To prepare a pumpkin snickerdoodle bundt cake recipe, you'll first need to prepare the cake batter. Preheat the oven to 350?F (176?C) and grease and flour two 8-inch round cake pans. Mix the flour, baking powder, sugar, cinnamon, and salt together. Pour the dry ingredients into the wet ingredients and mix until just combined. Add the pumpkin puree and stir to combine. Bake the prepared cake for 35 to 40 minutes, or until the toothpick inserted in the center comes out clean. Let cool for 10 minutes before removing from the pan.
