Heat your oven to 350°F. Spray a 9x13 pan with cooking spray that has flour or put down parchment and hit it with regular spray.

Mix flour, baking powder, and salt in a bowl. In another bowl, beat butter with sugar till it's light and fluffy, about 3-4 minutes. Add the egg, then pour in milk and vanilla. Add your dry mix in three batches, stirring after each one.

Spoon the cake mix into your pan and spread it out flat.

Whip cream cheese until it's creamy. Mix in the melted butter until blended. Toss in eggs, vanilla, and salt, mixing just enough to combine. Slowly add sugar a cup at a time, mixing on low speed until it looks smooth. Don't mix too much.

Drop the cream cheese mix on top of the cake base and smooth it out evenly.

Cook for 35-45 minutes until the edges turn golden and the middle still wobbles a bit. Check it every couple minutes if needed, but watch out - baking too long means the center won't be gooey.

Let the cake sit until it's totally cool, about 3 hours.

Sprinkle some powdered sugar on top. For neat slices, dunk your knife in hot water and wipe it clean between cuts.
