1 box brownie mix

2 large eggs

1/2 c. vegetable oil

1/4 c. Baileys Original Irish Cream

Preparation

Step 1Make brownies: Preheat oven to 350°. Line a 9"-x-9" pan with parchment paper and grease with cooking spray. In a large bowl, whisk together brownie mix, eggs, oil, and Baileys. Pour into prepared pan and bake until a toothpick inserted in middle of brownies comes out with a few moist crumbs, 30 minutes. Let cool. Step 2Meanwhile, make frosting: In a large bowl using a hand mixer, beat butter until light and fluffy. Add 2 cups powdered sugar and beat until smooth, then add Baileys, mint extract, and a pinch of salt and beat until combined. Add remaining cup of powdered sugar and a few drops of green food coloring and beat until smooth. Step 3Frost cooled brownies, then drizzle with melted chocolate.
