It’s spring! Time for lightness and flavors to match. What’s better than a lemon cupcake? Lemon poppy seed cupcakes! These little cakes are moist and dense and the frosting is amazingly lemony.

For the best taste, always use fresh lemon juice. (To get the most juice, use pressure to roll the lemon on a hard surface before juicing.)  Since this recipe requires lemon zest, there is no way not to have fresh juice!
