Instructions

    Cup of Yum
  1. Preheat oven to 350 degrees. Line a 9×13 baking pan w/ foil and coat well with cooking spray. Set aside.
  2. FOR 1ST LAYER: In a large bowl add cake mix, softened butter, egg and vanilla. Mix well with hands or spoon until well combined. (you may need to use a tablespoon of water to help combine)
  3. Press dough into prepared pan.
  4. FOR 2ND LAYER: Mix all 2nd layer ingredients together in a medium bowl. Mix until combined, then pour over dough.
  5. FOR 3RD LAYER: Sprinkle the white chocolate chips evenly over 2nd layer.
  6. Bake for 20-23 minutes. Center may seem jiggly but will set while it cools. DONT OVERBAKE!
  7. While bars are baking, make frosting. Add butter and white chocolate to a microwave-safe bowl. Heat in 30 second increments until slightly melted. Stir together until melted. Add powdered sugar, cream and vanilla. Stir until smooth.
  8. Remove bars from oven and let cool 5-10 minutes and then drizzle with frosting. Let bars cool completely before serving. (I refrigerated mine to have them cool faster) Cut into squares and serve!
