Mocha Cookies with Dark Chocolate and Pistachios

A fun mocha flavored cookie, I like to cut the cookies into strips and then snap them apart into bite size pieces. It gives the cookies a more casual look but if you prefer, feel free to cut them with a sharp knife into squares. If you aren’t sensitive to gluten, feel free to leave out all the whole grain flours and just use 1 3/4 cups (245 g) all-purpose flour in their place.

Why it works: Chia and teff share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and 6 recipes mention both. Both carry coumarin, which smells sweet, hay. The science ↓

Ingredients

Contains: egg, milk, wheat, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Preheat the oven to 350°F (177°C). Line a 9x13-inch (23x33 cm) pan with parchment paper, leaving overhang on the long sides.

  2. Melt the butter in a saucepan over low heat, then remove from heat. Whisk in the dark brown sugar, espresso powder, salt, egg, and vanilla extract until smooth.

  3. Whisk the cornstarch, teff flour, sweet rice flour, buckwheat flour, mesquite flour, cocoa powder, and chia seeds together in a separate bowl.

  4. Fold the dry flour mixture into the butter mixture with a spatula until just combined and no dry streaks remain.

  5. Chop the pistachios and dark chocolate into rough pieces. Fold them into the dough, then press the dough evenly into the prepared pan.

  6. Chill the pan in the refrigerator for 20 minutes to firm the dough.

  7. Bake for 18 to 20 minutes, until the top looks set and the edges are firm. Sprinkle the flaky sea salt over the top while still warm.

  8. Cool the pan completely on a rack, then lift out using the parchment and cut into 48 squares.

Fit is the average pairing score against egg, chia, teff, flour, rice, buckwheat, cocoa powder. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
