Ingredient Overview

This chocolate chip cookie bark is made with simple pantry ingredients, but each one plays a role in getting the right texture and that signature snap.

Unsalted butter - Melted butter keeps the cookie layer thin and dense instead of cakey.
Granulated sugar - Helps the cookie bake up crisp and gives the bark structure.
Light brown sugar - Adds just enough moisture and chew without making the cookie soft.
Egg - Binds everything together and gives the cookie layer stability.
Vanilla extract - Adds warmth and rounds out the chocolate flavor.
All-purpose flour - The base of the cookie layer. Measuring accurately keeps the bark thin.
Baking soda - Helps the cookie spread evenly across the pan.
Salt - Balances the sweetness and brings out the chocolate.
Mini chocolate chips - I love using semisweet chocolate chips! You can use whatver you have!
Dark chocolate - Creates the snappy top layer that gives the bark its crack. My fav brand to reach for is ghirardelli or the trader joes brand!
Coconut oil - Optional, but helps the chocolate melt smoothly and set with a clean snap.
Red and pink M&M's - Add crunch, color, and a festive Valentine's finish.

This recipe comes together in one bowl and one pan, with no shaping or chilling required before baking.

Prep the pan: Preheat the oven to 350°F (175°C) and line a rimmed large baking sheet with parchment paper, leaving an overhang for easy removal.
Mix the cookie dough: Whisk together the melted butter, granulated sugar, and brown sugar until smooth and glossy. Add the egg and whisk until fully combined, then stir in the vanilla extract.
Add the dry ingredients: Fold in the flour, baking soda, and salt just until combined, then gently fold in the mini chocolate chips.
Bake the cookie layer: Press the dough evenly into the prepared pan, aiming for about ¼-inch thickness. Bake for 16-18 minutes, until the entire surface is evenly golden and set. Let cool completely in the pan.
Add the chocolate topping: Melt the dark chocolate in 20-second intervals, stirring between each, until smooth. Stir in the coconut oil if using, then with an offset spatula, spread a thin smooth layer over the cooled cookie slab. Sprinkle with M&M's and finish with flaky sea salt.
Chill and break: Place in the refrigerator for 15-20 minutes, or until the chocolate is fully set. Lift out and break into irregular bark pieces.

What Is Chocolate Bark?

Chocolate bark is a simple dessert made by spreading melted chocolate into a thin layer and topping it with mix-ins like cookies, candy, or nuts before breaking it into irregular pieces once set. It gets its name from the way it's cracked into shards, similar to tree bark. In this recipe, the bark combines a thin chocolate chip cookie base with a snappy chocolate topping, giving you the best of both worlds: cookie flavor with that classic bark-style snap.

Common Mistakes to Avoid

Spreading the dough too thick: A thicker cookie layer will stay soft and bend instead of breaking cleanly. Keep it around ¼-inch for the best texture.
Underbaking the cookie layer: Pale centers mean a soft, bendy base. Bake until the entire surface is evenly golden.
Using chocolate chips for the topping: Chocolate chips are designed to hold their shape and won't set with the same snap as chopped chocolate.
Spreading the chocolate too thick: A thick chocolate layer will flex before it breaks. A thin, even layer snaps better and looks cleaner.
Breaking the bark too soon: If the chocolate isn't fully set, the bark will bend instead of crack. Chill until firm before breaking.
Cutting instead of breaking: Bark is meant to be snapped by hand. Cutting creates blunt edges and can soften the texture.

Frequently Asked Questions

Does chocolate chip cookie bark stay crispy? Yes. As long as the cookie layer is baked through and the bark is stored in an airtight container, it will stay crisp. The chocolate topping also helps lock in texture.
Can I use a different type of chocolate for the topping? Absolutely. Dark, milk, or white chocolate all work, but chopped chocolate bars will give you the best snap.
Why didn't my bark snap when I broke it? This usually means the chocolate layer was too thick or not fully set. Chilling the bark longer and breaking it while cold will give you a cleaner crack.

Store chocolate chip cookie bark in an airtight container at room temperature for up to 3 days. Keep the pieces in a single layer or separate layers with parchment paper to prevent sticking. If your kitchen runs warm, you can store the bark in the refrigerator for up to 5 days, but let it sit at room temperature for a few minutes before serving so the texture isn't too hard.
