  • 15.25 oz. pkg. Duncan Hines Lemon Supreme cake mix
  • 1/2 cup unsalted butter softened, (1 stick)
  • 1/2 cup sugar
  • 1 large egg
  • 1/4 cup milk I used 2%
  • 1 cup white chocolate chips not premiere white baking chips
  • 1/2 of a 14-oz. can sweetened condensed milk (use half can)


  • Mix cake mix, butter, sugar, egg and 2% milk with a whisk until well combined.
  • Mixture will be very thick.
  • Spray a 9x9” glass baking dish with cooking spray.
  • Spread about half of the batter into prepared baking dish.
  • Sprinkle evenly with all of the white chocolate chips.
  • Pour condensed milk over top of the white chocolate chips as evenly as possible.
  • Spoon remaining dough in dabs over top of the condensed milk and spread very gently with a knife to cover as much of the surface area as possible.
  • (You won’t be able to cover all of the top, but most of it will be well covered).
  • Bake at 350° for about 25-30 minutes or until a toothpick inserted in center comes out clean.
  • Cool completely before cutting into bars.


NOTE: You can also use an electric mixer to mix the batter if you use the lowest possible speed. If using a whisk, be sure to get the lumps out of the cake mix.
NOTE: I do not recommend trying to double the recipe and bake in one pan. The white chocolate chips will dissolve into the mixture and you will lose the chunky texture.
