Method
- Heat the oven to 375°F (190°C). Line or grease twelve standard muffin cups. In a bowl, whisk milk, yogurt, eggs, oil and vanilla. Stir in oat bran and flax, then leave for 10 minutes while preparing the dry ingredients.
- In a second bowl, whisk flour, sugar, baking powder, baking soda, cinnamon and salt. Add the soaked mixture and fold until only a few flour streaks remain. Fold in blueberries gently, stopping as soon as dry pockets disappear. Do not beat the batter smooth.
- Divide the batter evenly between the twelve cups, keeping it below the rims. Bake for roughly 22–27 minutes. Check a middle muffin: the top should spring back lightly and a skewer inserted away from a berry should show crumbs rather than uncooked batter. Continue briefly if necessary.
- Leave muffins in the pan for 5 minutes, then move them to a rack for at least another 5 minutes. Allow them to cool completely before sealing a container. A warm muffin enclosed too soon releases steam that wets its surface.
Notes
Recipe development note: This formulation has not been kitchen-tested. Cooking and preparation times are estimates; follow the stated texture checks and product instructions.
If the muffins are dry, first check how the flour was measured and whether they baked beyond the texture check. Adding more berries will not repair an overly dry flour-to-liquid ratio. If the tops sink, check that the center was cooked before removal.
A lumpy batter is expected. Repeated stirring develops the flour and can leave the muffins tough. If the mixture seems unusually rigid before the berries go in, add milk one tablespoon at a time, only until it can be scooped.
Cool fully and keep in a covered container for up to 2 days at a cool room temperature. Refrigerate for up to 4 days in hot or humid conditions. Freeze individually wrapped muffins for up to 2 months. Thaw covered in the refrigerator and warm briefly before eating.
