Vanilla custard filling wrapped in a crispy cinnamon-sugar tostada with a caramelized sugary shell — this is Taco Bell's wildest dessert move yet and you can make it at home.
Make the vanilla custard: In a saucepan, whisk together milk, cream, ½ cup sugar, cornstarch, and salt. Cook over medium heat, stirring constantly, just until steaming — don’t boil. In a bowl, whisk egg yolks. Temper with a little of the hot milk, then whisk egg mixture back into saucepan. Cook, stirring, until thick enough to coat a spatula (about 5 minutes). Stir in vanilla and butter. Chill in fridge at least 1 hour.
Prep the cinnamon-sugar tostada shells: Mix ½ cup sugar with ground cinnamon in a shallow dish. Lightly butter both sides of each tostada shell, then press into the cinnamon-sugar mix so the surface is well coated. Bake shells at 350°F for 5 minutes to set the coating (or air-fry for max crunch).
Assemble the Crunchwraps: Lay one flour tortilla flat. Spoon 3–4 tbsp chilled custard in the center. Top with a cinnamon-sugar tostada shell for crunch (just like Taco Bell’s textural layering). Fold tortilla edges up over the tostada to fully enclose it, pleating securely. Repeat for all servings.
Caramelize the shell: Brush the outside of each wrap with water. Sprinkle the top with a generous, even layer of remaining granulated sugar (about 1 tbsp per slider). Using a kitchen torch, melt the sugar until it bubbles and turns glassy golden-brown. (Copycat tip: The hard caramel shell cracks like true crème brûlée—don’t skip this for full Taco Bell impact.)
Serve warm: Let the caramel set for 2 minutes, then slice in half. For best contrast, serve while the inside is cool and the outside is crisp, mimicking Taco Bell’s signature hot/cold, crunch/creamy contrast. Dust with extra cinnamon-sugar if desired.
