Healthy Whole Wheat Cinnamon Blueberry Muffins are a moist, sweet, and cinnamony start to a beautiful day.
Preheat the oven to 400 degrees. Grease the bottoms of a 12-cup muffin tin, or line with paper cups. Set aside.
Whisk together the flours, sugar, baking powder, cinnamon, and salt. Make a well in the center and add milk, oil, and beaten egg. Stir until just combined. The batter should be lumpy. Fold in the blueberries.
Divide batter evenly (I use a cookie scoop) among the muffin tins. Sprinkle with brown sugar if desired. Bake for 18-20 minutes or until golden brown. Immediately remove muffins from the pan to cool.
