Ingredients
- 1 pound Pecans, halved (Toast until fragrant)
- 6 tablespoons Unsalted butter (Cut into pieces for the butterscotch mixture)
- 1 cup Demerara sugar (Can substitute dark brown sugar)
- 1 cup Heavy cream (35% fat) (Divided: ½ cup for the hot mixture, ½ cup added after)
- 2.5 tablespoons Light corn syrup (Adds shine and prevents crystallization)
- 4 Large eggs (Temper with hot mixture to avoid curdling)
- 1 tablespoon Pure vanilla extract
- 1 teaspoon Kosher salt (If using regular table salt, use ½ tsp)
- 1 tablespoon Unsweetened cocoa powder (Adds color and subtle depth)
- 1 teaspoon Instant coffee granules (Provides bitterness without coffee flavor)
- 1 sheet Shortcrust pastry dough (pre‑made) (Enough to line a 9×13" slab pan; keep cold until used)
- 1 cup Dried beans or rice (pie weights) (Use to keep crust flat during blind bake)
- 1 sheet Heavy‑duty aluminum foil (Liners for blind baking)
Instructions
Toast pecans
Preheat oven to 350°F. Spread 1 lb pecan halves in a single layer on a baking sheet and toast for 10 minutes, stirring once halfway through.
Time: PT10M
Temperature: 350°F
Roll out crust
On a lightly floured surface, roll the pre‑made shortcrust dough to a rectangle slightly larger than the 9×13" slab. Trim excess, then chill on a sheet of parchment for 5 minutes.
Time: PT15M
Freeze crust
Place the rolled crust in the baking slab, gently press into the bottom and up the sides, then transfer the slab to the freezer for 5 minutes to firm the layers.
Time: PT5M
Blind‑bake crust (high heat)
Increase oven to 400°F. Line the chilled crust with heavy‑duty foil, fill with pie weights, and bake for 20 minutes until the edges turn golden.
Time: PT20M
Temperature: 400°F
Blind‑bake crust (low heat)
Remove foil and weights, lower oven temperature to 300°F, and bake an additional 15 minutes until the bottom looks dry and lightly golden.
Time: PT15M
Temperature: 300°F
Prepare butterscotch base
In a medium saucepan over medium heat, combine 1 cup demerara sugar, 6 Tbsp butter, and 2.5 Tbsp light corn syrup. Stir until sugar dissolves, then bring to a gentle boil. Cook, stirring occasionally, until the mixture turns a medium‑gold honey color (about 7 minutes).
Time: PT7M
Finish hot mixture
Remove the saucepan from heat, stir in the remaining ½ cup heavy cream. The mixture will sputter—use caution.
Time: PT3M
Temper eggs
In a separate mixing bowl, whisk 4 large eggs. Slowly drizzle about ¼ cup of the hot butterscotch mixture into the eggs while whisking constantly, then whisk the tempered egg mixture back into the saucepan.
Time: PT5M
Flavor the custard
Stir in 1 Tbsp vanilla extract, 1 tsp kosher salt, 1 Tbsp cocoa powder, and 1 tsp instant coffee granules. Whisk until fully incorporated and the mixture is smooth.
Time: PT3M
Assemble pie
Evenly scatter the toasted pecans over the pre‑baked crust. Pour the custard filling over the nuts, stopping just below the rim (about ¾ of the filling volume). Smooth the top with a spatula.
Time: PT5M
Bake filled pie
Return the slab to the oven set at 300°F and bake for 20 minutes, or until the custard is puffed, lightly browned, and a knife inserted near the edge comes out clean.
Time: PT20M
Temperature: 300°F
Cool and serve
Remove the pie from the oven and let it cool on a wire rack for at least 30 minutes before slicing into squares.
Time: PT30M

Equipment Needed

- Rolling pin
- Bench scraper
- Paring knife
- Heavy‑duty aluminum foil
- Dried beans or rice (pie weights)
- Medium‑sized saucepan
- Whisk
- Mixing bowl
- Cooling rack
- Timer
Critical Steps — Do Not Skip
- Toasting pecans evenly
- Keeping the crust cold before blind‑baking
- Blind‑baking at high heat then lowering temperature
- Tempering the eggs into the hot butterscotch mixture
- Ensuring the custard is puffed and set before removing from oven
Chef Tips from the Video
- Use a piece of parchment under the foil when blind‑baking to prevent sticking.
- A pinch of instant coffee balances the sweetness without imparting coffee flavor.
- If you don’t have a Made In slab, a standard 9×13" glass dish works, but watch the crust for uneven browning.
Troubleshooting
Crust shrinks during blind‑bake leaving gaps.
Chill the dough longer before baking and press the sides back against the slab after the first bake.
Filling is runny after baking.
Bake an additional 5‑10 minutes at 300°F; ensure the custard reaches a puffed, slightly browned surface.
Pecans become soggy.
Toast pecans well and add them after the crust is fully baked; avoid over‑mixing the filling.
Storage
Refrigerator: Cover tightly; lasts up to 3 days.
Freezer: Wrap each portion in plastic wrap and foil; freeze up to 1 month.
Room temperature: Not recommended; may become soggy.
Make-Ahead Tips
- Blind‑bake the crust up to step 5 and let it cool; store wrapped in the fridge for up to 2 days.
- Prepare the butterscotch custard, let it cool, then refrigerate; bake the filled pie on the day of serving.
