Chewy Chocolate Chip Cookies Made with Egg Yolks

Soft, chewy, and richly flavored egg yolk cookies loaded with chocolate chips — an ideal way to use leftover yolks from buttercream or meringue.

I bake these egg yolk chocolate chip cookies whenever I have extra yolks. As a French baker who loves American-style cookies, I perfected this method to keep the cookies thick, tender, and intensely flavorful.

Using only egg yolks (no whole eggs) gives these cookies a richer mouthfeel and a more tender crumb while preserving the classic contrast of soft centers and slightly crisp edges.

Why you’ll love this recipe

• Uses egg yolks only: A great solution when you have leftover yolks and want richer cookies.
• Rich, chewy texture: Egg yolks yield soft centers with golden, crisp edges.
• Simple and flexible: Easy to adapt with different chocolates or add-ins.

Ingredients you need

Gather these everyday ingredients to make egg yolk chocolate chip cookies:

• 120 g unsalted butter (softened; or melted then cooled)
• 50 g granulated sugar
• 100 g light brown sugar (packed)
• 3 egg yolks (room temperature — about 50–60 g total)
• 1 tsp vanilla extract
• 210 g all-purpose flour (about 1 2/3 cups)
• ¾ tsp baking soda
• ¾ tsp salt
• 150 g chocolate chips (or chopped chocolate)

Tips for best results

• Room temperature: Bring butter and yolks to room temperature so they blend smoothly.
• Don’t overmix: Cream butter and sugars well, then stop mixing once the flour is incorporated to avoid tough cookies.
• Uniform portions: Use a scoop for even-sized dough balls so cookies bake evenly.
• Chill the dough: Refrigerate the dough for 30–60 minutes (or 20 minutes in the freezer) to control spread and develop flavor.
• Slightly underbake: Remove cookies when edges are set but centers are still soft; they firm up as they cool.

How to make egg yolk chocolate chip cookies

These cookies use the classic chocolate chip method but rely on yolks for extra richness. Follow these steps:

1. Cream: In a large bowl, beat the softened butter with granulated and brown sugar for 2–3 minutes until smooth and creamy.

2. Add yolks and vanilla: Mix in the egg yolks and vanilla until fully combined and glossy.

3. Fold in dry ingredients: Gently stir in the flour, baking soda, salt, and chocolate chips with a spatula until just combined; the dough should be slightly sticky.

4. Portion and chill: Scoop dough into even balls and place them on a parchment-lined baking sheet. Chill the dough balls for 1 hour in the fridge (or 20 minutes in the freezer).

5. Bake: Preheat your oven to 350°F (180°C). Bake cookies for about 12 minutes, until the edges are lightly golden and the centers still look soft.

6. Cool: Let cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to finish cooling. Sprinkle with a few sea salt flakes if you like.

Storage

• Store baked cookies in an airtight container at room temperature for 5–7 days.
• Freeze baked cookies up to 2 months; thaw at room temperature before serving.

Recipe variations

• Chocolate chunk: Use chopped dark chocolate for large pockets of melty chocolate.
• Milk chocolate: Swap dark chips for milk chocolate for a sweeter cookie.
• White chocolate: Try white chocolate chips for a richer, sweeter bite.
• Nutty: Fold in chopped hazelnuts or walnuts for crunch and flavor.

If you have leftover egg whites, you can use them in meringues or other recipes. For a different cookie style, try a double chocolate version or shape the dough into one large cookie for a gooey center.

Recipe questions

Can you make cookies with egg yolks only?

Yes. Replacing whole eggs with yolks produces a richer, more tender cookie with a slightly denser crumb.

Can I use whole eggs instead of egg yolks?

This recipe is formulated for yolks only. Using whole eggs will change the texture and spread; follow a whole-egg cookie recipe if you prefer that result.

Why chill the cookie dough?

Chilling firms the dough, prevents excessive spreading, and improves flavor and chewiness.

Can I freeze the cookie dough?

Yes. Freeze dough balls up to 2 months. Bake from frozen, adding 1–2 minutes to the baking time.

Do egg yolk cookies taste different?

Yes. Egg yolk cookies taste richer and more tender, with a deeper flavor compared to versions made with whole eggs.
