These St. Patrick’s Day Green Matcha Cupcakes are soft, fluffy cupcakes made with butter, vanilla, and a touch of matcha powder for a festive green color. Topped with creamy vanilla buttercream frosting and fun sprinkles, these cupcakes are easy to make and are a sweet treat for St. Patrick’s Day parties, classroom celebrations, or family gatherings.
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners so the cupcakes are easy to remove after baking.In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set the bowl aside while you prepare the wet ingredients.
In a large mixing bowl, beat the softened butter and granulated sugar for about 2 minutes, until the mixture looks light and fluffy. Add the eggs one at a time, mixing after each addition. Stir in the vanilla extract.
Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk and milk. Mix gently until the batter is smooth, but avoid overmixing.
Add a few drops of green food coloring until you reach your preferred shade. If you're using matcha powder, mix it into the batter as well.
Divide the batter evenly among the cupcake liners, filling each about three-quarters full. Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
Let the cupcakes cool in the pan for a few minutes before transferring them to a wire rack. Make sure they are completely cool before adding the frosting.
Beat the softened butter until creamy. Gradually add the powdered sugar, mixing on low speed at first to keep it from spreading everywhere.Add the vanilla extract, salt, and 2 tablespoons of cream or milk. Beat until the frosting is light and fluffy. Add a little more cream or milk if needed to reach a smooth, pipeable consistency.
Pipe or spread the vanilla frosting over the cooled cupcakes. Finish with chocolate shavings, colorful sprinkles, or other St. Patrick’s Day decorations.Serve them right away or store them in an airtight container until you're ready to share.
