Dark Chocolate Cherry Crunch Cookie
Tangy, chewy, bright, and crunchy. A dark chocolate cherry cookie built on a non-cocoa base — melted butter, buttermilk powder, and lemon zest keep things bright while Valrhona Manjari, sour cherries, hazelnuts, and Frosted Flakes do everything else.
Ingredients
Instructions
Melt the butter
Melt the butter in a small saucepan or in the microwave. Set aside to cool for 5–10 minutes until warm but not hot. You're melting, not browning — pull it off heat as soon as it's liquid.
Build the base
In a large bowl, whisk together the warm melted butter, light brown sugar, granulated sugar, and buttermilk powder until fully combined and uniform. The buttermilk powder should dissolve completely into the fat — no dry clumps.
Add eggs, vanilla, and zest
Add the whole egg, egg yolk, vanilla extract, and lemon zest. Whisk vigorously for 60–90 seconds until the mixture is thick, glossy, and slightly lightened — it should fall from the whisk in thick ribbons. The extra yolk adds richness without making the cookie cakey; the lemon zest is a background note, not a dominant flavor.
Add the dry ingredients
In a separate bowl, whisk together the flour, baking soda, baking powder, fine sea salt, and espresso powder. Add the dry ingredients to the wet mixture and stir with a spatula until just combined — stop as soon as no dry streaks remain. Don't overmix. The espresso won't taste like coffee; it sharpens the chocolate without announcing itself.
Fold in the mix-ins
Add the Valrhona Manjari chunks, chopped sour cherries, and hazelnuts. Fold until evenly distributed. Add the Frosted Flakes last and fold in just 2–3 times — enough to incorporate them without crushing them further. The crunch is the point; don't lose it here.
Chill
Cover the bowl and refrigerate for 2 hours. This lets the flour hydrate fully, firms the butter to control spread, and lets the flavors settle into each other. Don't skip it.
Portion and top
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment. Scoop the chilled dough into 60g portions — this recipe yields approximately 15 cookies. Roll loosely into balls without overworking the dough. Space them at least 2 inches apart on the sheet and finish each one with a generous pinch of flaky salt on top.
Bake and cool
Bake for 10–11 minutes. The edges should be set and the centers should still look slightly underdone — pull them at that point. They finish on the pan. Cool on the baking sheet for 5 minutes before transferring to a rack.
Baker's Notes
- Valrhona Manjari is a 64% dark chocolate with a distinctly fruity, berry-forward character — it was chosen specifically to amplify the sour cherry rather than compete with it. A standard 60–70% dark chocolate works, but the result will be rounder and less bright.
- The buttermilk powder is non-negotiable. It's what gives this cookie its tang and tenderness from the inside out — a different texture than you get from browned butter or extra yolks alone. Find it in the baking aisle or online; it keeps for months in a sealed container.
- Lightly crushed means broken into rough shards, not ground into dust. Put the Frosted Flakes in a zip-lock bag and press once with the heel of your hand. You want pieces, not powder.
- The Frosted Flakes will soften slightly as the cookies sit. These are best in the first 24 hours, when the contrast between the crispy cereal and the chewy center is at its sharpest.
- The lemon zest is subtle by design — it brightens without taking over. It registered as "citrus" with one taster in the Episode 5 blind tasting and may have created unexpected complexity for others. If you want a cleaner chocolate-cherry read, leave it out.
