Easy and Delicious Chocolate Box Cookie Bars - your favourite chocolates, in Cookie Traybake form!
Preheat your oven to 190C/170C Fan and line a 9x9inch Square Tin with parchment paper, and leave to the side for now.
Whisk/Mix the Plain Flour, Bicarbonate, Salt and Cornflour together so its evenly distributed – leave to the side.
In a larger bowl, melt the butter. Add in the two sugars, and whisk for about 2 minutes so the sugar starts to dissolve and the mixture is smooth.
Add in the Egg and the Vanilla, and whisk again briefly till smooth. (I used an electric whisk)
Add in the Dry Ingredients and the Chocolate Chips and mix with a spatula till a thick cookie dough is formed.
Finally, add in the Chocolates! I don't chop mine up. Fold through the mixture as best you can!
Press the mixture into the bottom of the tin - Bake the traybake in the oven for 18-22 minutes, until the top of the cookie bake looks ‘dry’!
Leave the cookie bake to cool for about 10 minutes, then leave to cool fully on a wire rack. Cut the bake into 4×4 for decent sizes, or 5×5 for smaller ones! Enjoy!
