1.Always use butter.
2. Make sure you’re using the right size eggs for your recipe, and bring those to room temperature.
3. If your cookies are spreading too much as they bake, try popping them in the freezer or fridge for 10 minutes.
4.Cream the butter and sugar.
5.Handle the dough gently.
6.If you run out of sheets to put them on then just turn a baking tray upside down and drop the cookies on that.
7.Use a cooling rack after baking.
8.Store cookies in an air tight tin with a slice of bread as the moisture from the bread will keep your cookies soft and fresh.
