Katherine Sabbath’s Caramel Party Slice Recipe

This recipe is from our teacher turned cake extraordinaire, Katherine Sabbath! Thanks for sharing this with us, Katherine!

This was one of the very first recipes I learned when I started baking in high school, and I adapted it from one of my Mother’s cookbooks. It’s pretty easy to make but it became an instant hit with my friends! It’s still requested whenever I attend parties today, because it’s just so crunchy, chewy, chocolatey, and delicious! It’s my favourite caramel slice recipe and I hope it becomes yours too!
