Ingredients
Method
- Stir lemon cake mix, 1/2 cup melted butter, and 1 large egg until a thick dough forms.
- Press dough into an ungreased 9x13-inch dish in an even layer and set aside.
- Beat cream cheese until smooth, then beat in 2 eggs, vanilla, lemon zest, and lemon juice.
- Gradually mix in 3 1/2 cups powdered sugar and 1/2 cup melted butter, then beat for 2 minutes until glossy.
- Pour topping over crust and spread to edges. Bake at 350°F for 35–40 minutes until edges are golden and center jiggles slightly.
- Cool completely, chill if desired, dust with powdered sugar, and slice.
Notes
The cake needs a full cool-down before you cut it, plan for at least 2 hours on the counter. For the cleanest squares, refrigerate it for an hour before slicing. If you skip the chill, the first piece might be a little messy but will still taste wonderful.
