Preheat oven to 475 degrees. Line your standard muffin pan with cupcake liners (or grease it down really well)
In a large bowl, mix together 2 eggs, 1 cup granulated sugar, 1/2 teaspoon salt, 1 cup sour cream, 1/2 cup vegetable oil, and 1 tsp vanilla extract.
In a separate bowl, combine 2 cups flour, 1 tsp baking powder, and 1/4 tsp baking soda. Add the flour mixture to the wet ingredients until just combined - careful not to overmix or the muffins will turn out dense.
Using a spatula, gently fold the blueberries into the batter. Again, avoid overmixing.
Spoon the batter into the muffin liners until a little over 3/4 of the way full. Bake at 475 degrees for 5 minutes, then lower the temperature to 350 degreed for 25 minutes until golden brown. Use a toothpick to check if they are done.
Let muffins cool for 5 minutes and then transfer to a cooling rack. Enjoy!
