Ingredients:

  • 1 box (15.25 oz) yellow cake mix
  • 1 large egg, room temperature (for crust)
  • 0.5 cup unsalted butter, melted and slightly cooled
  • 8 oz full-fat cream cheese, softened
  • 2 large eggs, room temperature (for topping)
  • 1 tsp pure vanilla extract
  • 3.75 cups powdered sugar

Instructions:

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9x13 pan and line with parchment paper.
  2. In a large bowl, combine the yellow cake mix, one egg, and the melted butter. Mix until a soft dough forms.
  3. Press the mixture firmly and evenly into the bottom of the prepared 9x13 pan to form the crust.
  4. In a separate bowl, beat the softened cream cheese until smooth and aerated, about 2 minutes.
  5. Add the two remaining eggs and vanilla extract to the cream cheese. Beat on medium speed until fully incorporated.
  6. Reduce mixer speed to low and gradually add the powdered sugar. Increase speed to medium-high and beat for 2–3 minutes until glossy.
  7. Pour the cream cheese mixture over the cake base and spread to the edges with an offset spatula.
  8. Bake for 40–45 minutes at 350°F (175°C). The edges should be golden brown and puffed, while the center should still jiggle slightly when shaken.
  9. Remove from the oven and let cool completely in the pan on a wire rack to allow the gooey center to set.
