All Costco’s Kirkland brand drinks seem to be great- the wines, the liquors, and now… how about this Irish Cream Liqueur? Into the cart it went since I couldn’t pass up the possibility of a good drink.
We have since tried it, and the Kirkland Irish Cream Liqueur is a winner! On ice and in coffee, The Husband and I have loved it. The Bunco Club has indulged and gave their approval, but the level in the bottle has still barely dropped.What am I supposed to do with an enormous bottle? It’s time to experiment because this is a seriously ridiculous amount of booze…
How about brownies? Yum.

Irish Cream Liqueur Brownies
Oven at 350. Grease a 9″ x 13″ baking pan.
Into a large bowl put:
- The brownie mix
Mix together in a small bowl or measuring cup:
- 1/4 cup Irish Cream Liqueur instead of water (or amount of liquid as directed by recipe)
- 1 teaspoon vanilla
- 1 Tablespoon instant coffee crystals
Beat together in a medium bowl:
- 1/2 cup vegetable oil (or as directed)
- 2 eggs (ditto)
Stir together the liqueur and egg mixes, then slowly add all the liquid mix into the large bowl with the instant brownie mix. Add in chocolate chips now, if you are using them in your recipe. Stir until combined, but don’t over mix.
Pour batter into prepared pan. Follow your usual baking directions, and in about 25 minutes you should be in Brownie Bliss!
I need about a half gallon of milk right now, or maybe a big mug of black coffee… or two. I just tasted my brownie concoction and WOW. Very sweet, but Very good. I think that the brownie mix could have stood another tablespoon or two of liqueur, as the batter was not only more stiff than when usually made with water, but also- the Irish Cream Liqueur flavor is pretty mild.
Irish Cream Liqueur Icing (makes about 1 1/2 cups icing)
- In bowl of stand mixer, slowly beat together one cube of butter, two ounces cream cheese(1/4 of an 8 oz. block) and two cups powdered sugar. Beat on high speed for three to four minutes until light and fluffy.
- Stop the mixer and add one teaspoon vanilla and 1/4 cup Irish Cream Liqueur. Mix again, on low speed until combined, then high again for one to two minutes.
My Baking Notes:
-I used my family’s favorite boxed mix as a base and added my not-so-secret ingredients (instant coffee, vanilla, and chocolate chips). Remember, if you are going to use instant coffee crystals to punch up the chocolate flavor, you must add the dry coffee to the water/vanilla/liqueur and NOT directly into the batter, or they won’t dissolve.
-If you mix together all your liquids before stirring them into the brownie mix, you are much less likely to over mix the batter.
Bonus Tip!!
Ever hear that if you slice your brownies with a plastic knife, that they will slice more evenly and not get all ragged? Well, it is true.


Yep. It works, slice up your brownies with a plastic knife from now on, everyone!
