Step-by-Step Instructions

Step 1: Prep the pan and oven

Heat the oven to 350°F (175°C). Lightly grease a 9-inch tart pan with a removable bottom. Place the pan on a rimmed baking sheet to make transferring easier.

Step 2: Make and bake the pretzel crust

In a food processor, pulse the salted pretzels to fine, sandy crumbs. You want a uniform crumb with no large shards for a sturdy crust. In a bowl, combine pretzel crumbs, melted butter, and brown sugar until the mixture holds together when pressed.

Press the mixture firmly into the bottom and up the sides of the tart pan. Use the bottom of a measuring cup to compact it well. Bake for 10–12 minutes until fragrant and just set. Cool completely on a rack, 30–40 minutes. For a faster set, chill the crust for 15 minutes after it cools to room temperature.

Step 3: Cook the butterscotch base

In a heavy-bottomed medium saucepan over medium heat, melt the butter. Stir in the dark brown sugar and kosher salt. Cook, stirring, until the mixture is glossy, bubbling, and smells like toffee, about 3–4 minutes. Carefully whisk in the heavy cream (it will bubble vigorously), then whisk in the milk. Bring just to a simmer, whisking to dissolve any sugar bits. Keep the heat on low.

Step 4: Temper the yolks and thicken

In a medium bowl, whisk the egg yolks with the cornstarch until smooth. Slowly ladle about 1 cup of the hot butterscotch mixture into the yolks while whisking constantly to temper. Pour the tempered yolk mixture back into the saucepan.

Cook over medium heat, stirring constantly with a heatproof spatula and whisk, scraping the corners of the pan, until the pudding thickens, large bubbles plop, and it reads 180–185°F (82–85°C) on an instant-read thermometer, 2–4 minutes. Remove from heat and whisk in the vanilla and bourbon (if using). Taste and adjust salt if needed.

Step 5: Strain, fill, and chill

Strain the hot pudding through a fine-mesh sieve into a clean bowl to catch any bits, then immediately pour into the cooled pretzel crust. Tap the pan gently on the counter to level and release air bubbles. Press plastic wrap directly onto the surface of the pudding to prevent a skin. Chill until fully set, at least 4 hours or overnight.

Step 6: Whip, garnish, and serve

In a cold mixing bowl, whip the heavy cream, powdered sugar, vanilla, and a pinch of salt to soft peaks (about 2–3 minutes with a hand mixer on medium-high). Remove the plastic wrap from the tart and spoon or pipe the cream over the set pudding in swoops. Finely grate the dark chocolate over the top and finish with a few flakes of sea salt if you like. Slice with a hot, dry knife (dip in hot water and wipe between cuts) and serve.

Pro Tips

• Weigh the pretzels if possible for the most reliable crust texture; fine crumbs pack and slice more cleanly.
• Dark brown sugar gives deeper butterscotch flavor; if using light brown sugar, add 1 teaspoon molasses.
• Keep the pudding moving: constant stirring prevents scorching and keeps the custard silky.
• Always strain the pudding—it takes 30 seconds and guarantees a smooth, lump-free filling.
• For extra crunch insurance, brush a thin layer of melted dark chocolate on the cooled crust, then fill once it sets.

Variations

• Banoffee-Style: Add sliced ripe bananas over the cooled crust before pouring in the pudding.
• Mocha Scotch: Whisk 1 teaspoon espresso powder into the hot pudding off heat, then add vanilla.
• Nutty Crunch: Top the whipped cream with toasted chopped pecans or hazelnuts along with the grated chocolate.

Storage & Make-Ahead

The baked crust can be made 2 days ahead; store covered at room temperature (or freeze up to 1 month). The filled, wrapped tart (without whipped topping) keeps 2 days in the refrigerator. Add whipped cream and chocolate within 4 hours of serving for best texture. Leftovers keep, covered and refrigerated, up to 3 days; the crust will gradually soften. Freezing is not recommended, as starch-thickened custards can weep once thawed.
