How to Make Irish Whiskey Brownies Recipe
Step 1: Prep Your Pan
Begin by heating your oven to 350 degrees Fahrenheit and lining a 9×9 inch brownie pan with parchment paper. This step makes sure your brownies won’t stick and releases easily, so you keep those beautiful edges intact.
Step 2: Mix Your Brownie Batter
In a standing mixer, blend the fudge brownie mix, water, canola oil, and eggs until everything is smooth and fully combined. The mix will be velvety and ready to transform into that rich base we all crave.
Step 3: Bake to Perfection
Pour the batter evenly into your prepared pan and bake according to the time recommended on the box, typically about 25 minutes. Keep an eye on them—a toothpick should come out with only a few moist crumbs for ideal fudginess.
Step 4: Cool Your Brownies
Once baked, set your brownies aside to cool completely before moving on to frosting. This step ensures the frosting spreads smoothly and that every bite holds together beautifully.
Step 5: Make the Irish Whiskey Frosting
Start by melting the unsweetened chocolate and butter together in a small saucepan over low heat or in short bursts in the microwave, whisking until smooth and glossy.
Step 6: Combine Frosting Ingredients
In a medium bowl, use an electric mixer to combine powdered sugar, half and half, Irish whiskey, and vanilla extract until fluffy and creamy. Then gradually add the melted chocolate and butter mixture, beating until everything is silky and fully incorporated.
Step 7: Frost and Finish
Spread your luscious Irish whiskey frosting generously over the cooled brownies, smoothing it out with a spatula for an even, decadent layer. Then cut into squares and get ready to enjoy!
