Preheat oven to 180C. Add muffins papers to a muffin tray. (makes 12 large muffins). Original recipe uses a 20cm cake tin - our family manages the portions better as muffins.
2. Place orange and butter into mixing bowl and mix 7 sec/speed 8. My family likes a smoother orange cake (less chunks) so I scrape down the bowl sides and mix for another 15 sec/speed 8.
3. Add remaining ingredients and combine 20 sec//speed 4. (Option: I chose to mix it longer in regular direction for 30 secs/speed 8 (or more if you prefer) to give a lighter consistency. You can push the spatula into the lid to assist the mixing process if necessary).
4. Spoon large dollops into muffin cases and bake for 35-40 minutes or until skewer comes out clean. Feel free to lick the bowl!
