Brownie Cookie Squares

Everyone likes brownies, right?   And everyone likes cookies, too.   At the very least, those good people who are reading this (And make no mistake, you are awesome people….everyone else?   Not so much)

So, what better way to double your fun than to combine a cookie and a brownie into one delicious treat?   I can’t think of any, so here are these brownie/cookie Frankenstein creations.    If Frankenstein were edible of course (He’s made of rotted corpses, so eww.    Plus, cannibalism.)    But we are talking some serious chocolatey goodness here.


Cookie layer

·        ½ cup butter, softened to room temperature

·        ½ cup dark brown sugar

·        ¼ cup sugar

·        1 t vanilla

·        1 egg

·        1 ¼ cups flour

·        ½ t salt

·        ½ t baking soda

·        1 cup semi-sweet chocolate chips

Brownie layer

·        ½ cup butter, softened to room temperature

·        1 cup white sugar

·        1 ½ t vanilla

·        2 eggs

·        1/3 cup cocoa powder (dark if you have it, regular is fine)

·        ½ cup flour

·        ¼ t baking powder

·        ¼ t salt

·        Walnuts (if you want – I say no but who am I to judge)


Grease up a 9×13 baking dish (or as close as you’ve got), or line it with aluminum foil.  First we’re gonna make the cookie layer.

Beat the butter, brown sugar, sugar and vanilla until its smooth.   Then add the egg and beat some more until it’s all combined together – a couple minutes should do it.  Set this aside.

In another (small) bowl, mix together the flour, salt and baking soda and then pour that flour mixture into the butter mixture and mix it with a wooden spoon until it’s completely combined.   Then add in the chocolate chips and mix completely.


Spread the dough into the baking dish so that it covers the bottom completely and press down with your fingers.  Now…on to the brownie layer.


It gets messy…

Beat the butter, sugar and vanilla in a bowl.   Then, add the eggs and beat that until it’s completely combined, again probably a couple minutes.  Put in the cocoa powder – mix a little with a wooden spoon so is under a layer of the butter mixture and then beat (you just do this so that the cocoa powder doesn’t go flying everywhere when you use the hand mixer).

Finally pour in the flour, baking powder and salt.   Again, mix it a bit with the wooden spoon so that the flour is covered by the wet mixture and then beat with your hand mixer until completely combined.   You’re done with this, but if you want to add walnuts (maybe a cup), do it now and mix in with a wooden spoon.

I did not add walnuts…

Pour the brownie batter over the cookie dough and make sure the cookie dough is completely covered.

Bake at 350 for about 20-25 minutes, until the brownie is at the consistency you like.   If you want it fully cooked through, go longer.   If you want it a little gooey in the center then go a little shorter.


Cool in the pan on a wire rack and cut into squares when it’s fully cooled.
