Method
- Preheat your oven to 350°F (175°C). Line a 9x13-inch baking dish with parchment paper, leaving overhang for easy removal.
- In a large bowl, mix cake mix, melted butter, and egg until crumbly but cohesive. Press firmly into the prepared pan to form an even base.
- In another bowl, beat softened cream cheese, egg, vanilla, and melted butter until smooth. Gradually add powdered sugar until glossy and creamy.
- Spread cream mixture evenly over the base. Drop spoonfuls of pistachio butter across the surface and swirl gently with a knife to create marbled patterns.
- Bake for 30–35 minutes until edges are set and center still jiggles slightly. Cool completely before slicing. Sprinkle with flaky sea salt before serving.
Notes
Try variations like adding citrus zest, spices, or swirling in Nutella. For gluten-free, use a certified GF cake mix. Cake improves overnight in flavor and texture—store chilled for best results. Serve with whipped cream or berries for a balanced finish.
