I have had people tell me this looks hard to make, but trust me, it is not. There is just one little trick: roll the dough out into a rectangle and then move it to your baking sheet BEFORE you try to make the ladder. You can't move the ladder (and keep it's shape) after it is filled. This dough is the real secret to this recipe.
Preheat oven to 350°
1 cup butter softened
1 cup sour cream
2 cups flour
Mix ingredients with an electric mixer (the dough will be a little sticky before it is chilled). Divide dough in half (this recipe makes TWO ladders). Put each ball of dough in some plastic wrap and rough it into a large disk shape…cover well and refrigerate 1 hour (extremely important).
After an hour, remove from fridge and flour your counter top and rolling pin. Roll one of the disks into a rectangle about 15” x 10”. Pick up the crust rectangle (it will not break) and lay it on a lightly greased baking sheet.
Now I could describe, at length how to do this next step, but a picture will describe it much quicker:
