This matcha Funfetti cake recipe is made easy with a food processor. Combine flour, sugar, baking powder, matcha powder, and salt in the food processor, then add in butter, eggs, vanilla extract, and milk. Pulse until the batter is smooth, then fold in rainbow sprinkles. Bake in a preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Let cool before frosting with a matcha buttercream made with matcha powder and powdered sugar.
