Problem: The cookie dough cracks when rolling it.
Solution: Try covering the dough with plastic wrap before rolling. If it still doesn’t come together smoothly, spritz with a little water and knead it together until smooth. Or, if the dough is too cold, allow it to sit at room temperature until softened.
Problem: The cookies spread too much while baking and are too flat.
Solution: Use a higher protein flour and/or less sugar. Flour your hands before shaping to make a more rounded cookie. It also helps to chill the shaped cookie dough before baking. Avoid placing the cookie dough on hot or warm baking sheets.
