Coffee cake is a classic breakfast or brunch pastry that is flavored with coffee or espresso. The cake is typically light and fluffy, with a streusel topping made from cinnamon and chopped nuts. The addition of coffee or espresso to the cake batter gives it a subtle coffee flavor that is both comforting and delicious. Coffee cake is a perfect accompaniment to a hot cup of coffee or tea and is the perfect way to start your day.
