Use Coffee Instead of Water in the Batter for a Rich, Flavorful Cake
The boxed cake mix isn’t as good as the scratch-off recipe, but it’s quick and convenient. If you rely on the box, give it a helping hand by replacing the water in the batter with coffee. This will give the final cake a deeper and richer flavor.
You can use leftover coffee to do this, or brew a fresh pot (but if you do, let it cool). You will get a rich, nutty flavor from coffee, which you might think would make your cake taste like coffee, but it works even if you don’t make a chocolate cake. Just swap out the water in the recipe for the same amount of coffee, or you can do half if you’re worried about the aroma being overwhelming. You can also use other kitchen products to add flavor to the packaged mix, such as milk, flavored liqueurs, or even mayonnaise . Follow the link below to get some suggestions.
