Fudgy Brownie Cookies
Bake fudgy cookies with rich brownie flavor and chewy texture.
Ingredients
- 4 oz (113g) unsweetened chocolate, finely chopped
- 1/2 cup (113g) unsalted butter, cut into 1-inch (2.5 cm) cubes
- 1 1/2 cups (300g) granulated sugar
- 1/2 cup (100g) packed light brown sugar
- 2 large eggs, at room temperature
- 1 large egg yolk, at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup (120g) all-purpose flour, spooned and leveled
- 1/2 cup (45g) unsweetened natural cocoa powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup (170g) semi-sweet chocolate chips (or dark chocolate chips)
Instructions
- Preheat oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats.
- Combine finely chopped unsweetened chocolate and cubed unsalted butter in a large, microwave-safe bowl or heatproof bowl over simmering water. Heat 1-2 minutes in microwave on high, stirring every 30 seconds, or stir continuously over simmering water, until chocolate and butter are completely melted and smooth. Remove bowl from heat; cool 5-7 minutes.
- In a separate large mixing bowl, whisk granulated sugar and light brown sugar. Add 2 large eggs, 1 large egg yolk, and pure vanilla extract. Whisk 2-3 minutes until mixture is light in color and ribbons visibly when whisk is lifted.
- Pour cooled chocolate-butter mixture into egg and sugar mixture. Whisk 1 minute until combined.
- In a medium bowl, whisk all-purpose flour, unsweetened natural cocoa powder, baking powder, and salt for 30 seconds.
- Add dry ingredient mixture to wet chocolate mixture. Fold with a rubber spatula or wooden spoon for 1-2 minutes, until no streaks of flour remain. If using, fold in semi-sweet chocolate chips.
- Cover bowl with plastic wrap. Refrigerate dough for 30 minutes to 2 hours.
- Remove dough from refrigerator. Scoop rounded 1.5-inch (3-4 cm) dough balls using a cookie scoop or two spoons. Place dough balls onto prepared baking sheets, spacing 2 inches (5 cm) apart.
- Bake one sheet at a time in preheated oven for 10-12 minutes. Cookies are done when edges appear set and slightly crinkled, with soft, glossy centers.
- Remove baking sheets from oven. Cool cookies on baking sheets 5-7 minutes. Transfer to a wire rack to cool completely. Serve warm or at room temperature.
Notes
- Use room temperature eggs and egg yolk. Remove from refrigerator 30-60 minutes before baking.
- Mix dough until no dry flour streaks are visible. Overmixing creates tough cookies.
- Chill dough for specified time. Chilling prevents spreading and ensures thick, fudgy cookies.
- Store cookies in an airtight container at room temperature for 3-4 days. For longer storage, freeze baked cookies in a freezer-safe bag for up to 2 months. Thaw at room temperature before serving.
- Sprinkle flaky sea salt (Maldon) over cookies immediately after baking for flavor contrast.
Pro Tips for Perfectly Fudgy Brownie Cookies
Ingredient Tips
- Premium Unsweetened Cocoa Powder:Use sifted Dutch-processed cocoa for darker color, less acidic flavor; measure precisely 3/4 cup (75g) after sifting to avoid dry, cakey cookies.
- High-Quality Chocolate:Incorporate dark (70-75% cacao) and semi-sweet (60% cacao) chocolate for complex flavor, fudginess; chop 4 ounces (113g) dark chocolate to 1/4-inch pieces for even melting.
- Brown Butter:Brown 1/2 cup (113g) unsalted butter in a light saucepan over medium heat 3-5 minutes until golden flecks appear, smelling nutty; immediately transfer to prevent burning, deepening the flavor.
- Room Temperature Eggs:Allow 2 large eggs to sit at room temperature for 30 minutes; this ensures better emulsification with chocolate mixture, which leads to smoother batter, chewier cookies.
Technique Tips
- Achieving the Crinkly Top:Vigorously whisk melted chocolate-butter, 1 cup (200g) granulated sugar, 1/2 cup (100g) brown sugar, and 2 eggs for 2 minutes until glossy, slightly thickened; this air incorporation forms the signature crackled surface.
- Precise Flour Measurement:Spoon 3/4 cup (90g) all-purpose flour into a measuring cup and level, not scooping, to prevent over-compacting; exceeding by 2 tablespoons results in tough, cakey cookies.
- Chilling the Dough:Refrigerate dough minimum 60 minutes, up to 24 hours; this allows flour to hydrate, fats to firm, preventing spreading and ensuring thicker, chewier cookies.
