How to Make Bailey’s Irish Cream Brownies
-
Prepare the Pan: Preheat your oven to 350°F (175°C). Line a metal cake pan (8×8, 9×9, or 9×13) with parchment paper, leaving some overhang for easy removal later. This ensures your brownies come out seamlessly!
-
Make Brownie Base: In a saucepan over low heat, melt the unsalted butter. Stir in granulated sugar until the mixture is smooth and all ingredients are combined. Cool for a few minutes, then mix in the canola oil and vanilla. Beat in eggs one at a time until fully incorporated.
-
Mix Dry Ingredients: In a separate bowl, sift together the all-purpose flour, Dutch-processed cocoa powder, black cocoa powder (if using), malted milk powder (optional), and salt. Gradually fold this dry mixture into the butter-sugar blend, then gently fold in the chopped chocolate or mini chips until just combined.
-
Bake: Pour the brownie batter into the prepared pan. Bake for 25-30 minutes for a 9×13-inch pan, or 40-45 minutes if using a smaller pan. The brownies should have a firm top and slightly underbaked center. Let cool completely in the pan.
-
Prepare Frosting: In a mixing bowl, beat the softened salted butter until creamy. Gradually add sifted powdered sugar, Irish cream liqueur, and vanilla extract, mixing until the frosting becomes fluffy and smooth.
-
Frost Brownies: Once the brownies are completely cool, evenly spread the Irish cream frosting over the top, allowing some frosting to peek at the edges.
-
Make Ganache: In a bowl, combine the bittersweet chocolate, heavy cream, and Irish cream liqueur. Microwave in short bursts until melted, whisking until smooth. Stir in salted butter for added richness and pour the ganache over the frosted brownies.
-
Set and Slice: Allow the ganache to set at room temperature for at least 30 minutes. Once set, use the parchment overhang to lift brownies out of the pan and slice into bars.
Optional: Garnish with festive sprinkles or crushed nuts on top of the ganache for an extra zing!

Expert Tips for Bailey’s Irish Cream Brownies
- Room Temperature Ingredients: Ensure your butter, eggs, and other ingredients are at room temperature for better incorporation and an airy texture in your brownies.
- Choose Quality Chocolate: Use high-quality bittersweet chocolate to give the ganache and brownie depth of flavor. Chop it finely for even melting.
- Don’t Overmix: Gently fold in the dry ingredients until just combined. Overmixing can lead to tough brownies instead of the desired fudgy texture.
- Cool before Frosting: Let the brownies cool completely before frosting to prevent the icing from melting and losing its shape.
- Chill for Clean Cuts: For neat slices, chill the brownies before cutting or use a hot knife, wiping it with a cloth between cuts for a polished finish.
- Layer Variations: Don’t hesitate to experiment with toppings! Add crushed nuts or festive sprinkles atop the ganache for extra flair on your Bailey’s Irish Cream Brownies.
How to Store and Freeze Bailey’s Irish Cream Brownies
Room Temperature: Keep brownies in an airtight container at room temperature for up to 3 days to maintain their fudgy texture.
Fridge: Store in the fridge for up to 5 days in an airtight container to prolong freshness; just note that chilling may slightly alter the brownie texture.
Freezer: For longer storage, freeze brownies wrapped tightly in plastic wrap and then in foil for up to 3 months. Cut into bars before freezing for easy access.
Reheating: To enjoy at room temperature after freezing, let brownies thaw in the fridge overnight before serving. For a warm treat, heat them briefly in the microwave for 10-15 seconds.

This way, you can easily slice and serve your decadent dessert with minimal effort, ensuring they remain just as delicious as the day they were made!
