Ingredients

Brownie Base
1 cup semi-sweet chocolate chips or chopped chocolate
1 cup unsalted butter (softened)
1 1/2 cups granulated sugar
1/2 cup light brown sugar
4 large eggs, room temperature
3/4 cup unsweetened cocoa powder
1 cup all-purpose flour
1 teaspoon vanilla extract
1/2 teaspoon salt
1/3 cup Baileys Irish Cream

Baileys Buttercream Frosting
1 cup unsalted butter, softened
3 cups powdered sugar
3 tablespoons Baileys Irish Cream
1 teaspoon vanilla extract
Optional: 2 tablespoons heavy cream if needed for texture

Chocolate Drizzle
1/2 cup chocolate chips, melted
Optional: chopped chocolate or chocolate flakes for garnish

How to Make Baileys Irish Cream Brownies

Step 1: Prepare Your Pan
Preheat your oven to 350°F (175°C). Line a square 9×9-inch baking pan with parchment paper and lightly spray with nonstick baking spray. This ensures clean edges and easy removal.

Step 2: Melt the Chocolate
In a microwave-safe bowl, heat butter and chocolate in 30-second intervals, stirring between each, until smooth. Allow the mixture to cool slightly.

Step 3: Add the Sugars
Whisk in granulated sugar and brown sugar until fully combined. The mixture should look glossy and thick.

Step 4: Add the Eggs
Add eggs one at a time, whisking thoroughly after each. The secret to fudgy brownies is not over-mixing once the flour goes in but fully incorporating eggs at this stage.

Step 5: Add Flavor and Baileys
Mix in vanilla extract and Baileys Irish Cream. The batter will become silky and aromatic.

Step 6: Add Dry Ingredients
Sift flour, cocoa powder, and salt into the bowl. Gently fold until the batter is just combined — avoid over-mixing to keep brownies tender and fudgy.

Step 7: Bake
Spread the batter evenly into the prepared baking pan. Smooth the top with a spatula.
Bake for about 28 to 33 minutes, or until the center is set but still slightly soft. A toothpick should come out with moist crumbs, not wet batter.

Step 8: Cool Completely
Let the brownies cool in the pan, then transfer them to a cutting board. They must be fully cooled before frosting.

Step 9: Make Baileys Buttercream
Beat softened butter until creamy. Add powdered sugar gradually, mixing on low speed at first.
Pour in Baileys and vanilla extract and continue whipping until the frosting becomes fluffy and smooth. If too thick, add a small amount of heavy cream.

Step 10: Frost and Add Chocolate Drizzle
Spread frosting generously over cooled brownies. Drizzle melted chocolate over the top.
Finish with chopped chocolate pieces for visual appeal and extra texture.

Step 11: Chill and Slice
Refrigerate for 20 minutes before slicing for cleaner edges.

Tips for Best Results

Do not overbake: Remove brownies from the oven while centers are still slightly soft. They firm up as they cool.
Use room temperature ingredients: This helps batter blend smoothly without over-mixing.
Chill before cutting: Makes brownies easier to slice into perfect squares.
Choose quality chocolate: Better chocolate always improves flavor.
Adjust Baileys to taste: Add up to 1/2 cup Baileys for a stronger flavor if desired.

Texture and Flavor Notes

These brownies are fudgy, not cakey. Every bite is moist and intensely chocolaty. The Baileys flavor comes through warmly without feeling too strong or alcoholic.
