Chocolate Orange Marmalade Shortbread Sandwiches 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
- saucepan
- fine sieve
- bowl
- pastry blender
- two 13 x 18-inch half sheets
- parchment
- knife
- rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Prepare and rub the dough
- Prepare and rub the dough: Hard-boil one egg by bringing it to a boil covered with cold water, standing covered off heat 12 minutes and cooling in cold water 10 minutes. Reserve the white for another use and sieve the yolk. Rub butter into flour, cocoa and salt until sandy, then stir in sugar and sieved yolk; press just until cohesive.
Shape and chill
- Shape and chill: Divide dough into 32 equal portions, about 15 g each. Press between parchment into flat 2-inch rounds, about 1/4 inch thick. Refrigerate 30 minutes until firm. The cooked-yolk cooling adds 10 minutes, for 40 minutes required cooling/chilling before baking.
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, 16 discs 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. Tops should be matte and rims firm; inspect bases for dryness because cocoa hides browning. Whole-batch oven time is 44 minutes for both trays.
Cool and fill
- Cool and fill: Rest 10 minutes on trays and 20 minutes on a rack. Chop any large rind pieces in the marmalade. Spread about 6 g, a thin teaspoon, on each of 16 bottoms and cap with remaining discs; keep filling 1/8 inch inside the rim.
Timing and scaling
- Timing and scaling: 35 min hands-on + 40 min required chill/rest + 44 min whole-batch oven baking + 30 min cooling/setting = 149 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
Cooked yolk and rubbed mixing produce compact cocoa shells without raw egg binding; a thick preserve supplies a distinct moist joining layer.
Technique & texture
Sieve the cooked yolk finely and chop thick marmalade rind so both shell and filling remain smooth enough for thin sandwiches.
Finishing & serving
Fill close to serving and use filled sandwiches within 2 days at cool room temperature as marmalade gradually softens the shells.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 2 days | Up to 2 days. Seal fully cooled filled cookies airtight in a cool dry room. Separate layers with parchment; the filling gradually softens the crumb. |
| 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. Prepare the filling fresh. Thawing time is additional. |
| Baked freezing | 2 months | Up to 2 months. Freeze unfilled cookie shells airtight with parchment between layers. Thaw sealed at room temperature for 1–2 hours. Fill after thawing. |
| Restoring | As described | Serve after thawing. Do not oven-refresh the assembled or coated cookies. Thaw shells, prepare fresh filling, then assemble as directed. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.
