Deciding between oil and butter for your cupcakes is like choosing the perfect playlist for your baking session—it all comes down to personal vibes! Opting for oil brings that extra moisture and fluffiness without a strong flavor allowing the vanilla or lemon or whichever flavor you choose to shine through, and it also stays well in the fridge without hardening up. Being cost effective it's your go-to for whipping up a cupcake batch in advance or for a fuss-free baking day. On the flip side, butter brings a rich taste, adding a cozy feel to your cupcakes, though they might be a bit denser. So, if you're planning a cupcake fiesta ahead of time, oil is your easy-breezy choice, but if it's a spontaneous gathering, butter cupcakes might just steal the show.
