TIPS AND TRICKS ON MAKING GUINNESS CHOCOLATE BUTTERCREAM FROSTING:
- Make sure the butter is softened to room temperature (not melted.) Be sure to mix the butter until light and fluffy before adding in any other ingredients, this helps everything combine better with out lumps.
- This frosting is very smooth and creamy but holds its shape when piping as well.
- If you plan on piping right away, allow the frosting to cool slightly in the refrigerator before piping.
- Not a fan of Guinness? You can use milk or cream as a replacement.
- I used semi-sweet chocolate chips for this recipe, I feel like it matches the flavor of the Guinness the best, but you can use milk chocolate in a pinch.
- Make sure to let the chocolate cool before adding it to the butter mixture or it will make everything too warm.
- I microwave the chocolate chips until smooth, but you can also use a double boiler to ensure it won't seize up.
- This recipe makes enough to frost one cake.
- Try using this frosting to make my Guinness Cake Ball recipe.

You did a fantastic job of icing your cake! Looks very nice. I have a question - when you say this makes enough for "one cake", how big of a cake? I am assuming you mean a layer cake (as pictured) but am curious about the size of pan you used. Any idea how many cups of icing your recipe yielded? Thanks much!
