    Steps to Make Baileys Buttercream Frosting

    1. Break the white chocolate into small pieces and place in a small microwave-proof bowl. Heat in the microwave for one minute at 50% power, stirring after heating. Then, continue to heat for 30-second increments at 50% powder, stirring after each heating, until the chocolate is melted and smooth. Set the bowl aside to cool slightly until ready to add to the frosting.

    Ingredients for Jameson Irish Whiskey Salted Caramel Glaze

    Steps to Make Jameson Irish Whiskey Salted Caramel Glaze

    1. Place a medium-sized saucepan with high sides over medium-low heat. Add the sugar and water. Cook, stirring occasionally with a silicone spatula, until the sugar has fully dissolved, about 5 minutes.
    combining water and sugar for glaze
    1. Add the cold cubed butter, but do not stir it. Bring the mixture to a boil over medium heat. Continue cooking the mixture without stirring until it turns a deep golden brown/copper color, about 10 to 14 minutes. Make sure to keep an eye on it so that it does not burn.
    adding butter to syrup for glaze
    1. Once the desired color is reached, remove the caramel from the heat and immediately and carefully whisk in the heavy whipping cream and Jameson Irish Whiskey. At this point, the mixture will hiss and bubble aggressively.
    adding cream for glaze
    1. Add the vanilla extract and salt. Whisk the mixture continuously and vigorously until smooth. Set aside and allow it to come to room temperature. Once it comes to room temperature, place uncovered in the refrigerator for at least four hours so it will thicken. The thicker the glaze, the less likely it is to run down the sides of the cake and pool around the bottom.

    1. Remove the cake and the glaze from the refrigerator. Spoon the glaze over the cold cake.

    Recipe Tips and Tricks

    • Take care not to spray too much non-stick cooking spray with flour in the pan; if you do, it could mix with the cake batter.
    • When making the glaze, once you've added the butter to the syrup in the saucepan, resist the urge to stir! Stirring after this point will cause the glaze to seize up and not form properly.
    • It is essential to refrigerate both the frosted cake and the glaze before adding the glaze to the cake. Chilling the glaze will help to thicken it. The thicker the glaze, the less likely it is to run down the sides of the cake and pool around the bottom. The cake being the same temperature as the glaze will also help prevent the glaze from pooling.
    • This recipe calls for minimal amounts of alcohol. If Baileys and Jameson are not something you keep on hand, I recommend buying the small "airplane" size bottles. Those bottles contain 50ml, which is just over three tablespoons. As far as the Guinness, I would recommend buying a single can or bottle if you can find it. A good place to check is a convenience store. If you can't find Guinness any stout will do.
