Top o’ the morning to ya! Isn’t that we’re “supposed” to say as it nears St. Patrick’s Day? Today I want to share an absolutely scrumptious recipe for Irish Cream Layered Brownies. Thee brownies are made of three distinct layers: a mocha brownie, topped with an Irish Cream frosting, which is topped with Irish cream chocolate ganache.

Yes… you might detect an “Irish” theme here. One of our sons gave me a cookbook for Christmas to add to my collection. I found this recipe for these sweet treats in it, and we were thrilled with the results! Perfect for St. Patrick’s Day or any time you want a yummy dessert to serve, I’m confident you’re gonna enjoy them. These brownies are chewy and full of flavor, and I can guarantee you no leprechauns were harmed in the making of this recipe.

Irish cream liqueur is used (sparingly, but it’s in there) to flavor the frosting and the chocolate ganache, giving it a distinctive flavor.  The recipe, as written below will yield 16 delicious Irish Cream Layered Brownies. Here’s how to make them:

Make The Brownie Batter

Before mixing the batter, preheat your oven to 350°F and grease the bottom and sides of an 8″ x 8″ square baking pan. Set the pan aside while you make the brownie batter. To make the batter, first sift flour, baking powder and salt into a mixing bowl, then set the bowl aside. 

Flour, baking powder and salt are sifted together for the brownie batter.

Melt butter in a small saucepan on low heat, then remove the pan from the heat source. Immediately stir in cocoa, oil, and instant coffee powder. Stir well, to combine, then let the mixture cool a bit (4-5 minutes).

After it’s cooled, stir in granulated sugar, then beaten eggs, stirring well as the eggs are added. Add the flour mixture and vanilla extract, adding the flour mixture a little at a time. Stir well, between additions, to incorporate the dry ingredients into the batter.

Layer #1- Bake The Brownies

Spread the brownie batter evenly into the prepared baking pan. Bake at 350°F. for 23-25 minutes, or until the center is set, being careful to NOT overcook the brownies. Test by inserting a toothpick into the top center of the brownies. It should come out free of batter. Transfer the pan to a wire rack to cool until the brownies are just barely warm.

Brownies are baked in a greased 8"x8" pan until set on top.

Layer #2- Make The Irish Cream Frosting

While the brownies cool, mix together the Irish cream frosting. Beat powdered sugar and softened butter together with an electric mixer on Low setting. Add Irish cream liqueur, and beat the frosting until it becomes smooth.

Spread the frosting over the entire surface of the slightly warm brownies (if they’re too hot, it will melt frosting). Place the pan in a refrigerator and let the chill for 1 hour. This allows the frosting to firm up before adding the top layer of ganache.

Irish cream flavored frosting is mixed together, then spread on cooled brownies.

Layer #3- Make The Chocolate Ganache Topping

About 15 minutes before the brownies finish chilling, make the chocolate ganache topping. Place chocolate chips, Irish cream liqueur, heavy whipping cream and instant coffee powder in a microwave-safe bowl.

Microwave on High temperature for 1 minute, then stir. Place bowl back into the microwave, and heat it on High another 30-45 seconds. Remove and stir the ganache until smooth. Let the ganache cool slightly (3-4 minutes), or until it is warm and spreadable.

Spread the ganache evenly over the entire frosting layer. By the way… the photo below is the same ganache. Different lighting, perhaps? Weird! Cover the pan with plastic wrap, and refrigerate the Irish Cream Layered Brownies until the chocolate is firmly set. This usually takes about an hour or less.

The Irish Cream Layered Brownies Are Ready To Eat!

After the Irish Cream Layered Brownies have been fully chilled, they’re ready to cut, serve, and enjoy! Cut the brownies into 16 pieces, and dig in. They taste wonderful! Store any leftovers covered in the fridge, or give some to friends and family. We gave extra Irish Cream Layered Brownies to both of our sons so they could enjoy them, too!

The brownies have a light mocha taste, and are chewy and yummy. Those two layers of frosting and ganache will taste awesome, thanks to the Irish cream liqueur infused flavor. Put all three layers together and you’ve got terrific dessert treats for St. Patrick’s Day OR any other day, for that matter! They are dense, rich tasting and oh so good!

I really hope you will give these delicious fudgy brownies a try. Remember to plan ahead, to allow for chilling two of the three layers, okay? Thanks for stopping by, and I hope you’ll come back soon for more yummy recipes. Take care, and have a wonderful day.
