Ingredients

Scale
  • 1 1/2 cups all-purpose flour
  • 1 cup rolled oats (old-fashioned or quick-cooking)
  • 3/4 cup packed light brown sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 large egg, room temperature
  • 1/2 cup milk (dairy or non-dairy)
  • 1/2 cup plain Greek yogurt or sour cream
  • 1/4 cup melted unsalted butter or vegetable oil
  • 1 teaspoon vanilla extract
  • 1 cup fresh or frozen blueberries
  • 1 tablespoon lemon zest (optional, for brightness)

Instructions

  1. Preheat your oven to 400°F (200°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large bowl, whisk together the flour, rolled oats, brown sugar, baking powder, baking soda, and salt. This is your dry mix.
  3. In a separate medium bowl, whisk together the egg, milk, Greek yogurt (or sour cream), melted butter (or oil), and vanilla extract until combined. This is your wet mix.
  4. Pour the wet ingredients into the dry ingredients. Mix gently with a spatula until just combined. Do not overmix; a few streaks of flour are acceptable. Overmixing develops gluten, resulting in tough muffins.
  5. Gently fold in the blueberries and lemon zest, if using. If using frozen blueberries, do not thaw them first.
  6. Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds full.
  7. Bake for 18 to 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with moist crumbs attached.
  8. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For extra soft baked oatmeal muffins, use room temperature ingredients for the wet mix.
  • To keep these moist blueberry oat muffins fresh, store them in an airtight container at room temperature for up to 3 days.
  • If you want a slight crumble topping, mix 2 tablespoons of oats, 1 tablespoon of brown sugar, and 1 teaspoon of melted butter and sprinkle over the batter before baking.
