Browned Milk-Powder Shortbread with Cocoa Nib Edges Recipe
Follow the tray sizes, portions and baking intervals in the instructions below.
Total time includes hands-on preparation, required chilling or resting, whole-batch cooking, cooling and finishing.
Kitchen tools you’ll need
- skillet
- sieve
- bowl
- spatula
- knife
- two 13 x 18-inch half sheets
- parchment
- rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Toast and mix
- Toast and mix: Stir milk powder in a dry skillet over low heat 4–6 minutes until uniformly tan, then cool 15 minutes and sift out lumps. Stir butter and sugar smooth; mix in flour, toasted milk powder and salt until cohesive.
Shape and chill
- Shape and chill: Form a log 8 inches long and about 1 3/4 inches wide. Roll the surface in finely chopped cocoa nibs, pressing to attach. Wrap and chill 90 minutes. Slice 24 coins about 1/3 inch thick.
Bake the whole batch
- Bake the whole batch: Heat oven to 325°F (165°C) conventional or 300°F (150°C) fan. Use two parchment-lined 13 x 18-inch half sheets, 12 cookies per sheet, spaced at least 1 inch apart. Bake one tray at a time on the middle rack for 18–22 minutes, turning front to back halfway; keep the waiting tray refrigerated. Edges and bases should be pale gold and the centers dry. Whole-batch oven time is 44 minutes for both trays.
Cool the cookies
- Cool the cookies: Rest 10 minutes on each tray, then cool 20 minutes on a rack before packing; the 30-minute cooling allowance includes the tray rest.
Timing and scaling
- Timing and scaling: 30 min hands-on + 105 min required chill/rest + 44 min whole-batch oven baking + 30 min cooling/setting = 209 min. Cooling includes tray/pan rests and runs from the final tray; earlier-tray cooling may overlap later baking. Ingredient warm-up and frozen-dough thawing are extra; preheat during shaping/chilling. Scale ingredients and US equivalents, not oven temperature, piece sizes or per-tray bake time; extra trays extend the whole-batch time.
Chef’s Science & Pro Tips
Ingredient science
Toasted milk powder adds dairy proteins and dry solids without extra butterfat; chopped nibs form a firm particulate edge.
Technique & texture
Toast milk powder slowly and stir constantly; dark specks mean burnt milk solids, not desirable brown butter.
Finishing & serving
Serve at room temperature for the fullest toasted-dairy aroma and let the nib edges cool before stacking.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 5 days | Up to 5 days. Seal fully cooled cookies airtight in a cool dry room. Separate layers with parchment; keep away from moist treats. |
| Refrigeration | up to 7 days | Unnecessary; up to 7 days if needed. Baked refrigeration is unnecessary for this formula; use only if the room is warm. Seal airtight to prevent condensation and odors. |
| Raw freezing | 1 month | Up to 1 month. Freeze the unfilled dough tightly wrapped. Thaw overnight in the refrigerator, then shape and complete the stated chill. Thawing time is additional. |
| Baked freezing | 2 months | Up to 2 months. Freeze completely cooled cookies airtight with parchment between layers. Thaw sealed at room temperature for 1–2 hours. |
| Restoring | As described | Optional 3–5 minutes. Refresh plain cookies at 300°F (150°C) conventional or 275°F (135°C) fan for 3–5 minutes, then cool 20 minutes before sealing. This extra time is outside fresh-batch timings. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.
