Here it is, the rule that will change your life: When in doubt, use a little less. You can always add more butter, but you can’t un-butter a dish (unless you’re a wizard). So start with 3 tablespoons if you’re unsure, then taste, then add the final tbsp if needed.
But honestly, most recipes are forgiving. A half-stick is not an exact science—it’s a delicious guideline. And if your cake comes out a bit greasy? Call it “extra moist.” Own it.
Let’s Test Your Butter Knowledge (Pop Quiz!)
Question: You need half a stick of butter for a recipe, but your roommate used the last stick to butter a squirrel. (Don’t ask.) Do you: a) cry, b) use margarine and lie, or c) remember that half a stick is also ¼ cup, and just grab that from the fridge? Answer: c, obviously, because now you’re a butter genius.
Also, never trust a roommate who butters squirrels. Just saying.
