For an extra touch of flavor, consider adding a pinch of salt to the cream cheese filling to enhance the sweetness. Ensure the cream cheese is thoroughly softened to prevent lumps in the filling. If you prefer a more pronounced red velvet flavor, add a teaspoon of cocoa powder to the cake batter. These cupcakes are best enjoyed chilled, as the cream cheese filling firms up nicely. To prevent the cupcakes from sticking to the liners, lightly spray the inside of the paper liners with cooking spray before filling.
