Turn your oven on to 350°F. Prep a 9x13 pan by lining it with parchment paper if you'd like, then add a layer of cooking spray.

Mix together the dry ingredients—flour, salt, and baking powder—in a medium bowl. In another bowl, cream together the butter and sugar until it’s fluffy, about 3–4 minutes. Beat in the egg, followed by the milk and vanilla. Slowly combine the dry mixture in thirds, mixing a bit each time until fully incorporated.

Spread the batter into the prepared pan, pressing it down into an even layer.

Using a mixer, whip the cream cheese until smooth. Blend in the melted butter until it’s well mixed. Add eggs, vanilla, and salt, beating just briefly to combine. Toss in the powdered sugar one cup at a time—mix on low speed until smooth. Avoid mixing too much!

Pour the cream cheese mixture over the base layer and spread it all evenly.

Pop it into the oven for 35–45 minutes. Look for golden edges and a slightly wobbly middle. Check every couple of minutes if you're not sure, but be careful not to bake too long—the gooey center is the key.

Give it time to fully cool—roughly 3 hours—before cutting it up.

Sprinkle some powdered sugar on top. If you want clean edges, warm your knife in hot water and wipe it dry before each slice.
