Ingredients:

  • 2 1/2 cups (300g) all-purpose flour (plain flour)
  • 1 cup (200g) granulated sugar
  • 1 tbsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1 cup (240ml) milk
  • 1/2 cup (120ml) vegetable oil (or melted unsalted butter, slightly cooled)
  • 1/4 cup (60ml) sour cream
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup (170g) semi-sweet chocolate chips (or dark chocolate, roughly chopped)

Instructions:

  1. Preheat oven to 400°F (200°C, Gas Mark 6). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
  3. In a separate bowl, whisk together the milk, oil (or melted butter), sour cream, eggs, and vanilla extract until well combined.
  4. Pour the wet ingredients into the dry ingredients and gently fold together until just combined. Be careful not to overmix; a few lumps are okay.
  5. Gently fold in the chocolate chips. Reserve a few for sprinkling on top.
  6. Fill each muffin cup about 2/3 full.
  7. Sprinkle the remaining chocolate chips on top of the muffins.
  8. Bake for 18-22 minutes, or until a toothpick inserted into the center comes out clean. Tops should be golden brown.
  9. Let the muffins cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
