Preheat your oven to 350 degrees F. In a medium bowl, sift together the cake flour, baking soda, baking powder, spices and kosher salt three times.
3 (375 g) cups Cake flour , 1 teaspoon Baking soda, 1 teaspoon Baking powder , 1 ½ teaspoons Kosher salt, 1 tablespoon Pumpkin pie spice , ½ teaspoon Ground all spice
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugar at medium low speed until combined. Increase speed to medium and continue to beat until pale and fluffy, about 3 minutes, stopping halfway to scrape the sides of the bowl.
1 (227 g) cup Unsalted butter, 2 (400 g) cups Granulated sugar, ¾ (165 g) cup Light brown sugar
Add in the eggs, one at a time on the stir setting first. Then, when they are almost combined, increase the speed to medium and mix the batter together for an additional 10 seconds. Scrape the sides and bottom of the bowl before and after adding each egg.
3 large eggs
Stir in the pumpkin puree and vanilla extract, stopping to scrape the bottom and sides of the bowl. (The batter may look broken, but it will come back together).
1 (425 g) 15 oz Canned pumpkin puree , 1 tablespoon Rodelle Pure Vanilla Extract
With the mixer on low, add the flour mixture to butter mixture in three additions and mix until just combined. When adding the last addition of flour, mix until almost combined, then remove the bowl from the stand mixer and mix by hand using a rubber spatula. Scrape the bottom and sides of the bowl to ensure everything is incorporated.
Spray a 12 cup bundt pan with nonstick baking spray. Using a fine pastry brush, spread the baking spray to coat the pan making sure to get into all the nooks and crannies. Transfer the cake batter to the prepared pan and smooth the top with an offset spatula. Firmly tap the pan on the counter to release any air bubbles then bake for 65 to 70 minutes or until a toothpick or cake tester comes out clean with a few moist crumbs.
Allow cake to cool in pan for 15 minutes on a wire rack. Invert the cake onto the wire rack to cool completely, about 2 hours.
