Ingredients
  

  • 200 g Dark chocolate, 60 to 70 percent cacao Roughly chopped, good quality bar not chips
  • 3 tbsp Unsalted butter 45g
  • 2 large Eggs Room temperature
  • 1 large Egg yolk Room temperature, adds fudginess
  • ¾ cup Granulated sugar 150g
  • ¼ cup Light brown sugar 50g
  • 1 tsp Pure vanilla extract
  • ½ cup All-purpose flour 65g
  • 2 tbsp Unsweetened cocoa powder For extra depth
  • ½ tsp Baking powder
  • ¼ tsp Fine sea salt
  • ½ cup Chocolate chips or chunks 85g, optional for extra chocolate pockets
  • - Flaky sea salt For topping, added before baking

Equipment

  • 1 Double boiler or microwave-safe bowl For melting chocolate safely
  • 1 Stand Mixer or Hand Mixer Essential for beating eggs 3 to 4 minutes
  • 2 Baking sheets, rimmed Line with parchment paper
  • 1 Parchment Paper Prevents sticking
  • 1 Cookie scoop For evenly sized cookies
  • 1 Wire Cooling Rack For final cooling after pan rest
  • 1 Rubber spatula For gentle folding, never a whisk

Method
 

Melt the Chocolate and Butter
  1. Low Heat, Then Cool Completely: Combine the chopped dark chocolate and butter in a heatproof bowl. Melt together over a double boiler or in the microwave in 20-second bursts at 50 percent power, stirring between each interval until completely smooth. Remove from heat and let the mixture cool for a full 10 minutes before using. The chocolate must feel pleasantly warm but not hot when it touches the eggs. Hot chocolate scrambles the eggs and deflates the foam you are about to build.

Beat the Eggs and Sugars
  1. Beat Until Pale, Thick, and Ribbony: Place the room temperature eggs, egg yolk, both sugars, and vanilla extract in a large bowl. Beat with a stand mixer or hand mixer on high speed for a full 3 to 4 minutes. Set a timer and do not stop early. The mixture is ready when it has doubled in volume, turned very pale and creamy, and falls in thick, slow ribbons from the lifted beater. This foam is what creates the crinkle top, and under-beating is the number one reason brownie cookies come out flat.

Fold In the Chocolate
  1. Gentle Strokes to Keep the Foam: Pour the cooled chocolate mixture into the beaten egg mixture. Fold together with a rubber spatula using slow, sweeping motions from the bottom of the bowl upward. Stop the moment no chocolate streaks remain. Do not stir vigorously or the foam collapses

Add the Dry Ingredients
  1. Fold Until Just Combined: Sift the flour, cocoa powder, baking powder, and salt directly into the chocolate batter. Fold gently with the spatula until no dry flour streaks remain. Fold in the chocolate chips if using. The batter will look loose and shiny, almost like pourable brownie batter. This is correct.

Rest the Batter
  1. 10 Minutes to Firm Up: Let the batter rest at room temperature for 10 minutes. It thickens slightly as the chocolate continues to set, making it much easier to scoop into neat rounds. If the kitchen is very warm and the batter still looks too loose, refrigerate for an additional 10 to 15 minutes before scooping.

Scoop and Bake
  1. Space Well, Watch Carefully: Preheat the oven to 350°F (175°C). Line baking sheets with parchment. Scoop the rested batter into rounds of about 1.5 tablespoons each, spacing them at least 2.5 inches apart. Sprinkle a small pinch of flaky sea salt on top of each cookie. Bake for 10 to 12 minutes until the edges look set and the tops are shiny and crinkled but the centers still look soft and slightly glossy. Start checking at 10 minutes.

Cool on the Pan
  1. Wait the Full 10 Minutes: Remove from the oven and leave the cookies on the pan for at least 10 full minutes before moving. Brownie cookies are very fragile when hot and will fall apart if transferred too soon. They firm up completely as the chocolate re-sets during cooling.

Serve
  1. Best Within the First Hour: Transfer carefully to a serving plate. These brownie cookies are at their best eaten within an hour of baking when the edges are still slightly crisp and the centers are at their most fudgy.

Notes

  • Quality chocolate makes a real difference here. This recipe has very few ingredients and chocolate is the primary flavor. A good 60 to 70 percent dark chocolate bar produces a noticeably better cookie than low-quality baking chips.
  • Beat the eggs for the full 3 to 4 minutes. This is the single most important step. Under-beating produces flat, crinkle-free cookies. Set a timer and do not stop early.
  • Cool the chocolate before adding to eggs. Hot chocolate scrambles eggs and collapses the foam. The bowl should feel warm but comfortable to touch, not hot.
  • Rest the batter before scooping. 10 minutes of rest firms the batter enough to hold its shape. Skipping this step causes excessive spreading.
  • Pull out before they look done. Centers should still look soft and slightly glossy when you remove from the oven. They firm up to fudgy perfection as they cool on the pan.
  • Cool completely on the pan. At least 10 minutes before moving. These cookies are very fragile when hot.
  • Do not refrigerate baked cookies. This dries them out. Store at room temperature in an airtight container up to 3 days.
  • Freeze raw scooped batter for up to 2 months. Bake from frozen, adding 2 to 3 extra minutes.
  • UK/Australia notes: "All-purpose flour" equals plain flour. "Baking powder" is the same term. "Flaky sea salt" is available as Maldon or similar.
  • Nutrition values are estimates and vary based on chocolate percentage and whether chocolate chips are included.
