Full Ingredients

For the Grape-Nuts Pudding

• 3 cups (710 ml) whole milk
• 3/4 cup Grape-Nuts cereal (about 100 g)
• 4 large eggs
• 1/2 cup (100 g) granulated sugar
• 1 tbsp (14 g) unsalted butter, melted and slightly cooled, plus a little for greasing the dish
• 2 tsp pure vanilla extract
• 1/4 tsp freshly grated nutmeg, plus more to dust the top
• 1/4 tsp fine sea salt
• Hot water for the water bath

For Serving

• Lightly sweetened whipped cream (1 cup heavy cream + 2 tbsp powdered sugar + 1/2 tsp vanilla, whipped to soft peaks)

Step-by-Step Instructions

Step 1: Heat the oven and prepare the baking dish

Preheat the oven to 325°F (163°C). Grease a 2-quart (2 L) baking dish with butter. Place the dish inside a deep roasting pan to prepare for a water bath. Put a kettle of water on to boil.

Step 2: Warm the milk and soak the cereal

In a medium saucepan, warm the milk over medium heat until steaming and small bubbles appear around the edges (about 175–180°F / 79–82°C). Do not boil. Remove from heat, stir in the Grape-Nuts, and let soak for 10 minutes so the cereal softens and begins to flavor the milk.

Step 3: Make the custard base

In a large mixing bowl, whisk the eggs, sugar, salt, vanilla, and nutmeg until well combined and slightly lightened, 30–45 seconds. This dissolves the sugar and gives you a smooth custard.

Step 4: Temper the eggs and finish the mixture

While whisking constantly, slowly stream the warm milk-and-cereal mixture into the eggs to temper them and prevent curdling. Whisk in the melted butter. If there’s excess foam, skim it off for a smoother surface.

Step 5: Assemble the water bath and bake

Pour the custard into the prepared baking dish. Dust the top lightly with more nutmeg. Slide the roasting pan into the oven, then carefully pour the hot water into the roasting pan until it reaches about halfway up the sides of the baking dish.

Bake for 40–50 minutes, until the edges are set and the center has a slight, even jiggle when nudged. An instant-read thermometer inserted in the center (not touching the bottom) should read 170–175°F (77–80°C). Avoid overbaking; the custard will finish setting as it cools.

Step 6: Cool, then chill

Remove the baking dish from the water bath and place on a cooling rack. Cool to room temperature, about 1 hour. Cover and refrigerate until thoroughly chilled and set, at least 2 hours and up to 24 hours. During baking and cooling, the Grape-Nuts will settle into a toasty, pudding-like layer on the bottom—exactly what you want.

Step 7: Serve

Spoon the chilled pudding into bowls, making sure each serving includes some of the toasty bottom layer. Add a generous dollop of softly whipped cream and a whisper of freshly grated nutmeg. Serve cold.

Pro Tips

• Water bath wisdom: The gentle, even heat of a bain-marie prevents scrambled eggs and keeps the custard ultra-silky.
• Don’t boil the milk: Overheating can curdle the custard later. Warm to steaming, not simmering.
• Pull it jiggly: Remove from the oven when the center still wobbles slightly—carryover heat will finish the set.
• Use fresh nutmeg: Grating whole nutmeg right before baking gives a warm, nostalgic aroma and cleaner flavor.
• Chill thoroughly: The cereal layer firms up as it cools, giving that classic creamy top/toasty bottom contrast.

Variations

• Maple-Vanilla: Replace 1/4 cup of the sugar with 1/4 cup pure maple syrup and reduce the milk by 2 tbsp (30 ml) to keep the custard balanced.
• Spiced Raisin: Stir in 1/2 cup (70 g) raisins (briefly soaked in hot water, then drained) and add 1/2 tsp ground cinnamon with the nutmeg.
• Coconut Twist: Swap 1 cup (240 ml) of the milk for full-fat unsweetened coconut milk. Garnish with toasted coconut flakes before serving.

Storage & Make-Ahead

Refrigerate covered for up to 4 days. Serve cold or just slightly cool. Freezing is not recommended, as the custard can weep and the cereal layer loses its pleasant texture. The pudding is an excellent make-ahead dessert—bake it the day before and chill overnight.
