Preheat your oven to 190ºC/180ºC Fan/375ºF and line two baking trays with parchment paper and leave to the side.
Mix together the unsalted butter and both granulated and light brown sugars until light and fluffy and thoroughly combined.
Add the vanilla bean extract and the beaten egg, and mix again briefly.
Add the cocoa powder, self raising flour, bicarbonate of soda, baking powder and sea salt and mix until a thick paste/cookie dough is formed.
Fold through the chopped up Toblerone and either the 50g chopped almonds OR extra 50g chocolate chips.
Using a cookie scoop, scoop the mixture onto the trays and make sure they are suitable spread out so they stay separate! (I usually fit 6 on each tray to be safe.)
Bake in the oven for 10-12 minutes.
Once baked, remove from the oven and allow to cool for a couple of minutes, then transfer to a wire rack to cool completely.
Notes
I say to use chopped almonds OR extra chocolate chips as you want 250g of filling as a whole (Like my Terry’s Chocolate Orange Cookies) - you can of course use 250g of Toblerone, but as Toblerone is made out of Nougat, which is almonds, I tend to add in some chopped almonds as I like the difference.
You can also use dark/milk/white Toblerone, it doesn't really matter, its a choice of preference!
These will last in an airtight container, at room temperature for 5 days, or you can freeze the portioned raw dough for up to 3 months!
