These Matcha Cupcakes with Irish Cream Frosting are the perfect go-to for St. Patricks Day--or for the birthday of someone who loves all things green. To give them their signature look, make sure to measure the flour into your measuring cup by spooning flour from the bag into the cup (and then leveling the flour with the back of a knife or other straight edge). The recipe calls for our Super Fine Cake Flour in the cupcakes and Irish cream liqueur in the frosting as an added bonus.
