Ingredients

Muffins

  • ¼ cup melted butter (57g)
  • ¼ cup canola oil may substitute vegetable oil (60ml)
  • 3/4 cup sugar (150g)
  • ¼ cup brown sugar tightly packed (50g)
  • 1 large egg + 1 egg white room temperature preferred
  • 1 1/2 teaspoon vanilla extract
  • 1/2 cup buttermilk room temperature preferred (120ml)
  • 1 3/4 cup all-purpose flour (220g)
  • 2 teaspoons baking powder
  • 2 teaspoons corn starch (cornflour in UK)
  • ½ teaspoon cinnamon
  • ½ teaspoon salt

Streusel topping:

  • 1 1/4 cup all-purpose flour (156g)
  • 1/2 cup light brown sugar tightly packed (100g)
  • 1/3 cup sugar (66g)
  • 3/4 teaspoon ground cinnamon
  • 6 Tablespoons butter melted (85g)

Instructions

  • Preheat oven to 375F (190C) and line a 12-count muffin tin with paper liners. Set aside.
  • Combine your melted butter and canola oil in a large bowl. Stir well.
  • Add sugar and stir to combine.
  • Add egg, egg white, and vanilla extract. Stir very well, until all ingredients are thoroughly combined.  Add buttermilk and stir.
  • In a separate, medium-sized bowl, whisk together flour, baking powder, corn starch, cinnamon and salt.
  • Using a spatula, gently fold the dry ingredients into the wet, taking care not to over-mix the batter (which will make your muffins dense and tougher).
  • Evenly divide the batter into prepared muffin tin, filling each liner about 2/3 of the way full. Set aside and prepare your streusel topping.

Streusel

  • Prepare your streusel by whisking together flour, sugars and cinnamon.
  • Pour the melted butter into the mixture and, using a fork, stir until crumbles form. 
  • Using your hands, evenly divide streusel over muffin batter, piling the streusel over the batter and gently pressing the topping into the batter.
  • Bake on 375F for 22-25 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  • Allow to cool before serving.
