Instructions
 

  • Preheat the oven to 350°F (180°C) and prepare a 9×13 inch pan by greasing and flouring it.

For the Cream Cheese Frosting

  • Beat the softened butter, then add the cream cheese and mix until smooth.
  • Incorporate the lemon juice and gradually add the powdered sugar until the desired sweetness and consistency are achieved.

Decorating

  • Frost the cooled cake or layer cake as desired, optionally garnishing with blueberries and lemon slices.

Notes

Cake flour can be substituted by combining all-purpose flour with cornstarch. Ensure all ingredients are at room temperature for best results. Fresh blueberries are recommended; if using frozen, do not thaw them first.
