Ingredients:
- 1 box (15.25 oz) Yellow Cake Mix
- 1/2 cup (113g) Unsalted Butter, melted and slightly cooled
- 1 Large Egg, room temperature (for base)
- 8 oz (226g) Full-fat Cream Cheese, softened to room temperature
- 2 Large Eggs, room temperature (for filling)
- 1 tsp Pure Vanilla Extract
- 450g Powdered Sugar (Confectioners' sugar), plus extra for dusting
Instructions:
- Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an inch of overhang on the sides for easy removal.
- In a large mixing bowl, combine the dry yellow cake mix, melted butter, and one egg. Stir until a thick, soft dough forms. Note: It will feel more like cookie dough than cake batter.
- Press this mixture evenly into the bottom of the prepared pan. Use the back of a spoon or your clean hands to get it into the corners.
- In a separate bowl, beat the 8 oz of softened cream cheese using an electric mixer until smooth. Beat until no lumps remain before adding other ingredients.
- Add the two remaining eggs and vanilla extract to the cream cheese. Mix on medium speed until fully incorporated and the color is uniform.
- Gradually add the powdered sugar (450g) to the cream cheese mixture one cup at a time. Beat on low speed until the batter is silky and thick.
- Pour the cream cheese batter over the cake base in the pan and spread it to the edges with a rubber spatula.
- Bake in the center rack for 35 to 45 minutes. Watch for the edges to turn a deep golden mahogany.
- Check the center. It should still have a slight jiggle when the pan is gently shaken. It should not look like liquid, but it shouldn't be firm either.
- Allow the cake to cool completely in the pan for at least 2 hours before slicing into 24 bars. Dust with extra powdered sugar if desired. > Chef's Tip: If you want an even cleaner slice, put the cooled cake in the fridge for an hour. Use a hot, wet knife to cut through the layers, wiping the blade between every single cut. It sounds tedious, but it’s how you get those perfect, bakery style squares.
