Pumpkin Spice Bundt Cake with Salted Caramel Sauce

1. 1Heat the oven to 350°F and arrange a rack in the middle. Coat a 12-cup Bundt pan with vegetable oil and flour and tap out any excess flour.
2. 2Place the measured flour, baking powder, cinnamon, cloves, allspice, nutmeg, baking soda, and salt in a large bowl and whisk to aerate and break up any lumps; set aside.
3. 3Place the sugar and measured oil in the bowl of a stand mixer fitted with a paddle attachment. Beat on medium speed until the sugar is incorporated, about 1 minute. Stop the mixer and scrape down the sides of the bowl and the paddle with a rubber spatula.
4. 4Return the mixer to medium speed and add the eggs 1 at a time, beating well after each addition, about 1 1/2 minutes total mixing time. Reduce the speed to medium low, add the pumpkin, and beat until just combined, about 30 seconds. Stop the mixer and scrape down the sides of the bowl and the paddle with the rubber spatula.
5. 5Turn the mixer to low speed, slowly add the reserved flour mixture, and beat until almost completely incorporated, about 1 minute. Remove the bowl from the mixer and fold in any unincorporated flour at the edges with the rubber spatula, making sure to scrape to the bottom of the bowl.
6. 6Pour the batter into the prepared pan and bake until a cake tester or toothpick inserted into the center of the cake comes out clean, about 1 hour to 70 minutes.
7. 7Remove the pan to a wire rack and let cool for 15 minutes. Turn the cake out onto the wire rack and cool completely.

For the salted caramel sauce:

1. 1Melt the butter in a medium heavy-bottomed saucepan over medium-high heat. Add the sugar, cream, and corn syrup; stir until the mixture is smooth; and bring to a boil. Continue to boil, stirring occasionally, until slightly thickened, about 3 minutes more. Remove from the heat, stir in the salt, and set aside to cool slightly.

To serve:

1. 1Dust the cake with powdered sugar (if using), slice, and serve with the salted caramel sauce.
