Add the butter and sugars to a bowl and beat until creamy
Add in the egg, and beat again. If using vanilla, add it in now
Add in the plain flour, baking powder, bicarbonate of soda, and salt and beat until a cookie dough is formed
Add in the kinder chocolate and beat until it is distributed well
Weigh the cookies out into twelve cookie dough balls - they are about 80g each
Once they are rolled into balls, put the cookie dough in the freezer for at least 30 minutes, or in the fridge for an hour or so
Whilst the cookie dough is chilling, preheat your oven to 180C Fan, or 200C regular! If your oven runs hot, go for 160C-170c.
Take the cookies out of the freezer/fridge and put onto two lined baking trays. I put four cookies per tray
Bake the cookies in the oven for 10-12 minutes.
Once baked, carefully push the kinder bueno into the top of the cookies and leave the cookies to cool on the tray for at least 30 minutes, as they will continue to bake whilst cooling
The kinder bueno chocolate can melt slightly, so these will be soft until the cookies have cooled fully.
ENJOY!
Notes
These will last for 4-5+ days once baked!
The Kinder Bueno on top is optional, but delicious!
You can freeze the raw cookie dough for 3 months, and bake from frozen if you don't want to bake the entire batch! If you are baking from frozen, bake for 12-14 minutes.
You can use chocolate chips/chunks in place of the kinder chocolate.
If you want a lovely texture - you can add in 1 level tbsp of cornflour, and take out 25g of the flour!
If you can't access one of the sugars, use all of the other one - i.e. all granulated, or all light brown sugar. Using other sugars can change the texture.
You can make the cookies 120g each, and bake for 12-14 minutes, or smaller at 60g each and bake for 9 minutes.
If you want to stuff the cookies
Freeze heaped teaspoons of spread.
Wrap the cookie dough around the frozen spread, and chill the cookies like normal.
