Bran Muffins with Blueberries and Flaxseed (High-Protein, Low-Sugar)
There is something deeply satisfying about pulling a tray of warm, golden muffins out of the oven first thing in the morning. These bran muffins with blueberries and flaxseed are the kind of breakfast that actually keeps you going until lunch, not just for forty-five minutes. They are dense in the best possible way, loaded with fibre, and naturally sweetened so you never feel that mid-morning sugar crash creeping in. Think of them as your new weekday staple, the muffin you bake on Sunday and reach for every single morning after that.
The secret to making these genuinely healthier than your average bakery bran muffin is layering multiple sources of fibre and protein rather than relying on white flour and brown sugar. Oat bran forms the backbone here, bringing soluble fibre that absorbs liquid and keeps you full. Ground flaxseed adds omega-3 fatty acids and a subtle nuttiness that pairs beautifully with the burst of fresh blueberries in every bite. Whole wheat flour keeps the structure light enough to avoid a brick-like texture, while rolled oats add a little chew. Greek yogurt is the real hero for protein, replacing much of the oil you would normally find in a traditional recipe and contributing a slight tang that balances the sweetness of the berries perfectly.
Sweetness comes entirely from ripe banana and a small amount of pure maple syrup, so there is no refined sugar anywhere in the batter. Ripe banana does double duty here: it sweetens, it moistens, and it binds the batter alongside two eggs. A generous handful of fresh or frozen blueberries goes in at the very end, folded in gently so they stay whole and juicy. When they burst during baking, they create little pockets of colour and flavour throughout the muffin. Ground cinnamon and a hint of vanilla round everything out, making these taste far more indulgent than their nutrition label would suggest.
At around 185 calories per muffin with 9 grams of protein and 6 grams of fibre, these fit comfortably into a balanced morning without any calorie counting stress. They are brilliant for meal prep: bake a batch at the start of the week and breakfast is sorted for five days straight. Kids love them too, especially if you use extra blueberries. You can swap fresh for frozen year round, which makes this recipe genuinely accessible no matter the season. Once you have made these a couple of times, you will find yourself adjusting them to your taste, adding lemon zest, stirring in a handful of chopped walnuts, or swapping the blueberries for raspberries when you fancy a change.
Ingredients
- 1 cup oat bran (not instant oat bran)
- 3 cup whole wheat flour
- 1 cup rolled oats (old-fashioned, not quick oats)
- 1 cup ground flaxseed (also called flaxseed meal)
- 1 tsp baking powder
- 1 tsp baking soda
- 1 tsp ground cinnamon
- 1 tsp fine sea salt
- 2 large eggs (room temperature)
- 3 cup plain Greek yogurt (full-fat or 2%, not non-fat)
- 1 medium ripe banana (well-mashed, about 1/3 cup)
- 3 tbsp pure maple syrup (grade A or B)
- 2 tbsp coconut oil (melted and cooled)
- 1 tsp pure vanilla extract
- 1 cup unsweetened almond milk (or any non-dairy milk)
- 1 cups fresh or frozen blueberries (do not thaw if using frozen)
Instructions
- 1
Preheat your oven to 190°C (375°F). Line a standard 12-cup muffin tin with paper liners or lightly grease each cup with a little coconut oil spray.
Paper liners make clean-up much easier and help the muffins hold their shape while cooling.

In a large mixing bowl, whisk together the oat bran, whole wheat flour, rolled oats, ground flaxseed, baking powder, baking soda, cinnamon and sea salt until evenly combined. Make a well in the centre of the dry ingredients and set aside.
- 3
In a separate medium bowl, whisk the eggs until lightly beaten. Add the Greek yogurt, mashed banana, maple syrup, melted coconut oil, vanilla extract and almond milk. Whisk until everything is smooth and fully combined.
Make sure your coconut oil is fully cooled before adding it to the yogurt mixture, otherwise it can start to solidify when it hits the cold yogurt.
- 4
Pour the wet ingredients into the well of the dry ingredients. Using a spatula or wooden spoon, fold gently until just combined. Stop mixing as soon as you no longer see streaks of dry flour. The batter will look a little thick and lumpy, which is exactly right.
Overmixing muffin batter develops gluten and leads to tough, dense muffins. A few lumps are your friend here.
- 5
Add the blueberries to the batter. Fold them in with three or four gentle strokes of the spatula, being careful not to crush them. If using frozen berries, work quickly so the batter does not turn purple.
