Creating these Fresh Orange Vanilla Muffins is simple if you follow these clear steps:

1. Preheat your oven to 350°F (175°C) and line a muffin pan with paper liners.
2. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
3. In another bowl, whisk together the melted butter, fresh orange juice, buttermilk, eggs, orange zest, and vanilla extract until smooth.
4. Gradually pour the wet ingredients into the dry ingredients. Mix until just combined; do not over-mix.
5. Spoon the batter evenly into the prepared muffin pan, filling each liner about 2/3 full.
6. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
7. Remove from the oven and allow the muffins to cool in the pan for about 5 minutes.
8. Transfer the muffins to a wire rack to cool completely.

These straightforward steps will guarantee your Fresh Orange Vanilla Muffins turn out incredibly delicious every time!
