Thick Chocolate Chip Cookies
These thick chocolate chip cookies are soft and chewy in the center with slightly crisp edges, full of butter and brown-sugar flavor and studded with melting chocolate. They’re worth making when you want a bakery-style cookie that holds its shape and feels substantial — perfect for dunking or sandwiching with ice cream.
I make a batch whenever I want something comforting but simple; the technique is straightforward and the dough benefits from a short chill so the cookies stay tall and tender.
Why This Thick Chocolate Chip Cookies Works
1. Higher flour ratio and a bit of cornstarch give structure so the cookies stay thick instead of spreading.
2. Brown sugar adds moisture and chew, balancing the crisp edges with a tender center.
3. Chilling the dough firms the butter and concentrates flavor, which reduces spread and deepens taste.
4. Chunky or chopped chocolate creates pockets of melty chocolate and a pleasing texture contrast.
Ingredients
These are the key players — each one affects texture or flavor, so I mention simple choices and swaps.
MORE OF OUR FAVORITE…
– All-purpose flour: The main structure; spoon and level or weigh for best results.
– Cornstarch: A small amount helps cookies stay soft and thick.
– Brown sugar: Adds moisture and chew — light or dark both work, dark gives a deeper molasses note.
– Unsalted butter: Use good-quality butter; chill slightly before scooping to reduce spread or use room-temp for easier creaming depending on the method.
– Eggs (or extra yolk): Egg brings stability; an extra yolk adds richness and chew.
– Baking soda and salt: Leavening and seasoning — salt enhances the chocolate flavor, a little flaky salt on top is a nice finishing touch.
– Chocolate chips or chopped chocolate: Chopped chocolate melts into pockets and gives varied texture; use a mix of semisweet and milk if you like.
Substitutions and Variations
– Swap some all-purpose flour for bread flour (up to half) for a chewier, taller cookie.
– Use melted butter instead of creamed butter for a denser, fudgier interior but expect slightly more spread.
– Replace part or all of the brown sugar with coconut sugar for a nuttier flavor and similar moisture.
– Use a mix of dark chocolate and milk chocolate to vary sweetness and mouthfeel.
– Stir in chopped toasted pecans or walnuts for crunch — they won’t change bake time much.
– For gluten-free, use a 1:1 measure-for-measure GF flour blend and add a touch more cornstarch if needed for structure.
How to Make Thick Chocolate Chip Cookies
This is a concise overview — the full recipe card has exact amounts and oven temperature.
1. Whisk together dry ingredients (flour, cornstarch, baking soda, salt) in a bowl and set aside.
2. Cream butter and sugars until light and slightly fluffy, then beat in eggs (or egg + extra yolk) and vanilla.
3. Fold dry ingredients into the wet just until combined; avoid overmixing.
4. Stir in the chocolate chunks or chips evenly.
5. Chill the dough in the fridge for at least 30 minutes (up to 24 hours) to firm and develop flavor.
6. Scoop large rounds of chilled dough onto a lined baking sheet, leaving space between cookies.
7. Bake until edges are set and centers look just slightly underdone; cool on the pan a few minutes before transferring to a rack.
Tips for the Best Results
1. Chill the dough — even 30–60 minutes helps the cookies stay thick and develop better flavor.
2. Use a large cookie scoop for consistent size so bake time is predictable.
3. Bake until edges are golden and centers are soft — they’ll firm as they cool; skipping this keeps them tender.
4. Line pans with parchment or a silicone mat to prevent excess spreading and promote even browning.
5. If cookies brown too quickly, lower the oven temp by 10–15°F (5–10°C) or place the sheet on a lower rack.
Common Mistakes
– Using too-warm dough: dough that’s room-temperature will spread more; chill briefly to fix it.
– Overmeasuring flour by packing the cup: spoon flour into the cup or weigh it to prevent dry, dense cookies.
– Overbaking until completely firm: remove when centers are still soft for a chewy interior.
– Crowding the baking sheet: cookies need room to rise and brown evenly — bake in batches if needed.
– Skipping cornstarch or extra yolk when the recipe calls for them: these small additions help keep cookies thick and tender.
Storage
Storing: Keep baked cookies in an airtight container at room temperature for 3–4 days; separate layers with parchment to avoid sticking.
Freezing: You can freeze either the baked cookies or the scooped, chilled dough. Freeze dough balls on a tray then transfer to a freezer bag — bake from frozen, adding a couple minutes to the time. Baked cookies freeze well for up to 2 months; thaw at room temperature.
Reheating or serving later: Warm a cookie in the microwave for 8–10 seconds or in a 300°F (150°C) oven for 5–7 minutes to revive that just-baked texture.
How to Serve Thick Chocolate Chip Cookies
– Serve warm with a glass of cold milk.
– Sandwich two cookies with a scoop of vanilla ice cream for an easy dessert.
– Break into chunks and sprinkle over vanilla pudding or yogurt for texture.
– Pack in a lunchbox or gift tin — they travel well when cooled completely.
More Helpful Notes
– Use good-quality chocolate for the best flavor; big chunks create better melty pockets than tiny chips.
– A few flakes of sea salt on top before baking brighten the chocolate and balance sweetness.
– If you want perfectly round cookies, gently press the chilled dough balls to flatten slightly before baking.
– Let cookies rest on the hot pan for 4–6 minutes after removing from the oven to finish setting without drying out.

Thick Chocolate Chip Cookies
Ingredients
Cookie Dough
- 1 cup (226g) unsalted butter, cool room temperature
- 3/4 cup (160g) packed light brown sugar
- 2/3 cup (130g) granulated sugar
- 1 large egg
- 1 large egg yolk
- 2 teaspoons (10ml) pure vanilla extract
- 3 1/3 cups (400g) all-purpose flour
- 1 tablespoon (8g) cornstarch
- 1 tablespoon (8g) milk powder
- 1 teaspoon (4g) baking soda
- 3/4 teaspoon (4g) fine sea salt
- 1/2 teaspoon espresso powder
- 1 bag (12oz/340g) semi-sweet chocolate chips
Instructions
Preparation Steps
- Whisk together the flour, cornstarch, milk powder, baking soda, salt, and espresso powder in a large bowl; set aside.
- In a stand mixer fitted with the paddle (or using a hand mixer), beat the butter, brown sugar, and granulated sugar on medium-high until very fluffy and a few shades lighter, 3 to 4 minutes. Scrape the bowl.
- Mix in the egg, egg yolk, and vanilla on medium speed just until smooth and glossy, about 30 to 45 seconds. Do not overmix after the eggs are added.
- Add the dry ingredients in two additions on low speed until a thick dough forms with a few dry streaks remaining. Finish by folding with a spatula until no flour remains. Fold in the chocolate chips.
- Let the dough rest 10 minutes at room temperature, then refrigerate for 15 to 20 minutes to slightly firm up. During this chill, position a rack in the center of the oven, preheat to 365°F (185°C), and line two baking sheets with parchment paper.
- Portion the dough into 12 mounds of about 4 ounces (113g) each. Stack each portion into a tall, slightly rough cylinder to encourage height and a thick center. Arrange 6 per sheet, leaving space to spread.
- Bake one tester cookie first to gauge your oven: 14 to 16 minutes, or until the edges are set and deep golden and the tops look puffed and matte (the centers should still feel soft). Adjust time as needed, then bake the remaining cookies.
- If you want perfectly round cookies, immediately scoot a round cutter around each hot cookie to tidy the edges. Cool on the sheet for 10 minutes, then transfer to a rack to finish cooling.
- Bake the second tray on a fully cooled sheet to prevent excess spread.
