Most cheesecake muffin recipes, like these raspberry cheesecake muffins, combine cheesecake with a second flavor, from fruit to chocolate to pumpkin spice. But these muffins were just plain, non-descript cheesecake in a vanilla batter. They also required quite a bit of effort in terms of preparation. These muffins come with a batter that you mix as well as a cheesecake filling, which you're instructed to layer between portions of the wet muffin batter for a cheesecake center.
