Cocoa and whole-wheat flour contain bitter compounds that can affect the taste of your baked goods. Baking from scratch allows you to balance the bitterness with other ingredients that can add sweetness, acidity, or saltiness. For example, you can add sugar, honey, or maple syrup to sweeten your baked goods. You can add lemon juice, vinegar, or sour cream to add acidity and brightness to your baked goods. You can add salt or baking soda to neutralize the bitterness and enhance the flavor of your baked goods.
