What Makes a Cookie “Thick”?

Getting thick cookies is about technique, not just ingredients:

Use cold or slightly cool dough
Don’t over-mix after adding flour
Use brown sugar for moisture and chew
Chill the dough so the butter doesn’t melt too fast in the oven
Scoop tall mounds, not flat discs

This recipe is built specifically for that bakery-style rise and chew.

Ingredients

Cookie Dough

2 ¼ cups all-purpose flour
¾ cup unsweetened cocoa powder
1 tsp baking soda
½ tsp baking powder
1 tsp salt
¾ cup unsalted butter, softened
¾ cup brown sugar, packed
½ cup granulated sugar
2 large eggs
2 tsp vanilla extract
1 cup semi-sweet chocolate chunks or chips
¾ cup toffee bits
¾ cup chopped walnuts

Instructions

Mix Dry Ingredients
In a medium bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
Cream Butter & Sugars
In a large bowl, beat butter, brown sugar, and granulated sugar until light and fluffy (about 2–3 minutes).
Add Eggs & Vanilla
Beat in eggs one at a time, then mix in vanilla extract.
Combine Wet & Dry
Slowly add dry ingredients into the wet mixture just until combined. Do not over-mix.
Fold in Mix-Ins
Gently fold in chocolate chunks, toffee bits, and chopped walnuts.
Chill the Dough
Cover and refrigerate for 30–60 minutes for best thickness.
Preheat & Scoop
Preheat oven to 350°F (175°C). Scoop tall mounds of dough (about 3 Tbsp each) onto parchment-lined baking sheets.
Bake
Bake 10–12 minutes until edges are set and centers still look soft.
Cool
Let cookies rest on the pan 10 minutes before transferring to a wire rack.

Pro Tips for Perfect Cookies

Chill = Thickness: Even 30 minutes helps prevent spreading.
Use Chocolate Chunks: They melt into gooey pockets better than chips.
Toast the Walnuts: Lightly toast before chopping for deeper flavor.
Don’t Overbake: They firm up as they cool.
For Extra Height: Press two dough balls together stacked vertically.

Flavor Variations

Salted Caramel: Add flaky sea salt on top before baking.
Espresso Chocolate: Add 1 tsp espresso powder to the dough.
White Chocolate Swap: Replace semi-sweet with white chocolate chunks.
Pecan Version: Swap walnuts for toasted pecans.

Serving Suggestions

Serve warm with milk or coffee
Crumble over vanilla ice cream
Package in parchment-lined boxes for gifting
Make ice-cream sandwich cookies

Storage & Freezing

Room Temp: Store baked cookies in airtight container for 3–4 days
Freeze Dough: Scoop dough balls and freeze up to 3 months
Bake From Frozen: Add 1–2 minutes to bake time

Fun Fact

Toffee is made by caramelizing sugar with butter — that’s why it melts into those rich, buttery pockets inside the cookies. Combined with chocolate and walnuts, it creates a classic flavor trio: sweet, bitter, and nutty.

These Thick Toffee Walnut Chocolate Cookies are rich, bold, and totally bakery-worthy. Once you make them, they’ll become your go-to chocolate cookie recipe forever.