Tossing the blueberries in a teaspoon of flour before adding them can help prevent them from sinking to the bottom.
- 6
Divide the batter evenly among the prepared muffin cups, filling each one about three-quarters full. The batter is thick enough that a small ice cream scoop works brilliantly for portioning.
- 7
Bake in the preheated oven for 20 to 22 minutes, until the tops are golden brown and a toothpick inserted into the centre of a muffin comes out clean or with just a couple of moist crumbs attached.
Start checking at 20 minutes. Every oven varies slightly and overbaked bran muffins can turn dry quickly.
- 8
Remove the tin from the oven and let the muffins cool in the pan for 5 minutes. Then transfer them to a wire rack to cool completely. They are wonderful warm but actually taste even better the next day once the flavours have settled.

Pro Tips
- ✓
Do not skip the resting period after baking. Bran muffins firm up and develop more flavour as they cool.
- ✓
Ripe bananas with plenty of brown spots give the best natural sweetness. An underripe banana will make the muffins taste starchy.
- ✓
Ground flaxseed (flaxseed meal) is easier for your body to absorb than whole flaxseeds. Buy it pre-ground or grind whole flaxseeds yourself in a coffee grinder.
- ✓
If your batter looks very thick, add an extra tablespoon of almond milk to loosen it slightly. The oat bran absorbs a lot of liquid.
- ✓
For extra-domed muffin tops, start the oven at 210°C (410°F) for the first 5 minutes then reduce to 190°C (375°F) for the remaining baking time.
- ✓
Sprinkle a pinch of rolled oats on top of each muffin before baking for a bakery-style finish.
Frequently Asked Questions
Variations
- •
Lemon Blueberry Bran Muffins
Add the zest of one large lemon to the wet ingredients and replace the vanilla extract with lemon extract. The brightness of the lemon pairs beautifully with the blueberries and cuts through the earthiness of the oat bran.
- •
Double Berry Bran Muffins
Replace half the blueberries with fresh or frozen raspberries. The combination of the two berries creates a lovely tart-sweet contrast and keeps things interesting if you are making these weekly.
- •
Walnut and Blueberry Bran Muffins
Fold in 1/4 cup of roughly chopped walnuts along with the blueberries for added healthy fats, crunch and an extra boost of omega-3 fatty acids. This also increases the protein content slightly per serving.
- •
Pumpkin Spice Bran Muffins
Replace the mashed banana with 1/3 cup of pure pumpkin puree and swap the cinnamon for 1 1/2 teaspoons of pumpkin spice blend. Use dried cranberries instead of blueberries for an autumn-inspired version.
Substitutions
- •Greek yogurt → dairy-free coconut yogurt (Use unsweetened coconut yogurt for a fully dairy-free version. The muffins will be slightly less protein-dense but still moist and flavourful.)
- •Whole wheat flour → spelt flour (Spelt flour has a slightly nuttier flavour and similar nutritional profile to whole wheat. Use a 1:1 swap with no other adjustments needed.)
- •Coconut oil → light olive oil (Light olive oil has a neutral flavour and works perfectly as a 1:1 substitute. It keeps the muffins moist without any coconut flavour.)
- •Maple syrup → raw honey (Raw honey works as a direct swap at the same quantity. It adds a floral sweetness that complements the blueberries well. Note this makes the recipe non-vegan.)
- •Almond milk → oat milk or regular dairy milk (Any milk works here. Oat milk adds a subtle sweetness. Dairy milk increases the protein content slightly.)
- •Fresh blueberries → frozen blueberries (Add directly from frozen without thawing to prevent excess moisture from bleeding into the batter.)
🧊 Storage
Store fully cooled muffins in an airtight container at room temperature for up to 2 days. Refrigerate for up to 5 days, placing a sheet of paper towel in the container to absorb any excess moisture from the blueberries. To freeze, wrap individual muffins in cling film and place in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge or microwave from frozen for 60 to 90 seconds.
📅 Make Ahead
These muffins are ideal for meal prep. Bake a full batch on Sunday and breakfast is covered for the entire week. The flavour and texture actually improve after the first day as the oat bran and flaxseed soften and the spices deepen. You can also mix the dry ingredients and wet ingredients separately the night before, keep them in the fridge, and combine and bake the following morning for truly fresh muffins with minimal effort.
