If you love bright citrus desserts and nutty, buttery cakes, this recipe is going to steal your heart. This lemon pistachio loaf cake is soft, plush, and bursting with fresh lemon flavor. Ground pistachios replace some of the flour, adding subtle richness and delicate nuttiness to the crumb. It’s the kind of simple-yet-special cake that works just as well on a brunch table, tucked into a spring dessert spread, or with afternoon tea.
