I wanted to recreate a childhood classic that my mom would make but make it my usual healthier version and dare I say I think these are even better than the original! These lemon bars are a serious crowd pleaser and are just perfect for this warm weather that we are having! Something about sunny warm weather makes me crave sweet and tart lemony desserts! Bring this recipe to a brunch, a BBQ, in to work, or just keep them on hand for yourself when you need something sweet and lemony!
