I use kefir in the batter and it makes the bread super moist. I love this super healthy food so much that I try to include it in our daily diet in several ways. Whenever a recipe calls for milk or buttermilk, I replace them with kefir. It is healthier and makes the baked goody moister. On the other hand, if you can’t find kefir, you can still use buttermilk or yogurt to have a similar result.
