Pre-heat the oven to 350°F.
In a medium bowl, mix all the ingredients together and spoon into a muffin tray lined with paper muffin liners.
Place in the pre-heated oven and bake for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Please note, these muffins do take a little longer to bake than other muffins - this is because of the water added to the batter.
