Preheat oven to 425F. In a six-hole muffin tray drop a tsp of vegan butter (can sub sunflower oil) into each hole.
Place the muffin tray in the oven for 10 minutes so it gets very hot.
Meanwhile, in a small bowl add the egg replacer and water. Whisk into a smooth paste. Set aside.
Add the flour, baking powder, plant milk, egg mixture and salt to a blender. Blend on high until well combined. Alternatively, whisk by hand in a large bowl until a smooth batter forms. The mixture should be similar to a pancake batter. If too thick add a little more water.
Working quickly but carefully, remove the muffin tin from the oven and spoon or pour the batter into each hole- it should sizzle. Return the tin to the oven immediately and bake for 18-22mins or until the outsides are a deep golden brown.
