This Pistachio Gooey Butter Cake is rich, creamy, and loaded with nutty pistachio cream that melts right into a buttery vanilla base. It’s chewy on the edges, jiggly in the center, and so dang addictive.
In a large bowl, use a hand mixer to beat together the cake mix, melted butter, and egg until combined—about 2 minutes. Press into the bottom of the parchment paper-lined baking dish.
Wipe out that same bowl (doesn’t have to be all the way clean!). Add the cream cheese, egg, vanilla, and melted butter and use a hand mixer to beat it until smooth. Mix in the powdered sugar, cup by cup, until it’s smooth and creamy.
Add to the baking dish then add spoonfuls of the pistachio butter all over the top of the filling and swirl gently with a knife to create a cute organic pattern - making sure to stay on the surface layer.
Place it in the oven and bake for 30–35 minutes, or until the edges are set and starting to turn golden brown but the center is still jiggly.
Let cool and stiffen slightly before cutting into squares.
Sprinkle with flaky salt before serving.
