Librae-Style Flourless Chocolate Cookies

Provenance: Hybrid of Bright Moment Co. — Fudgy Flourless Brownie Cookies and Sugar Spun Run — Flourless Chocolate Cookies, aimed at cloning the exterior crackle of BMC with the melt-in-mouth interior of SSR. Further modifications are dropping the baking powder removed and adding vanilla and espresso powder.

Yield: 12 cookies · Active: 20 min · Bake: 10–12 min · Oven: 350°F / 175°C

Method

1. Preheat oven to 350°F (175°C). Line a large baking sheet with parchment paper.
2. In a saucepan over low heat (or in 25-second microwave bursts), melt the butter, then add the chopped chocolate, stirring with a spatula until smooth. Remove from heat. Stir in the espresso powder until fully dissolved. Set aside to cool until just warm — not hot — to the touch.
3. In a large bowl, combine the eggs, granulated sugar, vanilla, and salt. Whip with an electric mixer on medium-high for 3–4 minutes, until the mixture is smooth, pale, and ribboned. This step is non-negotiable — it is the entire structural backbone now that flour is gone.
4. With the mixer on low (or by hand with a spatula), drizzle in the chocolate-butter mixture and mix until just combined.
5. Sift the cocoa powder and cornstarch over the batter. Fold gently with a spatula until uniform, with no streaks of dry ingredient remaining.
6. Fold in the chocolate chunks.
7. Let the batter cool in the fridge, ideally flattened out to ensure even cooling.
8. Scoop 60g portions onto the prepared sheet, spaced widely. Sprinkle with flaky salt.
9. Bake for 12–15 minutes, until tops are crackled and the center top is just set.
10. Let completely cool, ideally resting overnight.
