In a large-size bowl, add all the dry ingredients and mix until combined. Add all of the wet ingredients except the blueberries and mix until the batter is combined and smooth.
Pour the cake batter into the lined baking tin. Scatter blueberries over and press them into the cake batter.
Bake the cake for around 25 minutes or until a skewer can be inserted into the middle of the cake and it comes out clean. Allow the cake to rest in the cake tin.
