I found these on one of my favourite baking sites, Bakerella.
So what is a pillow cookie? A brownie inside of a biscuit! I know, maybe don’t read further if you are counting calories, or your knees turn to jelly when you think about divine baking.
All you do is make your favourite brownie recipe and the best biscuit recipe you can get your oven mitts on.
Then, place dollops of cookie mixture on a tray, make a dip and pop the brownie mix into the well. Cover the brownie over with more cookie mixture and flatten it slightly so that it will cook like a biscuit.
Lastly, cook and hide the evidence. Just remember if you eat it all before someone sees it, it doesn’t count!
