Step 1

Preheat the oven to 375F and line a muffin tin with liners.

Step 2

Mix together the flour, baking powder, baking soda, sugar, cinnamon and nutmeg until just combined.

Step 3

Then add the oil, melted butter, milk, eggs, vanilla and yogurt. Mix well until there are no big lumps of flour.

Step 4

Then, fold in the blueberries.

Step 5

Scoop the batter into the liners and fill ¾ of the way. Sprinkle on a bit of sugar if you desire.

Step 6

Bake for 17-20 minutes, or until the muffins are just golden brown at the edges and spring back when you press on the center.

Step 7

Cool in the tin for 5 minutes before removing to a wire rack to cool completely.
