These cookies are exactly what I reach for when I want something dramatic and reliable: a big, chewy chocolate cookie with buttery toffee and toasted pecan crunch. They bake up tall, glossy and slightly crackled, with a fudgy center thanks to a little melted chocolate folded into a rich, beaten-sugar base. They feel special without being finicky.

I test recipes so you don’t have to. The method here uses melted bittersweet and semi-sweet chocolate combined with butter, a quick puff of instant pudding mix for extra chew, and a rest in the fridge so the dough behaves in the oven. The result is big cookies that hold their shape and have that toffee-pecan finish that keeps people coming back for one more.

Below you’ll find the ingredient breakdown (with notes), step-by-step instructions exactly as written, and practical tips for swapping, fixing problems, and storing. Read the steps through once, gather your tools, and you’ll have bakery-style giant cookies in about an hour from start to finish.

Ingredient Breakdown

Ingredients

1 1/2 cups bittersweet chocolate chips (10 oz bag) — Provides the deep chocolate base and melts with butter to make a glossy chocolate mixture.
3/4 cups semi-sweet chocolate chips — Adds a milder, sweeter chocolate layer and extra pockets of chocolate in the finished cookie.
1/2 cup unsalted butter — Melts with the chocolate to make the fudgy liquid that enriches the dough; unsalted lets you control seasoning.
1/2 cup all-purpose flour — Structure for the cookie; used sparingly here so the centers stay moist.
1 tsp baking powder — Gives lift so these cookies rise and develop that giant cookie profile.
3.9 oz instant chocolate pudding mix (1 box) — Adds chew and moisture; it’s an important texture component in this recipe.
1/2 tsp salt — Balances sweetness and enhances chocolate flavor.
1 1/2 cups brown sugar — The primary sweetener; brown sugar keeps the cookie chewy and adds caramel notes.
1/4 cup granulated sugar — Helps with some lift and a little crunch on the exterior.
3 large eggs — Provides structure and richness; beaten thoroughly to incorporate air into the dough.
1 tbsp vanilla extract — Flavor lift; pairs with chocolate and toffee.
8 oz Heath toffee bits (found in the baking aisle) — The toffee crunch and caramel-burnt-sugar flavor—key to the cookie’s character.
1 cup pecans, toasted (optional) — Adds nutty crunch and flavor; optional but recommended for texture contrast.

Step-by-Step: Giant Chocolate Toffee Pecan Cookies

In a microwave-safe bowl, combine 1 1/2 cups bittersweet chocolate chips (10 oz bag), 3/4 cup semi-sweet chocolate chips, and 1/2 cup unsalted butter. Microwave on high for 30 seconds, stir, microwave 30 seconds more and stir again. Continue heating in 10-second increments, stirring after each, until the chocolate and butter are melted and smooth. Set the bowl aside to cool for 2–3 minutes.
In a small bowl, whisk together 1/2 cup all-purpose flour, 1 tsp baking powder, the 3.9 oz box instant chocolate pudding mix, and 1/2 tsp salt. Set this dry mixture aside.
In a large mixing bowl, beat 1 1/2 cups brown sugar, 1/4 cup granulated sugar, and 3 large eggs with a hand or stand mixer on medium-high speed for about 5 minutes, until the mixture is thick and pale.
Beat in 1 tbsp vanilla extract, then slowly beat in the cooled chocolate-butter mixture until incorporated and smooth.
Using a spatula, gently fold the dry flour/pudding mixture into the chocolate-sugar-egg mixture just until combined; do not overmix.
Stir in 8 oz Heath toffee bits and 1 cup toasted pecans (optional) until evenly distributed.
Cover the dough and refrigerate for 30 minutes to firm up.
Preheat the oven to 350 degrees F. Line baking sheets with parchment paper and position racks in the center of the oven.
Using a 1/4-cup measure, scoop portions of dough onto the prepared baking sheets, spacing the mounds about 3 inches apart.
Bake for 14 minutes. Remove the sheets from the oven and let the cookies cool on the baking sheets for 5 minutes.
Transfer the cookies to a wire cooling rack to cool completely.

What You’ll Love About This Recipe

These cookies are large without being greasy. The melted chocolate folded into beaten eggs and sugar gives a glossy, fudgy interior while the instant pudding mix keeps them chewy day two. The toffee bits provide small, crunchy caramel explosions throughout—balanced by the toasted pecans for a nutty finish.

They’re forgiving: a short chill firms the dough so the cookies bake up tall rather than flat. The method uses common pantry items and one small convenience item (instant pudding mix) to achieve that bakery-chewy texture at home. They also freeze well, so you can make a batch and defrost a couple at a time.

