This 5-ingredient baked graham cracker dessert is the kind of homespun treat that feels right at home on Grandparents Day: simple pantry ingredients, very little prep, and a soft, pudding-like center with a gently crisp top that invites everyone back for another spoonful. It has the spirit of old-fashioned icebox cakes and custard bakes, where humble crackers transform in the oven into something far richer and more comforting than you’d expect.

Serve this warm on its own or with a scoop of vanilla ice cream, a dollop of whipped cream, or a spoonful of stewed berries if you want a little brightness alongside the sweet, buttery layers. Coffee, hot tea, or a glass of cold milk are all natural pairings, and for a larger family meal it fits in nicely after roast chicken, ham, or a simple Sunday supper.

Ingredients

9 whole graham cracker sheets

1 can sweetened condensed milk, 14 ounces
2 cups whole milk
3 large eggs
4 tablespoons unsalted butter, melted

Directions

1. Preheat the oven to 350°F and lightly butter an 8-inch square or similar small metal baking dish.

2. Arrange 3 whole graham cracker sheets in the bottom of the dish, breaking them as needed so they fit in a mostly even layer.

3. In a medium bowl, whisk together the sweetened condensed milk, whole milk, eggs, and melted butter until completely smooth.

4. Pour about one-third of the milk mixture over the graham crackers. Add another layer of 3 graham cracker sheets, pour over another third of the mixture, then finish with the remaining graham crackers and the rest of the liquid.

5. Let the dish stand for 10 minutes so the crackers begin to soften and absorb the custard.

6. Bake for 35 to 40 minutes, until the top is golden in spots and the center is set but still softly yielding.

7. Cool for at least 15 minutes before spooning or slicing into squares and serving warm.

Variations & Tips

Cinnamon version: Add 1 teaspoon ground cinnamon to the custard for a warmer, snickerdoodle-like flavor that works especially well for a holiday family gathering.

Vanilla touch: If you don’t mind going beyond five ingredients, 1 teaspoon vanilla extract gives the dessert a rounder bakery-style aroma and pairs beautifully with the graham crackers.

Texture tip: For the best finished texture, be sure every cracker layer gets moistened with the milk mixture. Dry corners will stay crisper, while fully soaked areas bake up tender and almost cake-like.

Make-ahead note: You can assemble the dish up to several hours ahead and refrigerate it before baking. This softens the graham crackers even more and creates a smoother, more unified custard layer.

Serving idea: This dessert is at its best slightly warm or at room temperature. If chilled, it becomes firmer and more sliceable, almost like an old-fashioned pudding bar.
