"adapted from Taste of Home. We've been making these recipes about once a week and experimenting with mix-ins! Instead of the chopped apple, we've really liked these with 1 - 1 1/2 cups of blueberries, 1 1/2 cups frozen cherries (not thawed), or 1 cup sliced strawberries. Darrol, my son, loves that he gets to choose each week's muffin addition!..."
