Banana Cream Dessert Cups

Vanilla custard, fresh banana, and crisp graham crumbs make a simple layered dessert. Cooking the custard from scratch gives it a clean flavor, while assembling shortly before serving keeps the fruit fresh and crumbs distinct.

Details

• Yield: 6 cups
• Prep: 20 minutes
• Cook: 8 minutes
• Chill: 2 hours

Ingredients

• 2 cups whole milk
• 1/3 cup sugar
• 3 tablespoons cornstarch
• 2 large egg yolks
• 1 tablespoon butter
• 1 teaspoon vanilla
• Pinch salt
• 2 ripe but firm bananas
• 1 teaspoon lemon juice
• 3/4 cup graham-cracker crumbs
• 1/2 cup whipped cream, optional

Equipment

Use a medium saucepan, heatproof bowl, whisk, silicone spatula, fine sieve, plastic wrap, knife, and six glasses.

Method

1. Whisk sugar, cornstarch, yolks, salt, and 1/2 cup milk until smooth. Heat remaining milk in the saucepan until steaming.
2. Slowly whisk hot milk into the yolk mixture. Return everything to the pan.
3. Cook over medium-low heat, whisking constantly, until thick bubbles break the surface. Continue 60 seconds to cook the starch.
4. Remove from heat and stir in butter and vanilla. Strain into a clean bowl. Press wrap directly onto the surface and chill two hours.
5. Slice bananas and toss lightly with lemon juice. Layer crumbs, custard, and banana in six cups. Finish with whipped cream if desired.

Cues and troubleshooting

Finished custard coats the whisk and briefly holds a trail. If it is thin, it likely did not reach a full bubble; return it to gentle heat. If small lumps form, straining usually restores smoothness. High heat can scramble the yolks or scorch milk, so stir continuously and reach into pan corners. Firm yellow bananas hold their shape better than heavily spotted fruit.

Substitutions and serving

Vanilla wafers or toasted oat crumbs may replace graham crumbs. Lactose-free dairy milk works well; plant milks vary in protein and may set more softly. Add toasted coconut or chopped pecans only at serving for crunch. Assemble no more than four hours ahead because bananas darken and crumbs absorb moisture.

Storage and safety

Make-ahead strategy

Prepare and chill the custard up to two days ahead. Store crumbs airtight at room temperature and keep bananas whole until assembly. If transporting, use lidded jars in a chilled carrier and pack the crumbs separately. Stir cold custard briefly before layering; vigorous whisking can make it loose. Slice bananas with a clean sharp knife to avoid bruised edges.

Refrigerate custard promptly at 40°F/4°C or colder and use within three days. For egg safety, cook the custard to at least 160°F/71°C. Discard assembled cups left at room temperature longer than two hours, or one hour in hot conditions. Do not freeze; custard can release water and bananas become mushy after thawing.

Use just-ripe yellow bananas; very soft fruit collapses into the layers and releases extra moisture.
