Sift dry ingredients to big bowl

Add mashed bananas and 100 grams bluberries (I squirt a bit of lemon juice so the bananas don't go brown after mashing)

Incorporate rest of liquid ingredients 1 at a time

Fill pre greased muffin pan with mixture and bake for 18-20 minutes in preheated oven 170°C. They are ready when a skewer inserted comes out clean but bear in mind banana and bluberries will make muffins quite moist
