Instructions:
Preheat oven and prepare pan: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
Combine ingredients: In a large mixing bowl, combine the pumpkin puree and the spice cake mix. Stir until well blended.
Bake cake: Spread the pumpkin cake batter evenly into the prepared baking dish. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Prepare glaze: While the cake is baking, prepare the apple cider glaze by whisking together the apple cider and powdered sugar in a small bowl until smooth.
Glaze cake: Let the cake cool for 10 minutes in the pan, then drizzle the apple cider glaze over the warm cake.
Serve: Allow the glaze to set for a few minutes before slicing and serving.
