In a separate bowl, whisk the flour, baking powder, salt, cinnamon, nutmeg, and cloves together.

Add the wet ingredients to the dry ingredients as you beat the mixture on low.

Divide the dough into 2 sections (about 494 grams each), and form each section into a log about 12 inches long.
Place the logs lengthwise on a large baking sheet. Then, flatten the logs to about ¾-inch thickness.
Bake for 18-20 minutes, or until the logs are puffed up and have slight cracks in the middle.
Let cool before slicing into rectangles on the diagonal.
