How to Make No Bake Peanut Butter Éclair Cake Step by Step

Step 1: Make the Peanut Butter Filling

In a large bowl, whisk together the instant pudding mix and cold milk until thickened. Add the peanut butter and whisk until smooth and fully combined. Gently fold in the whipped topping until the mixture is light, fluffy, and irresistible.

Step 2: Create the First Layer

Arrange a single layer of graham crackers in the bottom of your baking dish. Break them as needed to fully cover the bottom—this will become your “cake” layer once chilled.

Step 3: Add the Filling

Spread half of the peanut butter pudding mixture evenly over the graham crackers. Take a moment to admire it—it already smells incredible!

Step 4: Repeat the Layers

Add another layer of graham crackers, followed by the remaining peanut butter filling. Finish with one final layer of graham crackers on top.

Step 5: Add the Chocolate Topping

Spread chocolate frosting evenly over the top layer. If the frosting is too thick, warm it slightly so it spreads smoothly without disturbing the layers underneath.

Step 6: Chill Until Perfect

Cover and refrigerate for at least 4 hours, though overnight is highly recommended. This gives the graham crackers time to soften into that classic éclair-cake texture.
