40-Minute Lime Coconut Cake Recipe

This Lime Coconut Cake brings me straight back to a beach vacation we took years ago — flip-flops, salty air, and a slice of coconut cake that changed me. I wanted that flavor, but lighter and less sugary, so I started testing. This version has the perfect balance of zesty lime and creamy coconut, with a moist, tender crumb. It’s the kind of cake you can eat barefoot on the porch with tea… or sneak a slice of straight from the fridge (not that I’ve done that 😄).
