If there is one cookie you should eat for the rest of your life, it's these brownie marbled chocolate chip cookies. These cookies are literally as if a brownie and a cookie had a baby. They are half brownie, half chocolate chip cookie. With crisp edges and a gooey center with puddles of melted chocolate, they are to die for.

Brownie marbled chocolate chip cookies
Okay so what are brownie marbled chocolate chip cookies. Think a brookie, but in cookie form. We take a brownie based cookie dough and roll it together with a chocolate chip cookie dough and voila! A brownie marbled chocolate chip cookie.
These cookies have crisp edges but a gooey center, and they are loaded up with chocolate. There is melted chocolate INSIDE the brownie cookie dough batter, chocolate chunks throughout the dough AND chocolate puddles on top. It's a chocolate lover's dream.

Ingredients
If you need to run to the grocery store for some ingredients, here is your shopping list:
- Unsalted butter: unsalted butter is my preference in baked goods because it allows you to control exactly how much salt goes into your recipe.
- A combination of brown sugar and granulated sugar is the best for these cookies.
- Egg/egg yolk: we use one egg and one egg yolk to bind the ingredients together and make a super thick, chewy cookie.
- We add vanilla extract and salt for flavor enhancement.
- All purpose flour: all purpose flour is the flour of choice for these cookies - it gives them the most perfect texture.
- Unsweetened cocoa powder: unsweetened cocoa powder (regular, not dutch processed) is a must for the brownie based cookie dough to make it super chocolatey and delicious.
- Baking soda aids the rise of these cookies and gives them that crackly top we all know and love.
- Chocolate chips/chunks: we use A LOT of chocolate in this recipe so make sure to splurge on good quality chocolate. There is melted chocolate in the brownie dough and chocolate chips/chunks mixed in both doughs as well.

How to make the cookies
- Whisk together the unsalted butter, brown sugar and granulated sugar. Add the egg, egg yolk and vanilla extract and whisk until combined.
- Divide the wet ingredients in half into two separate bowls.
- Make the brownie dough by folding in all purpose flour, cocoa powder, baking soda and salt into one half of the wet ingredients. Add the melted chocolate and fold together until combined. Add the chocolate chunks.
- Make the chocolate chip cookie dough by folding in all purpose flour, baking soda and salt into the other half of the wet ingredients. Add the chocolate chunks.
- Let the dough chill for one hour, then preheat your oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper.
- Take one heaping tablespoon of brownie dough and one heaping tablespoon of chocolate chip cookie dough and roll them together.
- Bake for 12-14 minutes until the edges are set and lightly golden. Enjoy!