- Controlled Baking Environment:Bake cookies at 350°F (175°C) on middle rack 9-11 minutes; remove when edges are set, slight crackling appears, but centers are underbaked; they set as they cool.
Common Issues
- Cookies are too Flat/Greasy:If cookies spread excessively, butter too warm or chilling insufficient. Solution: Ensure browned butter cools to 70°F (21°C); chill dough at least 60 minutes. If spreading during baking, remove 5 minutes, then return.
- Cookies are Cakey and Dry:This results from overbaking or too much flour. Solution: Reduce baking time to 9-10 minutes, verify 350°F (175°C) with oven thermometer; precisely measure 3/4 cup (90g) flour by spooning and leveling.
- Lack of Shiny, Crinkly Top:The signature crinkle requires sufficient aeration of wet ingredients. Solution: After melting butter and chocolate, vigorously whisk 1 cup (200g) granulated sugar and 2 eggs for 2 minutes until mixture lightens, becomes thick and glossy.
- Cookies Stick to Baking Sheet:Happens without parchment paper or if removed too soon. Solution: Always line sheets with parchment paper or a silicone mat; let baked cookies cool on sheet for 10 minutes before transferring, as they are delicate when hot.
Common Mistakes to Avoid for Best Results
Common Mistakes
- Cakey, dry texture:
- Why it happens: This often results from either too much flour or overmixing the batter, which develops gluten. Excess flour absorbs crucial moisture, leading to a tough, cake-like crumb instead of a dense, fudgy one. Exact fix: Always measure flour precisely by spooning it into a measuring cup and leveling with a straight edge (like a knife), avoiding direct scooping. Once flour is added, fold gently with a spatula, scraping the bottom and sides of the bowl, until just combined and no streaks of dry flour remain (approximately 15-20 gentle folds).
- Flat, greasy cookies:
- Why it happens: Often caused by butter that’s too warm when mixed, or insufficient chilling of the dough. Warm butter melts too quickly during baking, causing the cookies to spread excessively, while insufficient chilling prevents the butter from re-solidifying, contributing to a flat, greasy texture. Exact fix: Ensure your melted butter is cooled to room temperature (around 70°F / 21°C) before incorporating it. Chill the dough for a minimum of 30 minutes, or ideally 1-2 hours in the refrigerator, until it is firm to the touch. If excessive spreading persists, add an additional 1-2 tablespoons of all-purpose flour to the dry ingredients.
- No crinkly top (lack of signature brownie look):
- Why it happens: The hallmark crinkly top forms from a delicate sugar crust created by properly aerated eggs and sugar, which then cracks during baking. Insufficient whisking of the eggs and sugar, or an imbalance in the sugar-to-flour ratio, prevents this crust from forming effectively. Exact fix: Vigorously whisk 2 large eggs, 1 cup (200g) granulated sugar, and 1/2 cup (100g) packed light brown sugar together for 3-5 minutes with an electric mixer (or 7-10 minutes by hand) until the mixture becomes pale, thick, and almost doubles in volume, and when lifted, it forms a slow-dissolving “ribbon” that holds its shape briefly on the surface.
Key Techniques
- Achieving the Perfect Butter-Chocolate Base:
- Gently melt 1/2 cup (113g) unsalted butter with 4 oz (113g) dark chocolate (60-70% cocoa solids) in a heatproof bowl set over a pot of simmering water (double boiler) or in 30-second bursts in the microwave, stirring until smooth and glossy. Remove from heat and allow to cool for 10-15 minutes, until it’s warm to the touch (around 80-90°F / 27-32°C), not hot. This prevents scrambling the eggs later and ensures a smooth batter.
- Gentle Dry Ingredient Incorporation:
- Sift together 3/4 cup (90g) all-purpose flour, 1/4 cup (22g) unsweetened cocoa powder, 1/2 teaspoon baking powder, and 1/4 teaspoon salt into a bowl. Gradually add these sifted dry ingredients to the wet mixture in two additions. Using a flexible spatula, fold gently, scraping the bottom and sides of the bowl, until just combined and no lumps remain. Stop mixing immediately when no dry flour is visible (usually within 15-20 folds) to prevent gluten development and tough cookies.
- Optimal Baking for Fudginess:
- Preheat your oven to 350°F (175°C). Drop dough by tablespoonfuls onto a parchment-lined baking sheet, spaced 2 inches apart. Bake for 10-12 minutes. The cookies are done when the edges are set and lightly crinkled, but the centers still look slightly soft, gooey, and a bit underbaked. A toothpick inserted into the center should come out with moist crumbs, not wet batter. Overbaking will result in dry, cakey cookies. Allow to cool on the baking sheet for 2 minutes before transferring to a wire rack to cool completely.
