A decadent no-bake dessert layering creamy vanilla pudding, ripe bananas, crunchy Biscoff cookies, and homemade caramel sauce for the ultimate comfort dessert.
Slice bananas and toss with lemon juice. Crush half the Biscoff cookies into chunky pieces, leave rest whole.
Whisk egg yolks and sugar until pale. Combine cornstarch with 1/2 cup milk. Heat remaining milk until steaming, then slowly whisk into egg mixture. Return to pan and cook over medium heat, whisking constantly, until thickened (5-7 minutes). Stir in vanilla and salt.
Heat 1 cup sugar in heavy saucepan over medium heat until melted and amber. Add butter (will bubble), then slowly pour in cream while whisking. Cook until smooth, stir in vanilla and salt.
Layer crushed cookies in serving dish, followed by pudding, banana slices, and caramel drizzle. Repeat layers, ending with whole cookies and final caramel drizzle.
Refrigerate for at least 4 hours before serving to allow flavors to meld and layers to set properly.
