  • 150 g plain flour
  • 1 tsp baking powder
  • ¼ tsp baking soda
  • ¼ tsp fine sea salt
  • 1 large egg, room temperature
  • 100 g unpasteurised honey
  • 60 ml buttermilk, room temperature
  • 60 ml rapeseed oil
  • 1 tbsp lemon zest (about 1 medium lemon)
  • ½ tsp pure vanilla extract
  • 100 g fresh blueberries


  1. Preheat the oven to 190ºC (375ºF) and line a regular sized muffin tin with 6 silicone or paper liners.
  2. In a large bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. Set aside.
  3. Add the egg, honey, buttermilk, oil, lemon zest, and vanilla to a medium bowl or measuring cup. Whisk together well until emulsified.
  4. Make a well in the dry ingredients and pour the wet ingredients into it. Gently fold everything together 3-4 times, then add the blueberries. Keep folding gently just until the berries are dispersed and the flour disappears. Do not over mix the batter; it’s okay if it’s a bit lumpy.
  5. Divide the mixture evenly between the 6 cups. The batter should just reach the top of each cavity. Top with a few additional blueberries if desired.
  6. Bake the muffins for 16-19 minutes or until a toothpick inserted comes out clean or with just a few crumbs attached.
  7. Allow the muffins to cool in the tray for 5 minutes, then remove them to a wire rack to finish cooling completely.
