Ingredients
Brownie Layer
- 1 cup unsalted butter
- 8 oz semi-sweet chocolate, chopped
- 2 cups white sugar
- 4 large eggs
- 2 tsp vanilla extract
- 3/4 cup cocoa powder
- 3/4 cup all-purpose flour
- 1/2 tsp salt
Baileys Buttercream
- 2/3 cup unsalted butter, softened
- 2 1/2 cups powdered sugar
- 3–4 tbsp Baileys Irish Cream
Baileys Chocolate Ganache
- 8 oz semi-sweet chocolate, finely chopped
- 1/2 cup Baileys Irish Cream
Instructions
1. Prepare the Brownies
- Preheat oven to 350°F (180°C). Line a 9×13-inch pan with parchment paper, leaving overhang for easy removal.
- Melt butter and chopped chocolate together in a heatproof bowl (microwave in 1-minute intervals, stirring until smooth).
- Whisk in sugar, then eggs one at a time, followed by vanilla extract.
- Gently fold in cocoa powder, flour, and salt.
- Pour batter into prepared pan and bake 32–37 minutes, or until a toothpick comes out clean or with a few moist crumbs. Cool completely.
2. Make the Baileys Frosting
- Beat softened butter in a large bowl until smooth.
- Gradually add powdered sugar and Baileys, alternating until desired sweetness and consistency is reached.
- Frost cooled brownies evenly, smoothing the top. Chill in the fridge for 20 minutes to firm the frosting.
3. Prepare the Baileys Ganache
- Place chopped chocolate in a heatproof bowl.
- Heat Baileys in the microwave until almost boiling, then pour over chocolate. Let sit 2 minutes, then whisk until smooth.
- Pour ganache over frosted brownies, spreading evenly. Refrigerate until firm.
4. Slice and Serve
- Remove brownies from pan using parchment overhang. Slice with a sharp knife while cold for clean edges.
Tips & Notes
- Can be made in a 9×9 pan (halve recipe).
- Box mix brownies work perfectly; just add Baileys frosting and ganache.
- Semi-sweet chocolate can be replaced with 50–70% dark chocolate. Avoid bittersweet chocolate.
- Store in an airtight container in the fridge for up to 5 days.
