Method
- Preheat the Oven:
 - Preheat your oven to 400°F (200°C).
 - Line a muffin tin with paper liners or spray with non-stick spray.
 - Prepare the Batter:
 - In a large mixing bowl, whisk together the Bisquick mix, granulated sugar, and ground cinnamon (if using).
 - In a separate bowl, combine the milk, egg, vegetable oil, and vanilla extract. Whisk until well blended.
 - Pour the wet ingredients into the dry ingredients and gently stir until just combined. Be careful not to overmix; the batter should be slightly lumpy.
 - Fold in Blueberries:
 - Gently fold the blueberries into the batter using a spatula, being careful not to crush them.
 - Fill Muffin Tin:
 - Evenly divide the batter among the prepared muffin cups, filling each about 2/3 full.
 - If desired, sprinkle a little coarse sugar on top of each muffin for a sweet, crunchy topping.
 - Bake:
 - Place the muffin tin in the preheated oven and bake for 13-15 minutes, or until the muffins are golden brown and a toothpick inserted into the center comes out clean.
 - Allow the muffins to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
