Measuring ingredients by weight
Baking and cooking are very different.  Cooking involves a little of this and a little of that, but baking is very precise.  The problem with using measuring cups for measuring dry goods like flour and sugar is that they can settle and get compacted, or be fluffed up with air so you don't get an accurate measure.  The result is that your get too much or not enough of that ingredient which can substantially alter the result of your finished recipe.  To fix this, get an inexpensive kitchen scale (we use this one) and weigh them.  You can even use it for weighing liquids.  In addition to being more accurate, it's faster, easier and leaves fewer dishes to clean up.

Greek yogurt
What is the deal with Greek yogurt popping up everywhere?  Greek yogurt has been around for a long time, but is gaining popularity in the US because of it's many health benefits including: high protein content, low sodium and carbohydrates, and probiotics.  There are many flavored versions available as a substitute for eating like regular yogurt, but what I am excited about is using plain Greek yogurt in place of sour cream.  It is indistinguishable from sour cream in most applications including baking.  Making this simple swap will save over 300 calories and 45 grams of fat per cup all while adding healthy benefits.  Why are you still reading this?  Get to the store and buy you some Greek yogurt!
