How to Make St. Patrick’s Day Green Matcha Cupcakes

Step 1: 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.

Step 2: 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.

Step 3: 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.

Step 4: 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.

Step 5: 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.

Step 6: 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.

Step 7: Pipe or spread the vanilla frosting over the cooled cupcakes. Finish with chocolate shavings, colorful sprinkles, or other St. Patrick’s Day decorations.

Step 8: Serve them right away or store them in an airtight container until you’re ready to share.
Important Recipe Notes

- Use room-temperature ingredients: Let the butter, eggs, buttermilk, and milk come to room temperature before mixing. This helps the batter combine smoothly and makes soft cupcakes.
- Do not overmix the batter: Mix just until the ingredients are combined to keep the cupcakes light and fluffy.
- Add green gel food coloring a little at a time until you get your desired shade. The color may look slightly different after baking.
- Matcha powder adds a mild earthy flavor and a natural green tint. For a brighter green color, you can use green food coloring along with the matcha.
- Cool completely before frosting: Make sure the cupcakes are fully cooled before adding the buttercream, or the frosting may melt.
- Adjust the frosting consistency: Add the cream or milk gradually. Use less for thicker frosting or a little more if you need a softer consistency for piping.
- Start checking the cupcakes at 18 minutes. Insert a toothpick into the center; it should come out clean or with a few dry crumbs.
- Keep frosted cupcakes in an airtight container in the refrigerator if they contain perishable frosting ingredients. Let them sit at room temperature briefly before serving for a softer texture.
