Egg Yolk Chocolate Chip Cookie Bars Ingredients
- Softened butter: I love creaming the butter with the sugar until I get a creamy consistency.
- Brown sugar & granulated sugar: I love the mix of sugars for sweetness and texture.
- Chocolate chips: milk, semi sweet, or dark chocolate
- Egg yolks: gives these cookie bars an almost fudgy, dense texture.
- Vanilla paste. I love going heavy on vanilla in my cookie bars, so instead of 1 teaspoon vanilla, I used 2. You can even use a tablespoon!
- All purpose flour: I love King Arthur flour. Don't try to swap in almond flour or coconut flour here as they won't work.
- Baking Soda. Just the right amount for spread and puff.
- Plenty Of Chocolate Chips. My favorite chocolate chips for these gluten-free cookie bars are semisweet chocolate chips, but feel free to milk chocolate chips for even sweetener cookie bars or dark chocolate chips for more intense chocolate flavor, or .
How to Make these Egg Yolk Chocolate Chip Cookie Bars, step by Step
- Preheat & Prep. Preheat the oven to 350F. Line a 9x13 baking pan with parchment paper.
- Mix butter & sugars. In a large mixing bowl combine the softened butter, brown sugar, and granulated sugar. Mix with a spatula attachment until just combined.
- Add egg yolks, and vanilla and mix to combine. Scrape down the sides of the bowl.
- Mix in the flours most of the way until just a few steaks of flour remain.
- Add the chocolate chips and fold until evenly distributed.
- Press the cookie dough into the prepared pana nd smooth into an even layer
- Bake the cookie bars 22-25 minutes or until the edges are set and the top is golden brown. The center of the cookie bars will not be fully set, but the a toothpick will come out clean.

Expert Tips
- Try not to over bake the bars: Bake until the edges are golden brown and the center is not wet. The bars will continue to cook in the pan when you remove the bars from the oven to cool.
- Cool bars: I know, waiting is the hard part! I recommend cooling on a wire rack for 20 minutes or until you can easily pick it up or cut through without it falling apart. They are best when they are still warm and the chocolate is melty.
- Customize your cookie dough: Add in nuts, white chocolate chips, butterscotch chips, etc.
When to Slice and Serve Cookie Bars
When the cookie bars are done baking, allow them to cool for a half hour. If you used parchment paper, carefully lift from the pan and place on a cooling rack. Feel the if the bottom is slightly warm. If the bars start to bend in the center, the it is too soon to lift them.
Use a large knife to make even slices. For clean cuts, wipe off the knife in between each cut. Enjoy while still slightly warm so you can taste the gooey chocolate.
Egg Yolk Chocolate Chip Cookie Bars FAQ
What is the best chocolate to use? My all time favorite chocolate is Ghirardelli! The second is the Guittard chocolate chips! You can pick dark chocolate or semi sweet!
Can I make them dairy-free? I haven't tested them dairy-free, but you can probably use vegan butter sticks (like Country Crock) and dairy-free chocolate chips (like Enjoy Life!).
Measure carefully! It is very important to measure your flour correctly for these bars. too much will make the bars too dense or dry. Too little and they wont form properly. Try using the scoop and level method to get an accurate measurement as possible.
Try chocolate chinks! For bigger puddles of chocolate and a fudgier taste, you can totally use chopped chocolate instead of chips.
