Chocolate-Dipped Whipped Peanut Butter Shortbread 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
- mixing bowl
- mixer
- kitchen scale
- two 13 x 18-inch half sheets
- parchment
- fork
- wide spatula
- cooling rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Whip and mix
- Whip and mix: Beat butter and sugar 4 minutes until pale and airy, scraping twice. Beat in peanut butter briefly until smooth. Sift flour, cornstarch and salt and mix on low just until combined; stop before the foam collapses.
Shape and chill
- Shape and chill: Divide all dough into 24 portions about 15 g each. Roll lightly and press with a fork into 1 3/4-inch rounds about 3/8 inch thick without flattening out all the air. Chill 30 minutes.
Bake the whole batch
- Bake the whole batch: Heat oven to 300°F (150°C) conventional or 275°F (135°C) fan. Place 12 rounds per parchment-lined 13 x 18-inch half sheet, at least 1 inch apart. Bake one sheet at a time for 18–22 minutes until surfaces set and bases are faint gold, keeping waiting tray chilled. Whole-batch oven time is up to 44 minutes.
Cool and dip
- Cool and dip: Rest 10 minutes on trays and 20 minutes on a rack. Melt chocolate in short 20-second microwave bursts, stirring often. Dip half of each cold cookie and rest on parchment 30 minutes to set. Cooling/setting totals 60 minutes including tray rest.
Timing and scaling
- Timing and scaling: 30 min hands-on + 30 min required chill/rest + 44 min whole-batch oven baking + 60 min cooling/setting = 164 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
Whipping supplies air and cornstarch reduces gluten; the modest peanut-butter fraction differs from dense nut-butter shortbread.
Technique & texture
Add peanut butter only after whipping the dairy butter; heavy nut paste at the start limits aeration.
Finishing & serving
Let the half-dip set before handling; these airy cookies are more fragile than compact peanut-butter rounds.
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; let the coating set before packing. |
| 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 uncoated baked cookies airtight with parchment between layers. Thaw sealed at room temperature for 1–2 hours. Apply the finish after thawing. |
| 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.
