Ingredients You’ll Need
This recipe uses simple, high-quality ingredients to achieve its incredible flavor and texture. Here’s what you’ll need to gather.
For the Fudgy Brownies
- Unsalted Butter: The foundation for that rich, fudgy texture.
- Granulated Sugar: Provides sweetness and contributes to the classic crackly top.
- Unsweetened Chocolate: Using a quality baking chocolate bar creates a much deeper flavor than cocoa powder alone.
- Eggs: They bind the ingredients and add richness.
- All-Purpose Flour: Just enough to give the brownies structure without making them cakey.
- Vanilla Extract: Enhances the chocolate flavor.
- Salt: A crucial ingredient to balance the sweetness.
For the Silky Baileys Buttercream
- Unsalted Butter: Make sure it’s softened to room temperature for the creamiest texture.
- Powdered Sugar: Sift it to avoid any lumps in your frosting.
- Baileys Irish Cream: The star of the show! It adds a unique, creamy, and slightly boozy flavor.
- Cocoa Powder: A touch of cocoa powder adds depth and complements the Irish cream.
- Heavy Cream: Helps to achieve the perfect spreadable consistency.
Step-by-Step Instructions
Follow these simple steps to create the most decadent Baileys Buttercream Brownies you’ve ever tasted.
Step 1: Make the Brownie Batter
First, preheat your oven to 350°F (175°C). Grease an 8×8 inch baking pan and line it with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. In a medium saucepan, melt the butter and unsweetened chocolate over low heat, stirring frequently until smooth. Remove from heat and let it cool slightly.
Next, whisk in the granulated sugar until well combined. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract. Finally, gently fold in the all-purpose flour and salt until just combined. Be careful not to overmix!
Step 2: Bake and Cool the Brownies
Pour the batter into your prepared pan and spread it into an even layer. Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs attached, but not wet batter. Let the brownies cool completely in the pan on a wire rack. This step is crucial; frosting warm brownies will result in a melted mess.
Step 3: Prepare the Baileys Buttercream
While the brownies cool, prepare the frosting. In a large bowl, use an electric mixer to beat the softened butter on medium-high speed until it’s light and fluffy, about 3-4 minutes. Gradually add the sifted powdered sugar and cocoa powder, mixing on low speed until combined, then increase to medium-high and beat for another 2-3 minutes until smooth.
Add the Baileys Irish Cream and heavy cream to the bowl. Start on low speed to incorporate, then beat on medium-high for another 2 minutes until the frosting is light, airy, and spreadable. For another festive treat, check out our No-Bake Gingerbread Cheesecake.
Step 4: Frost and Chill
Once the brownies are completely cool, spread the Baileys buttercream evenly over the top. For clean slices, it’s essential to chill the brownies. Place the frosted brownies in the refrigerator for at least 30 minutes to allow the frosting to set. Once chilled, use the parchment paper overhangs to lift the brownies out of the pan, slice, and serve.
Pro Tips for the Perfect Baileys Brownies
- Don’t Overbake the Brownies: For that perfect fudgy center, it’s better to slightly underbake than overbake. The brownies will continue to set as they cool.
- Use Room Temperature Ingredients: For both the brownies and the buttercream, using room temperature eggs and softened butter ensures everything combines smoothly.
- Quality Matters: Use a high-quality unsweetened chocolate bar and Baileys Irish Cream for the best possible flavor. The difference is noticeable!
- Chill Before Cutting: We can’t stress this enough! Chilling the frosted brownies is the secret to getting clean, professional-looking squares.
Recipe Variations
While this recipe is fantastic as is, feel free to get creative! Here are a few ideas:
- Add Chocolate Chips: Fold 1 cup of semi-sweet or dark chocolate chips into the brownie batter for extra chocolatey goodness.
- Espresso Powder: Add 1 teaspoon of espresso powder to the brownie batter to intensify the chocolate flavor.
- Garnish: Sprinkle some chocolate shavings or a dusting of cocoa powder over the finished frosting for an elegant touch. For another easy dessert, try these Peanut Butter Marshmallow Squares.
Storing Your Brownies
Because of the buttercream frosting, these brownies should be stored in an airtight container in the refrigerator. They will stay fresh and delicious for up to 5 days. For the best texture, let them sit at room temperature for about 15-20 minutes before serving.
Frequently Asked Questions about Baileys Buttercream Brownies
Absolutely! These brownies are a great make-ahead dessert. You can bake the brownies a day in advance, let them cool, and store them covered at room temperature. Prepare the frosting and assemble the day you plan to serve them for the best results.
This recipe calls for unsweetened baking chocolate for a deep, rich flavor that balances the sweet frosting. You could substitute semi-sweet chocolate, but be aware that it will result in a sweeter brownie base.
For fudgy brownies, you want to pull them from the oven when a wooden skewer or toothpick inserted into the center comes out with moist, sticky crumbs attached. If it comes out clean, they are overbaked. If it comes out with wet batter, they need a few more minutes.
If your buttercream seems too runny, the most common cause is butter that was too soft. You can fix this by chilling the frosting for 15-20 minutes. If it’s still too thin, you can beat in a little more sifted powdered sugar, 1 tablespoon at a time, until it reaches the desired consistency.
No. The amount of alcohol in a single serving is very minimal. While the frosting isn’t baked, the quantity of Baileys is distributed across the entire batch, making the alcohol content per brownie negligible.
