Creating these muffins is a breeze with our step-by-step instructions. Follow along to ensure you achieve that perfect melt-in-your-mouth texture.

1. Preheat your oven to 375°F (190°C) and line a muffin tin with liners. This ensures your muffins bake evenly and are easy to remove from the tin.
2. In a large bowl, mix flour, sugar, baking powder, and salt. These dry ingredients provide the base for your muffins.
3. In another bowl, whisk together applesauce, oil, egg, vanilla, and milk. This combination of wet ingredients helps to keep the muffins moist and flavorful.
4. Combine the wet and dry ingredients until just mixed. Avoid overmixing to keep the muffins light and airy. Gently fold in the blueberries to distribute them evenly throughout the batter.
5. Fill muffin cups about 2/3 full. This allows room for the muffins to rise without overflowing.
6. Bake for 18-20 minutes or until the tops are golden and a toothpick inserted into the center comes out clean.
7. Let cool for a few minutes before enjoying. This brief cooling period helps the muffins set and makes them easier to handle.
