It sounds like there might be an issue with the butter-to-flour ratio in your recipe. When measuring flour and white sugar, it’s important to overflow the cup and then level it off with the back of a knife. For brown sugar, make sure to pack it well into the cup. Many people may not be aware of how to properly use measuring cups, so it’s essential to double-check. Also, be careful not to mix up tablespoons and teaspoons and to use the correct measuring cups.
Chilling the dough before baking can also make a big difference, even if the recipe doesn’t mention it. It’s a helpful tip that can improve the texture and consistency of your cookies.
@jude Or use actual measurements by weight instead of cups.
I experienced the same thing, however I used powdered sugar for flour.
