Preheat your oven to 325˚F. Place a piece of parchment paper or foil on a work surface and set a cooling rack on top of it (for easy cleanup).
Add the baking powder, all of the spices and the salt. Whisk again until everything is well incorporated.
Add the flour and whisk just until incorporated and the batter is fairly smooth.
Spray a 12-cup Bundt pan (or 2 9x4 or 9x5-inch loaf pans) generously with baking spray. With a small piece of paper toweling, rub the baking spray to make sure all the grooves and crevices are coated. Spray the pan again lightly.
