Pecan Pie Shortbread Squares 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
- bowls
- whisk
- thermometer
- knife
- rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Mix crust and filling
- Mix crust and filling: Stir base butter and sugar smooth, add base flour and salt until cohesive. Separately whisk eggs, brown sugar, maple syrup, cooled topping butter and topping flour smooth, then fold in pecans. Do not whip foam into the filling.
Press the crust
- Press the crust: Line an 8-inch square metal pan with parchment overhang. Press all dough level and prick lightly. No chilling is required.
Bake twice
- Bake twice: Heat oven to 350°F (175°C) conventional or 325°F (165°C) fan. Bake crust 18–20 minutes until pale gold. Stir filling again and pour over hot crust, spreading nuts evenly. Bake another 28–35 minutes until the edge is firm, the center no longer ripples as liquid, and center filling reaches 170°F (77°C). Total oven time is up to 55 minutes.
Cool and slice
- Cool and slice: Cool in pan on a rack 90 minutes, then refrigerate 60 minutes until fully set. Lift and cut 16 squares with a sharp wiped knife. Cooling/setting totals 150 minutes and includes the pan rest and required final chill.
Timing and scaling
- Timing and scaling: 30 min hands-on + 0 min required chill/rest + 55 min whole-batch oven baking + 150 min cooling/setting = 235 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
Egg and flour set a syrup-rich pecan layer over parbaked shortbread; this differs structurally from condensed-milk caramel or a Florentine nut glaze.
Technique & texture
Judge the center filling rather than toasted nut color; nuts can brown before the egg-rich pie layer sets.
Finishing & serving
Keep leftovers refrigerated; bring individual squares to room temperature covered for 15 minutes before serving if desired.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 2 hours | Serve within 2 hours. Keep chilled except for serving; return leftovers promptly to refrigeration. |
| Refrigeration | 4 days | Up to 4 days. Store airtight at 40°F (4°C) or colder. Keep covered while bringing a serving portion to room temperature. |
| 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 | 1 month | Up to 1 month. Freeze completely cooled bars airtight with parchment between layers. Thaw covered overnight in the refrigerator. |
| Restoring | As described | Serve after thawing. Do not oven-refresh the assembled or coated bars. 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.
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.
