Pre-heat oven to 350 Degrees F. In a bowl miz all the dry ingredients (Flour, Sugar, Baking Powder, Baking Soda and Salt).
In a separate bowl, Mix Oil and Yogurt well. Stir in the Milk and Vanilla Essence.
Make a well in the dry ingredients and add the wet mixture slowly in parts while mixing. Do not overmix. Remember that a lumpy batter makes the best muffins.
Add in the 3/4 cup of Blueberry Pie filling and mix lightly. Line the muffin tray with the paper cups and fill the cups half full with the batter.
Bake in pre-heated oven for about 25-28 minutes or until a toothpick inserted in the center comes out clean.
Let the muffins cool down for 5 minutes before removing from the tray and then cool off on wire rack.
