Irish Dessert Blonde Brownies

Irish Dessert Blonde Brownie recipe with a twist!

Blonde Brownies are one of my favorite treats. What makes this brownie recipe an Irish dessert is the addition of Irish Whiskey in the glaze.

You’re welcome. ๐Ÿ˜‰

This recipe was given to me by a friend a few years ago. The original recipe calls for a few tablespoons of freshly ground coffee in the mix. I do not like coffee-flavored anything, so I omit that ingredient when I make it for myself. Without it, it’s more of a basic blonde brownie recipe.

I’m sure if you like coffee flavor, it would taste amazing combined with the hint of Irish whiskey in the icing glaze.

St. Patrick’s Day is one of my favorite holidays but other than Irish soda bread, Irish dessert choices are pretty limited. I have a sweet tooth, so this rich brownie recipe is my preferred dessert.

Making the Blonde Brownies

This blonde brownie recipe is topped with sliced almonds giving it another layer of flavor. If anyone has nut allergies, that can also be omitted. The recipe is easily customizable in general. My oldest daughter and I are both rather picky eaters so most recipes I make whether dinner or dessert are usually things I can easily change up.

I have a divided baking pan I use just for brownies. The reason for that is, when they’re done you don’t have to cut them up. The pan is designed to give you perfectly cut brownies. If you use one of those, be sure to grease it well. The blonde brownies are a bit stickier than regular brownies are. I grease mine with Pam Spray so it gets into all the corners of the pan.

Here is how it looked before going into the oven.

How To Make The Irish Glaze

After the brownies are cooled off and removed from the pan, it’s time to make the icing. It only takes three ingredients to make the glaze. I bought a tiny bottle of Irish whiskey because I only needed it for this recipe.

Though the recipe calls for 3/4 cup of the confectioner’s sugar, add it a little at a time. You may not need all of it. The consistency should be thick but not so thick that you can’t pour it.

You can use a spoon to drizzle it on or put it into a pastry bag with a small round tip. I used the pasty bag for these.

Pour the glaze on the brownies in a criss-cross pattern and be generous with it, there’s whiskey in there. ๐Ÿ˜‰

Vanilla ice cream would make an amazing topping on these as well. You could use that in place of the glaze if desired. A warm caramel topping would be delicious drizzled over vanilla ice cream. As I mentioned, these are easily customized to your preferences.

My husband isn’t a big cake or brownie eater, but after tasting one of these he had a second.
