Decadent Layered Cookie Lasagna Ingredients
For the Cookie Layers
• Chocolate Chip Cookies – Structure the dessert; you can swap in oatmeal, peanut butter, or shortbread cookies for a delightful twist.
For the Vanilla Custard
• Milk – Hydrates and forms the custard base; whole milk yields a creamier texture, but any milk type will work.
• Heavy Cream – Adds richness to both the custard and ganache; use half-and-half for a lighter option if desired.
• Granulated Sugar – Sweetens the custard; brown sugar can substitute for a deeper, more complex flavor.
• Egg Yolks – Provide richness and help thicken the custard; using whole eggs may alter the texture.
• Cornstarch – Acts as a thickening agent for the custard; you can replace it with flour if necessary, but the outcome may vary.
• Vanilla Extract – Enhances flavor; consider using a vanilla bean for a more intense essence.
• Salt – Balances the sweetness and enhances flavors.
For the Chocolate Ganache
• Semi-Sweet Chocolate Chips – The main ingredient for the ganache; feel free to use dark or milk chocolate chips for different sweetness levels.
• Unsalted Butter – Adds creaminess to the ganache; margarine can be used in a pinch, though the taste will slightly differ.
• Powdered Sugar – Sweetens and thickens the ganache; adjust the amount for your preferred sweetness.
For Garnish
• Additional Chocolate Chips or Cookie Crumbles – Use these for optional decoration to elevate the presentation.
This Decadent Layered Cookie Lasagna with Creamy Vanilla Custard and Rich Chocolate Ganache is not just a treat; it’s an experience waiting to happen!
Step‑by‑Step Instructions for Decadent Layered Cookie Lasagna with Creamy Vanilla Custard and Rich Chocolate Ganache
Step 1: Prepare Vanilla Custard
In a medium saucepan over medium heat, combine 2 cups of milk, 1 cup of heavy cream, ¾ cup of granulated sugar, and a pinch of salt. Stir occasionally until the mixture is hot but not boiling, about 5 minutes. This will form the creamy base for your vanilla custard, preparing you for the next step.
Step 2: Temper Eggs
In a separate bowl, whisk together 4 egg yolks and ¼ cup of cornstarch until smooth. Gradually add the hot milk mixture to the yolks, whisking constantly to prevent cooking the eggs. This step ensures your custard is rich and smooth without any lumps.
Step 3: Cook Custard
Pour the egg and milk mixture back into the saucepan over medium heat. Stir continuously for about 5-7 minutes, until the custard thickens and coats the back of a wooden spoon. Once thickened, remove from heat and stir in 2 teaspoons of vanilla extract. Transfer to a bowl, cover with plastic wrap, and chill in the fridge for 1-2 hours.
Step 4: Make Ganache
In a small saucepan, heat 1 cup of heavy cream until just steaming, then pour it over 1 ½ cups of semi-sweet chocolate chips and 2 tablespoons of unsalted butter in a mixing bowl. Allow it to sit for a couple of minutes before whisking until smooth. The ganache will become glossy and will eventually top your layered cookie lasagna.
Step 5: Assemble Cookie Lasagna
In a rectangular dish, lay down a single layer of chocolate chip cookies. Spoon half of the chilled vanilla custard over the cookies, spreading it evenly. Repeat with another layer of cookies followed by the remaining custard, finishing with a final layer of cookies. The multiple layers create the decadent structure of your cookie lasagna.
Step 6: Chill Again
Cover the assembled dessert with plastic wrap and refrigerate for at least 4 hours, or even better, overnight. This chilling time allows the layers to meld together, enhancing the flavors of your Decadent Layered Cookie Lasagna with Creamy Vanilla Custard and Rich Chocolate Ganache.
Step 7: Serve
Once ready to serve, pour the cooled ganache over the top layer of cookies, letting it cascade down the sides if desired. Optionally, sprinkle with chocolate chips or cookie crumbles for an extra touch. Cut into squares and enjoy this delightful no-bake dessert that is sure to impress!

