These are not ordinary chocolate chip cookies. These egg yolk chocolate chip cookies are enriched with extra yolks resulting in an indulgent treat with a soft texture and delicious depth of flavor.  Using only the egg yolk from the egg, not whole eggs makes a deliciously rich cookie.

This is a perfect recipe for those looking for a treat for those leftover egg yolks after making something that uses only egg whites (like this no-bake strawberry meringue pie.)

Key Ingredients

The recipe amounts for this egg yolk cookie recipe can be found in the printable recipe card at the bottom of this post. Here is a rundown of what you will need.

  • All-purpose flour: The backbone of any good cookie, all-purpose flour provides structure.
  • Cornstarch: ​Makes the cookies extra soft.
  • Egg yolks: These are the stars of the show. Extra egg yolks contribute to a golden brown color, rich flavor, and the cookie’s soft texture. A great way to utilize those leftover yolks!
  • White sugar and soft brown sugar: These two types of sugars are balanced to give the cookies a perfect sweetness, with a hint of molasses flavor from the brown sugar. The brown sugar also makes a more moist cookie. You could also use dark brown sugar.
  • Butter: You can use salted or unsalted butter at room temperature to give the cookies a delicious buttery taste.
  • Vanilla extract: This is added to bring the flavor.
  • Baking soda and baking powder: This helps the cookies rise.
  • Salt: A pinch of salt helps to balance and enhance the sweet flavors. I love to add flaky salt on top of the cookies after baking too. 
  • Chocolate Chips: Choose from dark chocolate chunks or traditional chocolate chips. Both work well in this recipe, it all depends on your preference. I’ve used both!

Method

Preheat the oven and line a large baking sheet with parchment paper.

In the bowl of a stand mixer, or a large mixing bowl if using a hand mixer, cream together the room-temperature butter and sugars until light and fluffy.

Use an ice cream scoop or tablespoons to create individual portions of cookie dough, about 1 1/2 tablespoons per ball. You can chill the cookie dough balls for a couple of hours or up to 36 hours for extra thick cookies or bake them immediately.

Take a cookie ball and dip it into some chopped chocolate. Place the balls of cookie dough on your lined baking sheet, around spaced around 2 inches apart.

Bake the cookies in the preheated oven for 10-12 minutes until puffed and light golden brown but still soft in the middle. A soft-baked chocolate chip cookie will stay chewy. Let them cool on the baking sheet for a few minutes before transferring them to a wire rack to finish cooling.

Variations

There’s room for creativity with these cookies. Add some finely chopped nuts like walnuts or pecans for a little crunch. Or, if you’re a fan of dried fruits, stir through some dried cherries or cranberries.

You could swap the chocolate chips too, for white chocolate or milk chocolate chips.

Storing

To store these cookies, let them cool completely, then put them in an airtight container. They will stay fresh for at least a week at room temperature. If you want to keep them longer, you can freeze the baked cookies or the dough. Both will keep for up to 3 months in a freezer-safe bag or airtight container.
