Key lime desserts hit that magical sweet-tart balance that makes your taste buds wake up and do a little dance. I fell hard for key lime flavors years ago after one bite of a pie that tasted like sunshine with attitude. Ever since, I keep finding excuses to squeeze limes into desserts that probably didn’t ask for it—but wow, they thank me later. Ready to talk creamy, zesty, and borderline addictive treats? Let’s get into it.

1. Classic Key Lime Pie

Instructions

  1. Mix crumbs, butter, and sugar, then press into a pie pan.
