For the Pumpkin Cake: Preheat oven to 350°F (170°C). Grease and flour bundt cake pan well.
In a medium sized bowl, whisk together flour, baking powder, baking soda, spices and salt. Set aside. In a large mixing bowl, whisk together sugar, oil, eggs, vanilla, pumpkin and sour cream until well combined. Add flour mixture and stir to combine. Pour into prepared pan.
Bake for 45-50 minutes, until a toothpick inserted in the center comes out clean. Cool in pan on a wire rack for 10 minutes. Loosen cake from sides of pan, invert onto a wire rack, remove pan and cool completely.
For the Caramel Glaze, combine butter, cream, brown sugar and salt in a medium saucepan. Stir over medium-high heat until mixture begins to boil. Boil and stir for 2-3 minutes. Remove from heat and allow to cool for 5 minutes.
Add sifted powdered sugar and vanilla and whisk to combine. Immediately pour over cooled cake. If the glaze gets too thick to pour, you can stir in 1-2 teaspoons of warm water. Sprinkle with toasted chopped pecans if desired.
Notes
*To toast the pecans: Preheat oven to 350° (170°C) and chop pecans. You will need about ¼ cup (30g) of chopped pecans. Spread the chopped pecans on a baking sheet and bake for about 8 minutes, until fragrant and darker in color.Cake recipe adapted from:Chef in Training.
