Preheat your oven to 180c. Lightly spray your muffin pan or use muffin liners.
Add all your dry ingredients into a bowl and mix lightly with a whisk.
Add in the oil, vanilla essence, egg and milk.
Whisk until just combined.
Add in your strawberries and gently fold through.
Fill each muffin hole about 3/4 way up the top.
Place in the oven for 13-15 mins or until lightly golden and a skewer comes out clean.
Let cool in the muffin pan.
Once cooled gently remove, you may need the help of a knife to run around the sides.
