bran, has been shown to support healthy cholesterol levels and slow the digestion of carbohydrates, which means more stable energy and fewer mid-morning crashes. Alongside the oat bran, this recipe uses a small amount of whole wheat flour to give the muffins just enough structure without making them dense or heavy. Greek yogurt is stirred into the batter for a quiet protein boost and a subtle tang that balances the sweetness of the blueberries beautifully. Two eggs add further protein and help the muffins rise properly without needing a mountain of baking powder.
The sweetness here comes from a modest amount of pure maple syrup and the natural sugars in the blueberries themselves. There is no refined white sugar in this recipe at all. Fresh or frozen blueberries both work wonderfully. Frozen ones actually tend to distribute more evenly through the batter because they are firmer and less likely to crush when you fold them in. A teaspoon of cinnamon and a pinch of nutmeg warm everything up and make the kitchen smell incredible while these bake. Vanilla extract rounds out the flavour without adding any extra sugar. One thing worth noting: do not overmix the batter. A lumpy batter is a good batter here. Overmixing develops the gluten in the flour and makes muffins tough, and nobody wants a tough muffin.
Each muffin comes in at around 165 calories, with 7 grams of fiber and 8 grams of protein. That combination is genuinely hard to find in a baked good, and it makes these muffins a smart option for anyone managing blood sugar, working on digestive health, or simply trying to eat more whole foods in the morning without spending a lot of time in the kitchen. They freeze brilliantly, so baking a batch on Sunday means you have breakfast sorted for the whole week. Pull one out the night before and let it thaw on the counter, or give it 30 seconds in the microwave and top it with a little almond butter. That right there is a breakfast worth waking up for.
Ingredients
- 1.5 cups oat bran (not rolled oats, use actual oat bran)
- 0.8 cup whole wheat flour (spooned and levelled)
- 1.5 tsp baking powder
- 0.5 tsp baking soda
- 1 tsp ground cinnamon
- 0.3 tsp ground nutmeg
- 0.3 tsp fine sea salt
- 2 large eggs (room temperature)
- 0.8 cup plain low-fat Greek yogurt (full-fat also works)
- 0.5 cup unsweetened almond milk (or any milk of choice)
- 3 tbsp pure maple syrup (use grade A for best flavour)
- 2 tbsp coconut oil (melted and cooled)
- 1 tsp pure vanilla extract
- 1 tsp apple cider vinegar (activates the baking soda)
- 1.3 cups blueberries (fresh or frozen, do not thaw if frozen)
- 1 tbsp oat bran (extra, for topping)
Instructions
- 1
Preheat your oven to 375°F (190°C). Line a standard 12-cup muffin tin with paper liners or lightly grease each cup with a small amount of coconut oil.
Paper liners make cleanup much easier and help the muffins release cleanly.

In a large mixing bowl, whisk together the oat bran, whole wheat flour, baking powder, baking soda, cinnamon, nutmeg, and sea salt until evenly combined.
- 3
In a separate medium bowl, whisk the eggs until lightly beaten. Add the Greek yogurt, almond milk, maple syrup, melted coconut oil, vanilla extract, and apple cider vinegar. Whisk until smooth and fully combined.
Make sure the coconut oil is cooled before adding it or it can scramble the eggs.
- 4
Pour the wet ingredients into the dry ingredients and stir with a wooden spoon or spatula until just combined. Stop as soon as you no longer see dry streaks. The batter will look a little lumpy and that is completely fine.
Overmixing is the most common muffin mistake. A lumpy batter gives you a tender crumb.
- 5
Gently fold in the blueberries using a spatula, turning the batter over just 3 or 4 times. If using frozen blueberries, work quickly so they do not bleed too much colour into the batter.
Tossing frozen blueberries in a teaspoon of flour before adding them helps them stay suspended in the batter.
- 6
Divide the batter evenly among the 12 muffin cups, filling each about three-quarters full. Sprinkle a small pinch of the reserved oat bran over the top of each muffin.
- 7
Bake for 17 to 19 minutes, until the tops are lightly golden and a toothpick inserted into the centre of a muffin comes out clean or with just a few moist crumbs.
Start checking at the 17-minute mark since oven temperatures vary. Do not overbake or they will dry out.
- 8
Remove the tin from the oven and allow the muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Letting them sit in the tin briefly helps the structure set so they do not collapse when you lift them out.

Pro Tips
- ✓
Use oat bran specifically, not oatmeal or rolled oats. The texture and fiber content are quite different.
- ✓
Do not thaw frozen blueberries before folding them in. This prevents the batter from turning purple and keeps the berries intact.
- ✓
Room temperature eggs and yogurt blend into the batter more smoothly than cold ingredients straight from the fridge.
- ✓
Spoon and level your flour rather than scooping directly from the bag to avoid packing in too much flour.
- ✓
These muffins taste even better the next day once the oat bran has had time to absorb the moisture and the flavours meld together.
- ✓
For extra protein, serve alongside a couple of scrambled eggs or with a smear of almond butter on top.
Frequently Asked Questions
Variations
- •
Lemon Blueberry Oat Bran Muffins
Add the zest of one large lemon and 1 tablespoon of fresh lemon juice to the wet ingredients. The brightness of lemon pairs brilliantly with blueberries and adds a fresh lift to the muffins.
- •
Mixed Berry High Fiber Muffins
Swap half the blueberries for raspberries or diced strawberries. The combination of berries adds variety in flavour and a boost of vitamin C.
- •
Banana Blueberry Oat Bran Muffins
Replace the maple syrup with one large ripe mashed banana for a naturally sweeter, lower-glycemic option with extra potassium and fibre.
- •
Protein-Boosted Muffins
Stir one scoop of unflavoured or vanilla protein powder into the dry ingredients, reducing the oat bran by 2 tablespoons to keep the texture balanced. This can bring each muffin up to around 11 to 12 grams of protein.
Substitutions
- •Whole wheat flour → Certified gluten free 1:1 baking flour (Use an equal amount for a gluten free version. The texture will be slightly lighter.)
- •Greek yogurt → Plain unsweetened coconut yogurt (Works well for a dairy free version. Choose a thick style for best results.)
- •Coconut oil → Light olive oil or melted unsalted butter (Any neutral-flavoured oil works here. Butter adds a slightly richer taste.)
- •Maple syrup → Honey or mashed ripe banana (Honey provides a floral sweetness. One mashed banana adds fibre and natural sweetness with no added sugar.)
- •Almond milk → Oat milk, soy milk, or regular low-fat cow's milk (Any milk works in an equal amount. Soy milk adds a small amount of extra protein.)
- •Eggs → 2 flax eggs (2 tbsp ground flaxseed mixed with 6 tbsp water, rested for 5 minutes) (For a vegan version. The muffins will be slightly denser but still hold together well.)
🧊 Storage
Store cooled muffins in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze individually wrapped muffins in a zip-lock bag or airtight container for up to 3 months. Thaw overnight on the counter or microwave from frozen for 30 to 45 seconds.
📅 Make Ahead
You can mix the dry and wet ingredients separately the night before and store them covered in the fridge. Combine them and bake fresh in the morning for the best texture. Alternatively, bake a full batch on the weekend and freeze them for weekday breakfasts.
