Preheat oven to 350°F. Generously grease a 10 to 12 cup Bundt pan with baking spray containing flour (or butter and flour).
In a large mixing bowl, whisk together the flour, granulated sugar, baking powder, apple pie spice, and salt.
In a separate bowl, whisk together the apple cider, egg, melted butter, and vanilla until well combined.
Pour the wet ingredients into the dry ingredients and stir gently until just combined. The batter will be slightly thin; do not overmix.
Pour the batter evenly into the prepared Bundt pan.
Bake for 50 to 65 minutes, or until a toothpick or long skewer inserted into the thickest part comes out with a few moist crumbs, but no wet batter. Begin checking at 50 minutes.
Let the cake cool in the pan for 10 to 15 minutes, then carefully invert onto a wire rack.
While still warm, brush or drizzle the ¼ cup apple cider evenly over the cake.
In a small bowl, mix the sugar and apple pie spice. While the cake is still warm, sprinkle and gently press the mixture over the entire surface until well coated. Rotate as needed for even coverage.
Allow the cake to cool completely before slicing.
