Tips For Making Heath Bar Cookies

• Use room temperature eggs – Room temperature eggs will bind easier and give your cookies a more cohesive dough and better texture.
• Make sure the baking soda and powder are active – There’s nothing worse than baking a batch of cookies only to have them flatten out during baking. To ensure these ingredients are still effective, try this simple test: Mix a teaspoon of baking powder with a little hot water. If it bubbles, it’s still active. Then, combine baking soda with vinegar; if it fizzes, it’s also ready to go.
• If you don’t have Heath Bar chips – No candy bars, no problem, substitute with chocolate chips. This recipe use the same dough as my chocolate chip cookie recipe. If you don’t have any Heath bars handy, substitute with chocolate chips for the perfect chocolate chip cookie recipe.
• Keep your brown sugar moist – Invest in a brown sugar disc or place a piece of apple or bread in your brown sugar container to help the brown sugar retain moisture.
• Consistent-sized cookie dough – Make sure your Heath Bar cookie dough balls are the same size so they bake at the same pace. Use a measuring spoon or cookie scoop.
• Don’t over cook them – When you take the cookies out of the oven, they may appear slightly undercooked. The cookies will continue to cook for a few minutes after being removed from the oven. If overcooked these cookies will be very crispy.

Ingredients

You don’t need anything fancy for these Heath Bar Toffee Cookies—just a handful of pantry staples and some crushed-up Heath bars (or any toffee candy you love). Here’s what you’ll need to make them:

• All purpose flour: Use all purpose flour for these cookies. For gluten-free cookies, you can most likely use a 1-1 gluten free flour.
• Baking powder/baking soda: I used both baking powder and baking soda to get a soft, light texture.
• Butter: Unsalted butter helps make these cookies rich and creamy. Make sure it’s softened to room temperature so it creams properly with the sugars. If you only have salted you can use it and adjust the amount of added salt.
• Brown sugar: Brown sugar adds a nice caramel-like sweetness to the cookies; light brown sugar or dark brown sugar will both work. I much prefer brown sugar to granulated sugar for making chocolate chip cookies.
• Vanilla: Don’t skip it! Vanilla adds warmth and brings out all the toffee and chocolate flavors. Use real vanilla extract for the best taste though artificial vanilla will work.
• Eggs: You’ll need one whole egg, preferably room temperature. This helps bind everything together to create a tender and chewy cookie.
• Toffee Chips: You want chunks—not dust—so you get that signature toffee crunch and melty chocolate in every bite.

Recipe Variations

There are so many fun ways to switch up these Heath Bar Toffee Cookies depending on what you have on hand—or the vibe you’re going for. Here are a few easy variations to try:

• Add chocolate chips – Stir in ½ cup of semi-sweet or milk chocolate chips for extra melty goodness. Want to go bolder? Try dark chocolate chunks to balance the sweetness of the toffee.
• Holiday twist – Add red and green M&M’s or festive sprinkles to turn these into the perfect Christmas cookie. You can even drizzle with melted white chocolate and top with crushed peppermint for a wintery version.
• Go nutty – Fold in ½ cup of chopped pecans or almonds for added crunch and a buttery, nutty depth.
• Salted toffee vibe – Sprinkle a little flaky sea salt on top right after baking. It balances the sweetness and makes these feel extra fancy.
• Other candy bars – No Heath bars? You can swap in chopped Skor bars, Butterfinger, or even Snickers for a different flavor combo.

How to Store or Freeze

These Heath Bar Toffee Cookies store and freeze beautifully, which makes them perfect for make-ahead baking—especially for those holiday cookie trays!

To store: Once cooled, keep the cookies in an airtight container at room temperature for up to 4–5 days. I like to layer them with parchment paper if I’m stacking them, especially if any chocolate bits are exposed—they can get a little sticky.

To freeze the dough: Scoop the cookie dough into balls and freeze them on a baking sheet until firm. Then transfer to a freezer-safe bag or container. Bake straight from frozen by adding 1–2 extra minutes to the bake time—super convenient for last-minute sweet cravings.

To freeze baked cookies: Let the cookies cool completely, then freeze in a single layer or with parchment between layers. They’ll stay fresh in the freezer for up to 2 months. When you’re ready to eat, just let them thaw at room temp or pop them in the microwave for 10–15 seconds for a warm, gooey treat.
