Ingredients

Cake

  • 15.25 ounces boxed yellow cake mix
  • 3 eggs
  • 1/2 cup vegetable oil
  • 1 cup water

Cream Cheese Filling

  • 1/2 cup sugar
  • 4 Tablespoons butter, softened
  • 4 Tablespoons milk
  • 4 Tablespoons flour
  • 16 ounces cream cheese, room temperature
  • 1 teaspoon vanilla extract
  • 4 eggs

Icing

  • 16 ounces chocolate fudge frosting

Instructions

  • Preheat oven to 350 degrees F. Spray a 13 x 9 inch baking dish with nonstick cooking spray.
  • In a large bowl, beat cake mix, eggs (3), oil and water for 2 minutes or until smooth. Set aside.
  • In a separate bowl, beat sugar, butter, milk, flour, cream cheese, vanilla and eggs (4) until smooth and lump free.
  • In the prepared dish, add half the cake batter; pour cream cheese mixture slowly over top. Top with remaining cake batter.
  • Bake for 35 to 40 minutes or until a toothpick comes out clean.
  • Let cool completely before icing with chocolate fudge icing.
  • Store in the refrigerator.

Notes

  • Substitute margarine for butter, if desired. Be sure each is at room temperature.
  • Use a yellow box cake mix for this shortcut Boston Cream Pie.  A white cake mix would work but yellow is the classic flavor. 
  • Traditional Boston Cream Pie has a chocolate fudge icing. Feel free to make homemade, but we usually buy the pre-made tubs.  You can use chocolate but chocolate fudge is the classic flavor. 
  • Let the Boston Cream Cake cool completely before icing. 
  • Be sure to refrigerate Boston Cream Pie.  
  • Try our Granny's Double Chocolate version!
