I prefer using all-purpose flour with a protein amount that is between 10-11%, Cornstarch Helps give a light and soft cake, Sugars The granulated sugar helps sweeten, as well as give moister to the cake, Baking powder and baking soda: Help leaven and rise the cake, so it has light and fluffy texture, Salt Helps enhance the flavor of the chocolate cake, Oil Use a flavor neutral oil, such as canola oil, Sour cream gives lots of moister to the cake, as well a helps give the cake a great structure, Butter The butter is used in the buttercream and in the cake. Bring it out and let it come to room temperature, Chai spices: This homemade chai spice mix is a blend of 6 spices, ground cardamom, cinnamon, ginger, all spice, nutmeg and black pepper.
