Brown-Butter Shortbread Jammers 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
- light saucepan
- scale
- bowls
- two standard 12-well muffin pans
- teaspoon
- offset spatula
- rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Make dough and crumble
- Make dough and crumble: Brown the 127 g butter in a light pan, stirring until solids are amber. Scrape into a bowl, weigh 113 g finished butter, topping up with water only if needed, and cool 40 minutes until spreadable. Mix with dough sugar, both dough flours and salt until cohesive. Separately rub cold topping butter into topping flour and sugar to form small dry crumbs.
Portion the jammers
- Portion the jammers: Lightly grease two standard 12-well muffin pans. Divide dough into 24 portions, about 13 g each, and press into flat 2-inch discs in the wells without building cup walls. Add 1/2 tsp jam to each center; distribute crumble around the jam, keeping the center visible. Chill 20 minutes.
Bake the whole batch
- Bake the whole batch: Heat oven to 325°F (165°C) conventional or 300°F (150°C) fan. Bake one 12-well muffin pan at a time on the middle rack for 22–25 minutes until crumble is golden and bases are firm; keep waiting pan chilled. Whole-batch oven time is up to 50 minutes for two pans.
Cool and release
- Cool and release: Rest 15 minutes in each pan, loosen carefully with a small offset spatula, then cool 25 minutes on a rack. The 40-minute allowance includes pan rest; jam must be fully cool before packing.
Timing and scaling
- Timing and scaling: 35 min hands-on + 60 min required chill/rest + 50 min whole-batch oven baking + 40 min cooling/setting = 185 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
Muffin wells support a low-water shortbread disc while browned butter and rye create a distinct base beneath the jam and dry crumb topping.
Technique & texture
Keep the crumble at the rim and the jam in the center; an overloaded center bubbles over and sticks to the pan.
Finishing & serving
Serve once the jam is cool; keep jammers separate from crisp unfilled cookies because the jam softens them.
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 completely cooled cookies airtight with parchment between layers. Thaw sealed at room temperature for 1–2 hours. |
| Restoring | As described | Serve after thawing. Do not oven-refresh the assembled or coated cookies. Serve once thawed; reseal unused portions. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.
