Full Ingredients

Buttery Saltine Crust

• 6 oz (170 g) saltine crackers, finely crushed (about 55 crackers)
• 10 tbsp (140 g) unsalted butter, melted and slightly cooled
• 3 tbsp (38 g) granulated sugar

Brown-Sugar Sour Cream Filling

• 1 cup (220 g) packed light brown sugar
• 3 tbsp (24 g) all-purpose flour
• 1/4 tsp fine sea salt
• 3 large eggs, room temperature
• 1 1/2 cups (360 g) full-fat sour cream, room temperature
• 1 tbsp fresh lemon juice
• 1 1/2 tsp pure vanilla extract

Cinnamon-Sugar Finish & Optional Garnish

• 1 tbsp (12 g) granulated sugar
• 1/2 tsp ground cinnamon
• Small pinch flaky sea salt (optional)
• Softly whipped cream, for serving (optional)

Step-by-Step Instructions

Step 1: Preheat and prepare your pan

Place a rack in the center of the oven and heat to 350°F (175°C). Lightly butter a 9-inch standard pie plate (not deep-dish) to help the crust adhere. Set aside.

Step 2: Make the buttery saltine crust

Crush the saltine crackers in a zip-top bag with a rolling pin until fine, sandy crumbs form (some small flakes are okay). In a bowl, stir together the crumbs and 3 tbsp sugar. Pour in the melted butter and mix with a fork until every crumb looks damp and holds together when squeezed.

Step 3: Press and par-bake the crust

Press the crumbs firmly and evenly into the bottom and up the sides of the pie plate using a flat-bottomed measuring cup. Aim for a compact, even shell with no thin spots. Bake for 15 minutes until lightly golden and fragrant. Transfer to a rack and cool 10 minutes. Reduce the oven to 325°F (163°C).

Step 4: Whisk the brown-sugar sour cream filling

In a medium bowl, whisk the brown sugar, flour, and salt. Add the eggs and whisk until smooth and glossy. Switch to a spatula and stir in the sour cream, lemon juice, and vanilla until velvety-smooth with no streaks. If you see small lumps, strain the mixture through a fine-mesh sieve.

Step 5: Fill and bake to a gentle wobble

Pour the filling into the warm crust and smooth the top. Bake at 325°F (163°C) for 28–35 minutes, until the edges are set and the center jiggles like gelatin when the pan is nudged. An instant-read thermometer inserted 1 inch from the center should read 170–175°F (77–79°C). If the crust browns too fast, shield the rim with foil.

Step 6: Cool slowly, then chill to set

Cool the pie on a rack for 1 hour. Refrigerate uncovered until thoroughly chilled and set, at least 4 hours (overnight is ideal). Chilling firms the custard and makes slicing clean and easy.

Step 7: Finish with cinnamon-sugar and slice

Stir together 1 tbsp sugar and 1/2 tsp cinnamon (plus a tiny pinch of flaky salt if you like). Dust evenly over the chilled pie just before serving. Slice with a warm, dry knife, wiping between cuts. Add a spoonful of softly whipped cream if desired.

Pro Tips

• Room-temperature eggs and sour cream blend more smoothly and help prevent curdling.
• For the crispest crust, press the crumbs firmly and bake until lightly golden before adding the filling.
• A gentle wobble is your friend—overbaking leads to a grainy texture. Use an instant-read thermometer for precision.
• Strain the filling if you see any lumps for the silkiest custard.
• Dust with cinnamon-sugar just before serving so it stays distinct and aromatic.

Variations

• Maple-Brown Sugar: Reduce brown sugar to 3/4 cup (165 g) and add 2 tbsp pure maple syrup; increase flour to 4 tbsp (32 g). Same bake time.
• Bourbon Vanilla: Add 1 tbsp bourbon and an extra 1/2 tsp vanilla to the filling for warming depth.
• Gluten-Free: Use gluten-free saltine-style crackers and confirm your flour substitute is a 1:1 gluten-free blend.

Storage & Make-Ahead

Refrigerate the pie, loosely covered, for up to 3 days. Dust with cinnamon-sugar right before serving so it doesn’t dissolve on the surface. The crust can be pressed and par-baked up to 2 days ahead; store covered at room temperature. Freezing the baked custard is not recommended, but the crust alone freezes well (wrap tightly and freeze up to 2 months).
