Cashew Butterscotch Bars

Last year when I did the first series of 24 Days of Christmas Baking, I shared many of the baked sweets that I make year after year. Midway through, I realized that I didn’t want to use all my favourite treats in the first year. I decided to save a few for this year. So, here is the first one! Cashew Butterscotch Bars just sound amazing, don’t they!! I have made these bars for the past 10 years and they are, by far, the most popular cookie or square I make over the holidays. These are the first to disappear on a tray of Christmas baking and I always need to make sure I grab one or I will miss out. Some years, I make a double batch of them, so that we will have enough for everyone to enjoy. I encourage you to give these ones a try, you will love them!!

    Wow! I made these for the first time yesterday. I followed your recipe and method exactly. Really enjoyed making the butterscotch, it was very satisfying to watch it come together. The results are so good. And they may even be tastier today, because it feels like the soft butterscotch/caramel filling is slightly moistening the shortbread base. My husband loves them, and I will be making them again. Thank you for another amazing recipe.
