No-bake chocolate eclair cake is a classic icebox cake that features layers of graham crackers, pudding, and chocolate. It takes just a few minutes to put together, but the magic happens as it takes a nice long chill in the refrigerator. If you've never had one, you absolutely must give it a try.
In a large mixing bowl, whisk together the 3 cups milk and 7 ounces vanilla instant pudding mix.
Stir in 8 ounces whipped topping.
Arrange a layer of graham crackers on the bottom of a 9x13-inch baking dish, covering the bottom of the pan as completely as possible without overlapping.
Spread half of the pudding mixture over the graham crackers.
Top the pudding with another layer of graham crackers, followed by the remaining pudding mixture. Top the pudding with a final layer of graham crackers.
Cover and refrigerate for at least 30 minutes.
In a small bowl, melt together 1½ cups chocolate chips and 14 ounces sweetened condensed milk using 20 second bursts in the microwave.
Once you can stir the mixture smooth, spread over the chilled icebox cake. Make sure you get it all the way to the edges.
Cover and chill for at least 3 more hours before serving.
Notes
If you don't want to make the chocolate chip and condensed milk fudge topping, you can use a can of chocolate frosting.
Feel free to experiment with different flavors of pudding mix. Chocolate pudding would be fabulous, so would white chocolate pudding.
