Lets get to know how to make these chocolate chip cookie bar 8x8
This recipe is an offspring from my Soft chewy Chocolate chip Cookie. Its an easy simple cookie dough to mix, with some of the basic ingredients that is available off your pantry. And this recipe is meant for an 8x8 pan, and not any other pan. For other bar recipes you may like
Now for the Ingredients
- Flour - just plain all purpose flour- you can also use half bread flour and half all purplose flour, gives a little more chewier cookie bar. But I have used only all purpose flour
- Butter - Melted unsalted butter. We use unsalted melted butter, to give a nice chewy texture.
- Sugar - Granulated white sugar and Brown Sugar. Using granulated white sugar will give good structure and brown sugar will give moistness and chewiness.
- Baking powder and baking soda for the leavening
- Eggs - large eggs here. We use eggs here for structure flavour and the moisture it lends to the cookie bar.
- Chocolate chips - semisweet or dark chocolate chips is just fine.

Mixing the dough for these cookie bars are absolutely quick. but first we need to make truffle filling. or chocolate ganache. Because it needs time to set.
TRUFFLE FILLING, Simple 2 ingredient ganache filling, - heat the cream and add in the chopped chocolate. Let it sit. and then mix to make a truffle filling. you will use this to fill in between the cookie dough layers. This needs to set until it is of spreadable consistency

How can we replace egg in this recipe
Shrilatha says
Yes Roopal,
you can replace - 3 tbsp flax seed powder mixed with 1 tbsp water, whisk set aside for 5 mins, then add this in place of eggs for this recipe. This is general replacement for eggs in a cookie recipe.
Hope this helps.
Happy baking
Lana Kung says
What temperate is baking oven?
Shrilatha says
temperature for baking this recipe is what you are asking for?
Please read the recipe.
You can bake this at 170 deg celsius. Preheat for 15 mins before baking
Makayla Dillard says
These cookies are very good but if your looking for the temperature of it it’s 325 degrees Fahrenheit if your American. I recommend putting them in for at least another 10 mins because mine were not cooked even after 18 mins
Linda says
the oven Temperature is not anywhere in the recipe. Another cookie recipe I read said 375* F but your commenters say 325 but had to bake 10 minutes longer so I am going with 325* F without the ganache filling will see how it does!
Shrilatha says
yes you may go ahead with 375F
