For the muffins

  • 1 and 1/2 cups all-purpose flour
  • 3/4 cup granulated sugar
  • 1/2 teaspoon salt
  • 2 teaspoons baking powder
  • 1/3 cup vegetable oil or melted butter
  • 1 large egg
  • 1/3 – 1/2 cup milk (start with 1/3 cup and add more if needed)
  • 1 and 1/2 teaspoons vanilla extract
  • 1 cup fresh or frozen blueberries (if using frozen, do not thaw)


For the oat crumble topping

  • 1/2 cup old-fashioned oats
  • 1/4 cup all-purpose flour
  • 1/4 cup brown sugar
  • 1/4 teaspoon ground cinnamon
  • 2 tablespoons cold butter, diced



  1. Preheat your oven to 200°C (400°F). Grease or line a muffin tin with paper liners.
  2. In a large mixing bowl, whisk together the flour, sugar, salt, and baking powder.
  3. In a separate bowl, whisk together the vegetable oil or melted butter, egg, milk, and vanilla extract until well combined.
  4. Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix.
  5. Gently fold in the blueberries until evenly distributed throughout the batter.
  6. Spoon the batter into the prepared muffin tin, filling each cup about 2/3 to 3/4 full.
  7. In a small bowl, combine the oats, flour, brown sugar, and cinnamon for the crumble topping. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
  8. Sprinkle the oat crumble topping evenly over the muffin batter in each cup.
  9. Bake the muffins in the preheated oven for 18-22 minutes, or until the tops are golden brown and a toothpick inserted into the center of a muffin comes out clean.
  10. Remove the muffins from the oven and allow them to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
  11. Enjoy your homemade blueberry muffins with oat crumble topping warm or at room temperature. They’re best eaten the same day they’re baked, but you can store any leftovers in an airtight container at room temperature for up to 2 days.
