Chocolate Truffle Christmas Shortbread Bars 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
- 8-inch square metal pan
- parchment sling
- mixer
- small saucepan
- heatproof bowl
- spatula
- sieve
- cooling rack
- sharp knife
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Mix the base
- Mix the base: Heat oven to 350°F (175°C) conventional or 325°F (165°C) fan. Line an 8-inch square metal pan with a parchment sling. Beat base butter and sugar briefly, add base flour and salt and press into an even layer. Dock lightly.
Bake
- Bake: Bake the single pan 23–28 minutes until the surface is pale golden and edges are deeper gold. Whole-batch oven bake is 28 minutes. Cool in the pan on a rack for 45 minutes before topping.
Emulsify ganache
- Emulsify ganache: Heat cream in a small saucepan just until steaming. Pour onto finely chopped chocolate and wait 2 minutes. Stir slowly from the center until glossy, then incorporate ganache butter. Spread over the cooled base. The 2-minute undisturbed wait is included in cool, while heating and stirring are included in active.
Set
- Set: Refrigerate 120 minutes until the ganache is firm. Allow the chilled slab to stand 10 minutes before cutting; chill is separate from 45 + 2 + 10 = 57 minutes cooling and resting.
Finish
- Finish: Lift the slab, dust with cocoa and cut a 4 x 4 grid for exactly 16 bars using a warm, dry knife. Timing assumes softened base butter and room-temperature ganache butter; allow extra warm-up if needed. Scale ingredients without changing layer depth, chocolate percentage or oven temperature.
Chef’s Science & Pro Tips
Ingredient science
Use 60–70% dark chocolate: milk or white chocolate needs a different cream ratio to set.
Technique & texture
Stir from the center after the short wait to make a glossy emulsion without whipping in air.
Finishing & serving
A warm dry knife makes clean cuts; water droplets on the blade mark the cocoa finish.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 2 hours | Up to 2 hours for serving. Serve filled bars in small batches; return to the refrigerator promptly. Reduce to 1 hour if the room is above 90°F (32°C). |
| Refrigeration | 4 days | Up to 4 days. Keep filled bars airtight at 40°F (4°C) or below. Plain shortbread needs no refrigeration; the assembled filling is why this recipe specifies chilled storage. Separate layers with parchment. |
| Raw freezing | 1 month | Up to 1 month, dough only. Freeze only the shortbread dough, well wrapped; thaw covered overnight in the refrigerator, then shape and complete the recipe's full bake. Make fillings fresh; do not freeze raw egg custard or raw frangipane in assembled bars. |
| Baked freezing | 1 month | Up to 1 month. Freeze fully cooled filled bars airtight between parchment layers. For sandwiches, freezing unfilled baked halves and adding fresh filling gives a crisper crumb. Thaw filled items covered overnight in the refrigerator. |
| Restoring | 2 hours | Overnight refrigerated thaw; 10–20 minutes before serving. Thaw filled items covered in the refrigerator. Let a serving portion stand 10–20 minutes to soften, keeping the total room-temperature exposure within 2 hours. Do not oven-reheat filled items; add fresh powdered sugar or cocoa after thawing where used. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.
Nutrition
Approximate values per portion from the listed ingredient weights divided into 16 equal portions. Includes required fillings and finishes. Brands, unused coatings and actual portion size affect the estimate.
Frequently Asked Questions
Is the ganache baked?
No; only the shortbread base is baked. The ganache sets during the two-hour refrigerator stage.
Can I use milk chocolate with the same cream amount?
No; the 170 g chocolate to 80 g cream ratio is specified for 60–70% dark chocolate.
Why cool the base before topping?
A hot base can melt the ganache butter unevenly and delay a firm, clean layer.
