Method
- Preheat oven to 350°F (175°C) and line baking sheets with parchment. Beat butter and sugar together for 3–4 minutes until pale and fluffy.
- Beat in the egg and vanilla extract until fully combined. Scrape down the bowl as needed.
- Sift flour, cocoa powder, baking soda, and salt into the bowl. Mix on low speed just until combined.
- Roll dough into 1.5-inch balls and place 2 inches apart. Bake for 8–10 minutes until edges are set and centers remain soft. Cool completely.
- Beat butter, powdered sugar, milk, peppermint extract, and green gel coloring until smooth and fluffy. Spread frosting evenly over cooled cookies.
- Place frosted cookies in the freezer for 15–20 minutes until frosting is firm.
- Melt chocolate chips with oil in 30-second intervals until smooth. Spoon ganache over frozen frosting and allow to set.
Notes
Freezing the frosted cookies before adding ganache is essential for clean, professional layers.
