Add yeast and sugar to warm water. Stir and set aside until frothy.
Add remaining dry ingredients of flour, salt and baking powder to a large mixing bowl and whisk to combine.
Once the yeast mixture is foaming, add the oil and yoghurt. Stir to combine then add to dry ingredients.
Mix the wet and dry ingredients to form a sticky dough. Turn out onto a floured surface and gently knead a few times, just enough to bring the mixture together.
Once the dough has formed a loose ball, pop into a bowl and cover with a damp towel or eco-friendly wrap. Pop into a warm place for around 2 hours.
After the dough has rested and risen, knead again gently and add some extra flour if the dough is too sticky. Divide into six even pieces.
Lightly knead each of the six pieces into a ball and pop onto a baking tray. Cover with a damp towel or that eco-friendly wrap and allow to rest again for a further 10 minutes.
Heat your frying pan (cast iron, if you have it). Shape the dough ball into a rough Naan shape. If you feel fancy you can roll the ball into a circular shape with a rolling pin. I prefer less effort and a more rustic shape so just use my hands.
Cook the Naan until the edges start to bubble, flip and cook the other side to a dark brown colour.
Once cooked, brush with melted dairy-free butter and salt flakes.
