Preheat your oven to 350°F (175°C) and grease and flour a loaf pan to prevent sticking.

In a medium bowl, whisk together the dry ingredients: flour, baking powder, baking soda, salt, cinnamon, nutmeg, and allspice.

In a large bowl, whisk together the wet ingredients: melted butter, granulated sugar, brown sugar, and eggs. Add apple cider and vanilla extract, mixing until smooth.

Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined.

Pour the batter into the prepared loaf pan and smooth the top.

Bake in the preheated oven for 45-50 minutes or until a toothpick inserted in the center comes out clean.

While the loaf is baking, mix the cinnamon sugar crust ingredients in a small bowl.

Once baked, remove the loaf from the oven, brush it with melted butter, and sprinkle the cinnamon sugar mixture over the top.

Allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
