Measure your flour properly. This is always my #1 baking tip. Do not ever scoop a measuring cup into your flour. This will always lead to using too much flour. (Trust me, I've learned the hard way that I need to measure properly!) Instead, sprinkle spoonfuls of flour into your measuring cup and swipe excess flour off with the back of a knife. Or better yet, weigh your flour. 1 cup of flour equals 125 grams.
