Chocolatey, rich, and delicious – these Crinkle-Top Cookies split at the top, creating a crunchy top that looks good, and tastes good.
Using a bain-marie, melt 150g dark chocolate and set aside until cool to touch.
In a separate bowl, beat butter and 100g sugar until crumbly. Fold in whisked egg whites and mix well. To the mixture, mix vanilla extract and melted chocolate.
Using the Kenwood Titanium XL Mixer with the balloon whisk attachment, mix flour, baking powder and salt. Gradually add in butter and water. Add in chocolate mixture and mix well.