Vegan & Vegetarian Swaps

Vegetarian notes

The recipe is vegetarian as written (contains eggs and dairy). No changes needed if you avoid meat products.

Vegan swaps

To make these vegan, swap the butter for a plant-based butter of the same volume and choose dairy-free bittersweet and semi-sweet chocolate chips. Replace eggs with an appropriate egg replacer or follow the package directions for flax/chia egg substitutes instead of the three eggs. Be aware that instant pudding mixes and store-bought toffee bits often contain dairy; look for labeled vegan pudding or omit the pudding mix and toffee, or find vegan toffee substitutes if you want to maintain texture and flavor.

Note: these changes will affect texture and may require slight timing adjustments in the oven. Chill the dough until firm before baking to help the cookies rise and hold their shape.

Equipment Breakdown

Microwave-safe bowl — for melting chocolate and butter quickly.
Mixing bowls — one small bowl for dry ingredients and one large for the sugar/egg mixture.
Hand mixer or stand mixer — necessary to beat the sugars and eggs until thick and pale; hand-beating will work but takes longer.
Spatula — for folding ingredients together gently.
Measuring cups and spoons — accurate measuring keeps texture consistent.
1/4-cup scoop or measuring cup — to portion the large cookie mounds consistently.
Baking sheets and parchment paper — ensure even baking and easy cleanup.
Wire cooling rack — for proper cooling and to prevent sogginess.

Common Errors (and Fixes)

Cookies spread too much: Dough was likely too warm when baked. Chill the dough for the full 30 minutes or longer until firm. Also make sure your butter/chocolate mixture has cooled for the 2–3 minutes specified before beating into the eggs.
Cookies are flat and greasy: Over-melting or overheating the chocolate/butter can thin the fat. Heat just to melting and stir frequently. Chill the dough if the kitchen is warm.
Centers are underbaked or too soft: The cookies should be removed after 14 minutes and rested on the sheet for 5 minutes; they continue to set. If your oven runs cool, add 1–2 minutes, watching carefully.
Cookies are dry or cakey: Overmixing the dry ingredients into the chocolate mixture will activate the flour and make a dryer texture. Fold just until combined.
Uneven chocolate distribution: If chocolate solidifies quickly while mixing, ensure the melted chocolate/butter is slightly cooled but still pourable before blending into the egg mixture to incorporate smoothly.

Smart Substitutions

Pecans: Substitute walnuts or chopped almonds if preferred; toasting enhances flavor—toast briefly in a dry skillet until fragrant.
Heath toffee bits: If you can’t find Heath, use any toffee bits or chopped hard toffee candy. If none are available, add extra chocolate chips for pockets of sweetness.
Instant pudding mix: This ingredient contributes chew. If you omit it, expect a slightly different texture—cookies will still be tasty but a touch less chewy.
Butter: You can use salted butter; reduce or omit added salt if using salted.
Chocolate chips: Swap proportions between bittersweet and semi-sweet to taste, but keep the total chocolate amount similar for melting behavior.

Chef’s Notes

Beat the sugar and eggs for the full five minutes. That aeration gives the cookies lift and a lighter bite despite their size. When melting chocolate and butter, remove the bowl from heat while tiny unmelted pieces remain and stir; residual heat will finish melting without scorching.

Spacing matters: these are big cookies. Give each mound about 3 inches to allow for gentle spreading while keeping them tall. If you want an even shinier top, press a few extra chocolate chips into each mound immediately after scooping to create a glossy finish as they bake.

Refrigerate, Freeze, Reheat

Refrigerate: Store cooled cookies in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate up to 1 week—bring to room temperature before serving for best texture.

Freeze: Freeze baked cookies in a single layer on a sheet until firm, then transfer to a freezer-safe bag or container. They keep for up to 3 months. You can also freeze scooped dough mounds on a parchment-lined tray until firm, then store frozen. Bake from frozen, adding a few extra minutes to the bake time.

Reheat: Warm a cookie in the microwave for 10–15 seconds to revive a soft center, or 5–7 minutes in a 300°F oven for a warmed-through texture. Watch closely to avoid over-drying.

Time to Try It

Gather your bowl, your favorite chocolate chips, and that bag of Heath toffee bits. Follow the steps in order, don’t rush the beating or the chill, and you’ll end up with bakery-style Giant Chocolate Toffee Pecan Cookies that impress guests—and that you’ll happily keep in the freezer for emergencies. Let me know how your first batch turns out and whether you kept the pecans or went nut-free; I love swap stories.
