Preheat the oven to 350 degrees(F).
In a large mixing bowl, sift the 1 1/4 cups of flour, then whisk in the cane sugar, baking powder, baking soda, and salt.
Make a well in the center of the dry ingredients, then pour the vegan yogurt, applesauce, olive oil, lemon zest, and lemon juice into the well. Whisk everything together until fully combined.
Toss the blueberries in the remaining teaspoon of flour and coat them the best you can. Then pour them into the batter. Fold into the batter.
Pour the batter into an 8 or 9 inch cake pan that is lined with parchment paper and smooth it out evenly.
Bake for 30-40 minutes or until a toothpick comes out clean from the center of the cake. Let cool and then serve!
