Creating your No Bake Eclair Cake is straightforward when you follow these simple steps:

1. Prepare the Pudding Layer: In a mixing bowl, whisk together the whole milk and instant vanilla pudding. Let it sit for about five minutes to thicken.

2. Make Cream Cheese Mixture: In another bowl, beat the softened cream cheese with the powdered sugar until smooth. Then, fold in the whipped topping for a lighter texture.

3. Combine Mixtures: Gently incorporate the thickened pudding mixture into the cream cheese blend until well combined.

4. Layer the Graham Crackers: In a 9×13 inch dish, arrange a single layer of graham crackers at the bottom.

5. Add Pudding Mixture: Spread half of the creamy pudding mixture evenly over the graham crackers.

6. Repeat Layering: Place another layer of graham crackers on top of the pudding mixture. Add the remaining half of the pudding mixture and spread it evenly.

7. Finalize with Graham Crackers: Top with one more layer of graham crackers, covering the pudding completely.

8. Prepare the Chocolate Topping: In a small saucepan, melt the chocolate chips with the vegetable oil and water over low heat. Stir continuously until the mixture is smooth.

9. Pour Chocolate Layer: Once melted, pour the chocolate mixture over the final layer of graham crackers, spreading it evenly.

10. Chill and Serve: Cover the dish with plastic wrap and refrigerate for at least one hour to allow the layers to set before serving.

These straightforward steps make assembling your delicious No Bake Eclair Cake a breeze!
