Ingredients:

  • 1 box (15.25 oz) Yellow Cake Mix
  • 1/2 cup (115g) Unsalted Butter, melted and slightly cooled
  • 3 Large Eggs, room temperature (divided)
  • 2 tsp Vanilla Extract (divided)
  • 8 oz (225g) Full-Fat Cream Cheese, softened to room temperature
  • 3 ¾ cups (450g) Powdered Sugar (plus extra for dusting)

Instructions:

  1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch pan with butter or non stick spray. Note: Proper greasing is vital since the sugar in the topping becomes very sticky.
  2. In a large mixing bowl, combine the yellow cake mix, 1/2 cup melted butter, one egg, and 1 tsp vanilla extract. Mix until a stiff, dough-like consistency forms.
  3. Press the base mixture firmly and evenly into the bottom of the prepared baking pan using your fingers or the back of a spoon.
  4. In a separate bowl, beat the 8 oz cream cheese until smooth. Add the remaining two eggs and 1 tsp vanilla extract, beating until fully incorporated.
  5. Gradually add 3 ¾ cups powdered sugar on low speed, then increase to medium until the topping is glossy and pale.
  6. Pour the cream cheese mixture over the cake base, spreading it to the edges. Bake for 40 minutes until the edges are golden brown and the center still has a slight jiggle.
  7. Allow the cake to cool completely in the pan to set before slicing into bars and dusting with extra powdered sugar.
