Cookie Custard Cake is a no-bake, layered dessert that turns basic pantry ingredients into something truly irresistible. With layers of tender cookies and rich homemade custard, it’s creamy, nostalgic, and perfect for both special occasions and everyday indulgence. It’s also a great make-ahead option for busy families or anyone craving an easy yet satisfying sweet.

This dessert is inspired by traditional refrigerator cakes and tiramisu-style layer desserts. A vanilla custard is cooked on the stovetop with cornstarch to thicken it, then layered with cookies like digestives or tea biscuits and chilled until firm. It’s a beloved treat across many cultures, evoking the flavors of childhood comfort food with the elegance of creamy, no-bake simplicity.
