Heath Bar Cookies

These Heath Bar Cookies are filled with chopped heath bars and milk chocolate chips! I mean, how can you go wrong with pools of melted toffee and chocolate?! You are going to love this cookie recipe!

Heath bars are made of toffee, almond, and milk chocolate. The perfect nutty, sweet, and salty combination! The ratio of light brown sugar and granulated sugar in this recipe gives the cookies the perfect texture! They have crispy edges and a chewy and slightly gooey interior! Make sure to not overbake these cookies! They may seem underdone in the center once removed from the oven, but that is exactly what you want! They will continue to bake and set once removed from the oven leaving you with the perfect cookie!

Ingredients for Heath Bar Cookies

All you need are a handful of simple pantry ingredients to make these Heath Bar Cookies!

Unsalted Butter: Use unsalted butter that has been softened to room temperature.
Light Brown Sugar: Make sure to pack the brown sugar into the measuring cup when measuring. The brown sugar gives these cookies their chewy and gooey center.
Granulated Sugar: Use regular granulated sugar to give the cookies their crispy edges.
Eggs: The recipe calls for 2 large eggs that have been brought to room temperature.
Vanilla Extract: Do not use imitation vanilla for this recipe. Use pure vanilla extract for the best flavor.
All-Purpose Flour: Make sure to measure the all-purpose flour using the spoon-and-level method to ensure that the proper amount of flour is used. Adding too much flour will lead to dry and crumbly cookies.
Baking Soda: Leavening agent used to help the cookies spread.
Cornstarch: The addition of 1 tablespoon of cornstarch makes these cookies extra chewy.
Salt: Balances the sweetness of the cookie.
Heath Bar: Use 1 full cup of chopped heath bar in the cookies. I like to use additional to top each cookie before baking.
Milk Chocolate Chips: Use 1 1/2 cups milk chocolate chips in the cookies. I also like to add additional chocolate chips to the cookies.

Chilling the Cookie Dough

This recipe only requires 30 minutes of chilling time! Allowing the cookie dough to chill for half hour allows the butter to solidify ensuring that the cookies do not spread too much in the oven! Also, chilling the cookie dough deepens the flavor of the cookies! If needed, you can chill the cookie dough overnight or up to 48 hours. This makes this recipe the perfect make ahead dessert!

Making Heath Bar Cookies

Cream together butter, light brown sugar, and granulated sugar for 3 minutes until light and fluffy. Add in eggs, one at a time, beating well after each addition. Beat in vanilla extract.
In a separate bowl, whisk together all-purpose flour, baking soda, cornstarch, and salt. Add to wet ingredients and beat until just combined. Mix in chopped heath bar and milk chocolate chips.
Cover and chill in the refrigerator for at least 30 minutes.
Preheat oven to 350 degrees F. Line baking sheet with parchment paper. Using a large cookie scoop, scoop dough onto baking sheet. Top with chopped heath bar and milk chocolate chips – optional, but is it really though 🙂
Bake for 12 minutes. Cool for 3 minutes on baking sheet before transferring to a wire rack to cool completely.
Store in an airtight container for up to 5 days at room temperature or place in freezer for up to 2 months.
