Ingredients

Brownies

  • 1 box fudge brownie mix
  • 3 tablespoons Baileys Irish Cream
  • 1/2 cup vegetable oil
  • 2 eggs

Bailey's Ganache

  • 12 ounces semi-sweet chocolate chips
  • 4 ounces Baileys Irish cream
  • 2 ounces heavy cream

Topping

  • 2 tablespoons dark chocolate melting wafers , melted and optional

Instructions

  • Preheat the oven to 350°F. Line a 9x13 baking dish with parchment paper, set aside.
  • Place the brownie mix, Irish cream, oil, and eggs into a large bowl, mix per the directions on the back of the box.
  • Add the batter to the prepared baking dish and smooth out the top. Bake for 22-25 minutes until a toothpick inserted 2 inches from the side comes out clean. Or bake per the directions on the back of the box. Let cool completely.
  • While the brownies are cooling, make the ganache. Place the chocolate chips in a medium-sized heat proof bowl, set aside.
  • Place the Baileys and heavy cream into a small saucepot, stir occasionally until it just comes to a simmer. Pour this over the chocolate chips and cover the bowl. Let sit for 5 minutes.
  • Whisk until smooth. Let the ganache sit at room temperature until it is firm. You can also place it in the fridge for about 1 hour.
  • Place the ganache into a large bowl with an electric hand mixer or the body of a stand mixer with the whisk attachment and whip until it becomes light and fluffy.
  • Lift the brownies out of the baking dish by the parchment paper and spread the ganache evenly over the brownies.
  • Cut into servings, then drizzle with optional melted dark chocolate. Serve.

Notes

These boozy Baileys brownies will last at room temperature in an airtight container for up to 2 days. Due to the ganache, they will need to be refrigerated after 2 days. Then in the fridge they will be good for up to 5 days total.
You can freeze these frosted brownies for up to 3 months. These are best enjoyed at room temperature (no one likes cold brownies!) so allow them to come up to room temp to enjoy any leftovers.
