Pumpkin Spice Coffee Cake

Preheat the oven to 400 degrees F (200 degrees C). Spray a 10-inch fluted tube pan (such as Bundt®) with cooking spray. Coat with cinnamon sugar.

Beat sugar and butter together in a large bowl using an electric mixer until fluffy. Add eggs, blending 1 at a time. Add pumpkin pie spice and vanilla extract and combine.

Mix flour, baking powder, and baking soda together in a separate bowl. Alternate adding flour mixture and sour cream to egg mixture a little at a time, starting and ending with flour mixture.

Mix brown sugar and cinnamon together for topping in a small bowl. Pour 1/3 of the cake mixture into the prepared pan. Top with 1/2 of the brown sugar mixture. Repeat once more.

Bake in the preheated oven for 8 minutes. Reduce oven temperature to 350 degrees F (175 degrees C). Continue baking until a toothpick inserted into the center of the cake comes out clean, about 40 minutes.

Remove from the oven and let cool for 10 minutes before transferring to a plate.