Storage Tips for Decadent Layered Cookie Lasagna
Fridge: Keep your Decadent Layered Cookie Lasagna in an airtight container for up to 3 days. This ensures it remains fresh and the flavors meld beautifully.
Freezer: If you want to prepare ahead, freeze individual slices wrapped tightly in plastic wrap for up to 1 month. Thaw overnight in the fridge before serving.
Serve Fresh: Although it can last a few days, this dessert is best enjoyed when freshly chilled. The texture and flavors shine the most right after chilling.
Reheating: This dessert is best served cold, so no reheating is needed. Just slice and enjoy its luscious layers straight from the fridge!

Make Ahead Options
These Decadent Layered Cookie Lasagna with Creamy Vanilla Custard and Rich Chocolate Ganache are perfect for busy home cooks looking to streamline their dessert preparations! You can prepare the vanilla custard and chocolate ganache up to 2 days in advance. Simply cook the custard and let it cool in the refrigerator, covered tightly with plastic wrap to prevent a skin from forming. The ganache can also be made ahead; just allow it to cool at room temperature before storing it in an airtight container. When you’re ready to serve, assemble the cookie layers with the prepared custard, chill your dessert for at least 4 hours (ideally overnight), and then pour on the ganache just before serving for a dessert that feels freshly made!
Expert Tips for Decadent Layered Cookie Lasagna
Tempering Eggs: Make sure to whisk the egg yolks gradually with the hot milk to prevent scrambling. This creates a silky custard.
Consistency Check: Keep an eye on your ganache! Let it cool slightly before spreading for the best thickness.
Custard Thickness: If your custard is too runny after chilling, heat it gently while stirring to thicken up. A thick custard layers beautifully!
Alternative Cookies: Feel free to personalize your dessert. Substitute chocolate chip cookies with oatmeal or peanut butter cookies for a different flavor profile.
Fruit Layers: Adding fresh fruit? Use moderation! Thin layers of berries or bananas can enhance flavor but avoid over-saturation between the cookie layers.
Garnishing Tips: Elevate your presentation! A sprinkle of chocolate chips or cookie crumbles on top makes for a stunning finish to your Decadent Layered Cookie Lasagna.

Decadent Layered Cookie Lasagna with Creamy Vanilla Custard Recipe FAQs
How do I choose the right chocolate chip cookies?
Absolutely! For the best flavor and structure, I recommend using freshly baked chocolate chip cookies. If you’re feeling adventurous, try swapping in oatmeal, peanut butter, or shortbread cookies for a delightful twist. The key is to ensure the cookies are not overly soft, as they need to hold up between the layers of custard and ganache.
What is the best way to store the cookie lasagna?
Store your Decadent Layered Cookie Lasagna in an airtight container in the fridge for up to 3 days. The flavors continue to meld over time, making each bite even more delicious. Just make sure it’s well covered to avoid any odors from other foods in the fridge!
Can I freeze the cookie lasagna?
Yes! For freezing, slice the cookie lasagna into individual portions and wrap each piece tightly in plastic wrap. Then, place them in a freezer-safe container or bag. It can last up to 1 month in the freezer. When you’re ready to enjoy, thaw overnight in the refrigerator before serving. This makes it perfect for ahead-of-time prep!
What if my custard doesn’t thicken properly?
If your custard turns out too runny, don’t worry! Simply return the mixture to the heat in a saucepan and stir continuously for 2-3 minutes until it thickens. Make sure the heat is low enough to avoid scrambling the eggs. You could also add a bit more cornstarch dissolved in milk to help it along!
Is this recipe suitable for dietary restrictions?
Very! You can easily make this dessert gluten-free by using gluten-free cookies in place of traditional chocolate chip cookies. If you’re concerned about allergies, be sure to check each ingredient and opt for allergy-friendly substitutions, like using dairy-free milk and cream for the custard and ganache. This way, everyone can enjoy this indulgent treat!
How long should I let the dessert chill before serving?
For the best results, chill your assembled Decadent Layered Cookie Lasagna for at least 4 hours or, ideally, overnight. This allows the flavors to meld beautifully and the layers to set perfectly, making for a slice that holds its shape when served. Enjoy this chilled delight with friends and family!
