Pop the dry ingredients (excluding the raisins) in a large bowl and give them a good whisk to combine, you can use a fork if you don’t have a whisk
Add the raisins to the dry ingredients
Peel the banana and the orange, core the apple but you can leave the skin on the apple
Pop the fruit, spinach, and the rest of the wet ingredients in a blender or food processor, blitz until you get a nice smooth green smoothie
Pour the smoothie into dry ingredients and mix together, mix until just combined
Portion into a greased muffin tin, I find the mix makes 12 standard-sized muffins
Bake at 180 degrees Celsius until cooked, you should be able to press the top of the muffin and it will spring back
Cool in the muffin tray for 5-10 minutes, remove from the muffin tray and leave on a cooling rack
Store in an airtight container for 48 hours
Or Freeze for up to 3 months
