Preheat your oven to 350°F (175°C) and grease a loaf pan.
In a large bowl, whisk together the flour, sugar, baking powder, cinnamon, and salt.
In another bowl, mix the melted butter, eggs, milk, and vanilla extract until well combined.
Gradually add the wet ingredients to the dry ingredients, stirring until just combined.
Pour the batter into the prepared loaf pan and bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean.
Let the bread cool before slicing and serving. Enjoy!
