What purpose does cinnamon do in cake?

Flavor:

* Warmth and depth: Cinnamon is a warm spice that adds a comforting and complex flavor to cakes, especially those that have a base of brown sugar, apples, or other autumnal ingredients.

* Complementary: It pairs well with many common cake ingredients, like apples, pears, nuts, and spices like nutmeg and cloves.

Texture:

* Moistness: Cinnamon can help to retain moisture in cakes, resulting in a softer and more tender crumb.

Aesthetics:

* Visual appeal: The warm, brown color of cinnamon can enhance the visual appeal of cakes, particularly when combined with other spices like nutmeg or cardamom.

Other benefits:

* Antioxidant properties: Cinnamon has been linked to potential health benefits, including antioxidant properties.

Important Note: The amount of cinnamon you use in your cake will depend on the overall flavor profile you are aiming for. A small amount can provide a subtle warmth, while larger amounts will create a more pronounced cinnamon flavor.
