Ingredients
For the Chocolate Brownies
- 1 cup unsalted butter
- 8 oz semi-sweet chocolate, chopped
- 1 cup granulated sugar
- ½ cup brown sugar, packed
- 3 large eggs
- 1 teaspoon vanilla extract
- ¼ cup Irish cream liqueur
- ¾ cup all-purpose flour
- ½ cup unsweetened cocoa powder
- ½ teaspoon salt
For the Creamy Irish Cream Frosting
- ½ cup unsalted butter, softened
- 3 cups powdered sugar
- 3 tablespoons Irish cream liqueur
- 1–2 tablespoons heavy cream (as needed)
- 1 teaspoon vanilla extract
- Pinch of salt
Optional garnish: cocoa powder, chocolate curls, or chocolate shavings.

Instructions
1. Prepare Your Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the sides for easy removal. Lightly grease the parchment.
2. Melt the Chocolate and Butter
In a heatproof bowl set over a pot of simmering water (double boiler method), melt the butter and chopped semi-sweet chocolate together. Stir until smooth and glossy. Remove from heat and allow to cool slightly.
3. Combine Sugars
Whisk the granulated sugar and brown sugar into the melted chocolate mixture. Stir until fully incorporated.
4. Add Eggs and Flavorings
Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract and Irish cream liqueur. The batter should look smooth and slightly thick.
5. Mix Dry Ingredients
In a separate bowl, whisk together flour, cocoa powder, and salt.
6. Combine Wet and Dry
Gently fold the dry ingredients into the chocolate mixture using a spatula. Mix just until combined—do not overmix.
7. Bake
Pour the batter into the prepared pan and spread evenly. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter).
Allow brownies to cool completely in the pan before frosting.

8. Beat the Butter
In a large mixing bowl, beat the softened butter until light and fluffy, about 2–3 minutes.
9. Add Powdered Sugar
Gradually add powdered sugar, mixing on low speed until combined.
10. Add Irish Cream and Flavorings
Pour in Irish cream liqueur, vanilla extract, salt, and 1 tablespoon heavy cream. Beat on medium-high speed until smooth and fluffy. Add additional cream if needed to reach a spreadable consistency.
11. Frost the Brownies
Once brownies are completely cooled, spread frosting evenly over the top using an offset spatula. Swirl for a decorative finish.
12. Garnish and Slice
Dust lightly with cocoa powder or add chocolate curls. Lift brownies out using parchment overhang and cut into squares.
What Makes These Brownies Extra Fudgy?
The secret lies in:
- Melted chocolate (not just cocoa powder)
- Higher fat-to-flour ratio
- Brown sugar for moisture
- Slightly underbaking for a dense center
Irish cream adds moisture and enhances chocolate richness without thinning the batter too much.
Tips for Perfect Baileys Brownies
Don’t Overbake:
Remove brownies when the center is slightly soft. They continue setting as they cool.
Cool Completely Before Frosting:
Warm brownies will melt the frosting.
Use Room Temperature Ingredients:
This ensures a smooth batter and fluffy frosting.
Chill Before Cutting:
For super clean slices, refrigerate frosted brownies for 30 minutes before slicing.
Variations to Try
Dark Chocolate Lovers
Use bittersweet chocolate instead of semi-sweet for deeper intensity.
Espresso Kick
Add 1 teaspoon espresso powder to the batter to enhance chocolate flavor.
Nutty Twist
Fold in ½ cup chopped walnuts or pecans for texture.
Salted Caramel Baileys Brownies
Drizzle caramel sauce over frosting and sprinkle with flaky sea salt.
Serving Suggestions
- Pair with hot coffee or espresso
- Serve alongside vanilla bean ice cream
- Add fresh berries for contrast
- Present on a dessert platter for parties
These brownies also make beautiful edible gifts when wrapped in parchment and tied with ribbon.
Storage Instructions
Store brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 5 days.
To freeze, wrap unfrosted brownies tightly in plastic wrap and freeze for up to 2 months. Thaw at room temperature and frost before serving.
Frequently Asked Questions
Can I make these without alcohol?
Yes. Substitute Irish cream with heavy cream plus ½ teaspoon coffee extract.
Do they taste strongly of alcohol?
No. The flavor is subtle and creamy, enhancing the chocolate rather than overpowering it.
Can I make them ahead of time?
Absolutely. They actually taste even better the next day as flavors develop.

The Magic of Irish Cream in Baking
Irish cream liqueur blends cream, cocoa, and whiskey flavors into one smooth ingredient. In baking, it deepens chocolate flavor and adds complexity. The alcohol content largely bakes off, leaving behind its signature richness.
These Baileys brownies are the perfect example of how a splash of liqueur can transform a classic dessert into something extraordinary.
