Use gingerbread cookies for this rocky road. Do not use a gingerbread loaf/bread/cake. Try making your own using this homemade Gingerbread Cookie recipe. They’re also known as gingerbread snaps. If you want to fasten up the process, purchase a packet of gingerbread cookies from the supermarket, just be sure it is 200 grams, as that is how much is needed for this recipe.
