  1. Looks amazing- my hubby would love these!

  2. These are like Christmas in a baked good. I love them and will be definitely making and freezing some this Christmas season.

  3. Those look refreshing yet decadent all at the same time and your photos of these bars are perfect, clean and gorgeous as if you have been trained in food photography. This dessert speaks to me loud and clear as I think mint and chocolate is a mix made in heaven. Whenever I get ice cream, it’s hard for me NOT to get mint chocolate chip!

    Can you please clarify the amount of powdered sugar in the frosting? I see that originally you mix butter with 1 3/4 cup. I cannot see that i add any more. The recipe calls for 3 1/2cups. Am i missing something?

  15. Kitty says:

    These do look excellent, ta! One question. How long should the 12 oz of white chocolate and butter cool before whisking in the sugar, eggs, vanilla, and peppermint extract? Or do you temper so the eggs won’t ‘curdle’/start cooking?

  16. Jennifer says:

    Confused about how much powdered sugar goes into the frosting…3-1/2 or 1-3/4cups?

  17. Colleen says:

    Thank you for the lovely recipe! I made these for an office holiday potluck today and they were a hit! Many colleagues telling each other, “You’ve got to try one of those!”

  18. Lizzy says:

    I just made these and they are cooling but smell absolutely delicious! The print of recipe doesn’t say to add the rest of the powdered sugar though, just a heads up(: I can’t wait to try them!(:
