Preparation Phase & Tools to Use
Before you begin crafting these delectable Baileys brownies, it’s essential to prepare your kitchen for a smooth baking experience. Start by preheating your oven to 350°F (180°C) to ensure optimal baking conditions. Grab a 9×13-inch baking pan and line it with parchment paper, leaving some overhang on the sides to assist in the brownie removal after baking.
For the preparations, you’ll need a few crucial tools: a heatproof mixing bowl, a whisk, a spatula, and an electric mixer. A microwave is also handy for melting the butter and chocolate. Having these tools ready will streamline your process and help you easily make this delicious dessert.

Ingredients
- 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
- 2/3 cup unsalted butter, softened (for frosting)
- 2 1/2 cups powdered sugar
- 3–4 tbsp Baileys Irish Cream
- 8 oz semi-sweet chocolate, finely chopped (for ganache)
- 1/2 cup Baileys Irish Cream (for ganache)
Instructions
Step 1: Prepare the Brownies
Start by preheating your oven to 350°F (180°C) and prepare your baking pan. Line a 9×13-inch pan with parchment paper, allowing some overhang on the sides for easier removal later. Next, melt the butter and chopped chocolate together in a heatproof bowl. This can be done using a microwave, heating in one-minute intervals, stirring until smooth.
Once melted, add the sugar directly into the bowl, whisking until well combined. Then, beat in the eggs one at a time, following up with the vanilla extract. It’s important to fold in the dry ingredients gently—cocoa powder, flour, and salt—ensuring not to overmix the batter. Finally, pour the batter into the lined pan, and bake for 32–37 minutes. You’ll know they’re done when a toothpick inserted comes out clean or with just a few moist crumbs. Allow these to cool completely.
Step 2: Make the Baileys Frosting
Once the brownies are completely cool, it’s time to whip up the delicious Baileys frosting. Start by beating the softened butter in a mixing bowl until it becomes smooth and creamy. Gradually incorporate the powdered sugar, alternating with 3 to 4 tablespoons of Baileys Irish Cream. This gradual addition will help achieve a perfectly sweet and creamy frosting. Adjust the amount of Baileys to suit your preference for flavor and consistency.
Once the frosting is well-mixed and has reached the desired consistency, spread it generously over the cooled brownies, smoothing the top for a neat finish. For best results, chill the frosted brownies in the refrigerator for about 20 minutes to firm up the frosting.
Step 3: Prepare the Baileys Ganache
While the frosting sets, you can prepare the Baileys ganache. Place the chopped semi-sweet chocolate in another heatproof bowl. Heat the Baileys in the microwave until it’s almost boiling, then pour it over the chocolate. Allow it to sit for about two minutes before whisking until it becomes smooth and glossy. Pour this luscious ganache over the frosted brownies, ensuring an even spread across the surface. Refrigerate the entire pan until the ganache is firm.
Step 4: Slice and Serve
Once everything has set, use the parchment overhang to lift the brownies out of the pan. Place them on a cutting board, and using a sharp knife, slice them into squares. It’s best to slice while they’re cold for optimal clean edges. Now you’re ready to enjoy the decadence of your Baileys brownies!

Variations
- Protein: Add some chopped nuts like walnuts or pecans for a crunchy texture, or include a layer of chocolate chips for extra chocolate flavor.
- Vegetables: For a healthier twist, consider adding some pureed avocado in the brownie mix to enhance moisture and richness without the added fats.
- Spices: Enhance the flavor by adding a pinch of espresso powder to deepen the chocolate notes or a dash of cinnamon for warmth.
Cooking Notes
- Ensure all your ingredients are at room temperature for the best mixing results.
- Be cautious not to overbake the brownies; keeping them slightly underdone will enhance their fudginess.
- Let the brownies cool thoroughly for a clean slicing experience.

Serving Suggestions

- Pair with a scoop of vanilla ice cream to balance the richness of the brownies.
- Present with a drizzle of extra Baileys ganache on top for an elevated dessert experience.
Tips
- For a unique twist, try substituting the Baileys with another Irish cream or flavored liqueur that you enjoy.
- Chilling the brownies will enhance their flavors and make them much easier to cut.
- Use a sharp knife dipped in hot water to cut even cleaner slices.
- These brownies can also be frozen for later enjoyment—just thaw before serving.
