Preheat the oven to 180ºC
Grease a 12-cup muffin tray with vegan butter or coconut oil.
Mix the flour, baking powder, bicarb, salt, and sugar in one bowl.
In another bowl, beat the aquafaba, flaxseed, oil, and soy yoghurt together.
Add the wet mixture to the dry mixture, and mix until blended. Be careful not to overmix!
Stir in the blueberries.
Spoon the mixture into the muffin tray, and place in the middle of your preheated oven.
It should be done about about 20-30 minutes.
Remove and place the tray on a wire rack, and leave until it’s cool enough to touch, before removing the muffins.
