This Eclair Cake is a delicious no-bake dessert cake consisting of a Graham crackers base, followed by layers of creamy instant pudding mix that is separated with additional crackers (much like a lasagna) and then topped with a decadent chocolate ganache! It’s then left to chill in the refrigerator, allowing all the rich and creamy flavors to combine until it’s time to serve. This dessert is super quick and easy to make, ideal for a cool treat on a warm summer’s day or for whenever you prefer a no-bake sweet treat.
