Method
- Heat oven to 350°F and line 9x13 pan with parchment paper. Mix cake mix, melted butter, egg, and vanilla until just combined. Don't overmix or you'll make the base tough. Press into pan evenly with clean hands. Bake 15 minutes until set but not brown.
- Beat room temperature cream cheese until completely smooth with zero lumps. Add eggs one at a time, beating well after each. Pour in melted butter slowly while mixing. Add powdered sugar gradually until silky. Add vanilla and beat until combined.
- Pour gooey mixture over hot base layer immediately. Spread evenly with spatula but don't overthink it. Bake 25-30 minutes until center jiggles slightly but edges are set. Top should be light golden, not brown. Internal temp should hit 160°F.
- Let cool completely at room temperature for at least 3 hours. Dust with powdered sugar before serving. Cut with sharp knife, cleaning between cuts. Should have distinct layers when done right.

Notes
The secret to perfect gooey butter cake lies in room temperature cream cheese and patience during cooling - rush either step and you'll get lumpy texture or messy squares that fall apart. This tastes even better the next day as flavors meld into pure buttery perfection.
