In a mixing bowl, combine warm milk, warm water, and ¼ cup sugar; add yeast and let it sit until foamy.

Add salt, melted butter, egg, and 4 cups flour to the yeast mixture; mix until a dough forms.

Knead the dough on a floured surface until smooth, then place in a greased bowl, cover, and let rise for 1 hour.

Roll out the dough into a rectangle, spread softened butter, and sprinkle with powdered freeze-dried strawberries, 1 cup sugar, lemon zest, and 2 tablespoons flour.

Roll the dough tightly and slice into 12 rolls; place in a greased baking dish.

Let rolls rise for 30 minutes, then bake at 350°F (175°C) for 25 minutes or until golden brown.

For the frosting, beat softened cream cheese, powdered sugar, and 1 teaspoon vanilla extract until smooth.

Spread the frosting on warm rolls and serve.
