To prepare a sour cream pumpkin bundt cake with pumpkin glaze recipe, first you need to prepare the cake batter. First, you will need the following ingredients: Preheat the oven to 350?F (180?C) and grease and flour two 8-inch round cake pans. Sift the flour, baking powder, sugar, and salt into the bowl of an electric mixer. Add the butter and mix until the mixture is light and fluffy, about 5 minutes. In another bowl, mix the pumpkin puree with the sugar and vanilla until it is smooth and creamy. Pour the wet mixture over the dry mixture and stir to combine. If the batter is too dry, add more flour until you reach your desired consistency. Bake the cakes for 35 to 40 minutes, or until they are golden brown. Remove from oven and let cool before serving.
