Start by cutting all of the croissants into four pieces then place half of them to the bottom of a tall baking pan. on top of the croissants evenly distribute half of all the berries.
In a large bowl add 8 oz room temperature cream cheese and 1/3 cup white granulated sugar with either a hand mixer or a stand mixer, whip the cream cheese and sugar until it becomes smooth and creamy. (about 5 minutes)
Next, beat in 2 eggs into the cream cheese mixture, just enough to incorporate them into the cream cheese. About one minute.
Then add in 1 tea spoon of vanilla extract, lemons zest, and 3/4 cup milk. Mix to incorporate.
Pour half of the cream cheese mixture over the first layer of the croissants and berries. Using a spoon, press down on the croissants so the cream cheese mixture soaks into them.
Repeat this process with the rest of the ingredients. Cover with plastic wrap and let it soak over night or at least 1 hour.
Bake uncovered at 375 for 30 minutes or until the top is slight golden. Dust with a little powdered sugar.
