Preheat oven to 200 degrees celsius (180 if using fan-forced).
Line a 12 hole muffin tin with muffin cases.
Place the self raising flour into the TM bowl and sift by pressing Turbo 5 times.
Add the remaining ingredients and mix on Speed 5 for 5 seconds.
Scrape down the sides of the bowl and repeat for a further 5 seconds (the batter should be lumpy).
Use the spatular to fold through any add-ins you like (don't over-mix).
Spoon the mixture into the muffin cases (fill ⅔ to the top).
Bake for 20-25 minutes or until lightly golden.
Allow to cool in the baking tray for 5 minutes before transferring to a wire rack to cool completely.
