    King Size Brookie: Two Desserts in One

    Published: Jul 7, 2016 Β· Modified: Aug 6, 2025 by Audrey Β· This post may contain affiliate links.

    Jump to Recipe Print Recipe
    King Size Brookie: half brownie, half chocolate chip cookie. The best of two desserts baked into one giant cookie.

    Imagine biting into a warm, gooey brownie, only to discover a flaky layer of chocolate chip cookie hiding underneath. This indulgent dessert may sound too good to be true, but the Brookie is real. And this recipe makes it even simpler by baking one giant brookie instead of many batches of littler ones.

    This heavenly treat combines the best of both worlds – brownies and cookies – into one delicious and decadent bake.

    Get ready to satisfy your sweet tooth with this delicious fusion dessert.

    Most brookies are individual cookies made in cupcake tins or mini pie pans. But, sometimes you just don't want to heat the kitchen and bake multiple batches of cookies. So, I made it into one giant cookie in my cast iron skillet and cut it into wedges. Smart move on my part.

    How to make King Sized Brookies

    King Size Brookie - half brownie, half chocolate chip cookie, baked in a cast iron skillet. Doubly delicious chocolate dessert.
    Before baking the brownie / after baking 10 minutes / the addition of the cookie dough.

    The only trick to this is to precook the brownies for about 10 minutes before adding the cookie dough to the top. And you might want to check that your camera lens is clean before taking photos... #bloggerproblems πŸ™

    When you add the cookie dough, try to leave some spaces for the brownie to bake through.

    Do you need a Cast Iron Skillet?

    YES! It is perfect for cooking everything from frittatas to pizza to desserts like this. I have a 9" skillet and a sautΓ© pan that pretty much live on my stove because I use them daily.

    Okay, technically you do not need one for this recipe. You can use an 8 or 9" cake pan instead.

    The skillet will give you a crispier edge though.
