01 - Preheat oven to 350°F. Grease a standard 10-inch Bundt pan with butter or nonstick spray, ensuring all grooves are thoroughly coated.
02 - In a large bowl, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, cloves, and salt until evenly combined.
03 - In a separate bowl, beat softened butter, granulated sugar, and light brown sugar with an electric mixer on medium speed until light and fluffy.
04 - Add eggs one at a time to the creamed mixture, mixing thoroughly after each addition. Blend in pumpkin puree, sour cream, and vanilla extract until the mixture is smooth.
05 - Gradually add the dry ingredient mixture to the wet mixture, stirring just until incorporated. Do not overmix.
06 - Pour the batter evenly into the prepared Bundt pan, smoothing the surface with a spatula.
07 - Bake for 50 to 60 minutes, or until a toothpick inserted into the center emerges clean.
08 - Allow the cake to cool in the pan for 15 minutes. Invert onto a wire rack to cool completely.
09 - In a small bowl, whisk together powdered sugar, maple syrup, milk, and vanilla until smooth and thick.
10 - Once the cake is fully cooled, drizzle with the maple glaze. Let glaze set before slicing.
