You Must Know

This dessert was the first thing my daughter made completely on her own and she served it with pride at her birthday sleepover where every piece disappeared in minutes

Storage Tips

Store cut squares in a container lined with parchment paper between layers to avoid sticking. They last well for up to one week refrigerated or up to three months in the freezer wrapped tightly.

Ingredient Substitutions

Use any chocolate cream filled biscuits in place of Bourbon types for a fun variation. Chocolate digestives work well too especially if you prefer a less sweet finish.

Serving Suggestions

Serve chilled with a hot drink or cut smaller squares to offer with tea for a more refined bite. These make a great finish to casual dinners with friends.
