We put a flavorful spin on a classic warm weather treat with this easy Irish Cream Hot Fudge Sauce recipe. Adding the rich flavor of Kerrygold Irish Cream Liqueur gives this hot fudge sauce an indulgent twist that you’ll be craving all summer long!

Making homemade hot fudge sauce couldn’t be easier. I love that this recipe uses real chocolate, cocoa powder AND Irish Cream Liqueur for a triple punch of chocolate flavor. I’m a dark chocolate lover, so bittersweet chocolate is the only way I roll with this recipe, but feel free to swap in semi-sweet chocolate if you’re craving a sweeter sauce. The hardest part of making this hot fudge sauce recipe is waiting for it to be cool enough to eat!

What is the difference between hot fudge sauce and chocolate syrup?

Let’s start with the obvious: hot fudge is thicker than chocolate syrup. The ingredients in hot fudge are often more decadent resulting in a richer, more flavorful sauce. You have to warm up fudge sauce to get it to pour nicely while chocolate syrup pours easily whether warm or cold.

How else can I use Irish Cream Hot Fudge Sauce?

Besides the deliciously obvious choice (ice cream sundaes), I wouldn’t hesitate to pour this decadent sauce over cheesecake, bread pudding or even drizzle it over this vanilla bean panna cotta. It makes a pretty mean milkshake, too.
