Preheat oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with cooking spray.

Unroll one package of crescent roll dough and press into the bottom of the prepared baking dish, sealing seams.

In a bowl, beat softened cream cheese and 1/2 cup sugar until smooth. Add juice and zest from one lemon and mix until combined.

Spread cream cheese mixture evenly over the crescent dough in the dish.

Unroll the second crescent roll package and place over the cream cheese layer, gently pressing seams together.

Drizzle melted butter over the top layer of dough.

Mix remaining lemon zest and juice with 3 tablespoons of sugar and sprinkle over the buttered dough.

Bake for 25–30 minutes or until top is golden brown.

Let cool completely at room temperature, then chill for at least 2 hours.

Slice into bars and serve chilled.
