Of course! We recommend preparing the recipe according our instructions and tasting the finished frosting before adding more cinnamon. Depending on your preference you can add 2 teaspoons or up to a tablespoon of cinnamon. For best results, only add little amounts of cinnamon at a time until reaching the desired flavor. Be aware that fresh cinnamon is usually more potent in flavor than spices that have been sitting on the spice rack for a while.
