Banana Pudding Parfaits

Ingredients

• 2/3 cup(s) sugar
• 1/4 cup(s) cornstarch
• 1/4 teaspoon(s) salt
• 2 1/2 cup(s) milk
• 4 large egg yolks
• 2 tablespoon(s) unsalted butter, cut into pieces
• 1 teaspoon(s) pure vanilla extract
• 2 bananas, plus more for garnish
• 12 (4 to 5 ounces total) shortbread or other vanilla-flavored cookies, crumbled, plus more for garnish
• Sweetened whipped cream (see Tips), for garnish

Directions

1. Have ready a fine-mesh sieve over a medium bowl. In a medium saucepan, off heat, whisk together sugar, cornstarch, and salt. Very gradually (a few tablespoons at a time), whisk in milk, taking care to dissolve cornstarch; whisk in egg yolks.
2. Whisking constantly, cook mixture over medium heat until the first large bubble forms and sputters. Reduce heat to low; whisking constantly, cook 1 minute. Remove from heat, and immediately pour through sieve into bowl. Stir butter and vanilla into hot pudding. Let pudding cool slightly; meanwhile, slice bananas.
3. In six 8-ounce glasses, alternately layer warm pudding with cookies and bananas, ending with pudding and covering bananas as completely as you can to prevent discoloration. Refrigerate until set, at least 1 hour, and covered with plastic wrap, up to 2 days.
4. To serve, top with whipped cream and more crumbled cookies and sliced bananas.
