Method
Make the banana pudding cream
- Whisk the instant banana pudding mix with the whole milk for 2 minutes until it thickens, then stop and scrape the bowl. The mixture should look visibly thicker, like spoonable pudding.
- Fold in the whipped topping until no streaks remain. Mix just until smooth and uniform.
Assemble the layered eclair cake
- Line a 9x13 pan with a single layer of graham crackers. Arrange them tightly so the bottom is fully covered.
- Spread 1/3 of the pudding over the graham crackers. Spread to the edges for even layers.
- Add sliced ripe bananas over the pudding layer. Cover the pudding in a single, even layer.
- Add another graham cracker layer directly over the bananas and pudding. Place crackers in a tight, even row.
- Spread another portion of pudding over the second cracker layer and add sliced bananas again. Keep the fruit distribution consistent for clean slices.
- Add a final graham cracker layer and spread the remaining pudding over the top crackers. Cover the surface fully so the top is creamy.
Make and add the chocolate glaze
- Whisk the unsalted butter, unsweetened cocoa powder, powdered sugar, milk, and vanilla extract until smooth. The glaze should be thick but pourable and glossy.
- Pour the chocolate glaze over the top and spread lightly only if needed. Let it flow to the edges for a full coverage layer.
Chill to soften the crackers
- Refrigerate the banana split eclair cake for 8 hours or overnight until the graham crackers are completely soft. The filling should be set when sliced, with neat layers visible.
Notes
Pro tip: For the most cake-like texture, use fully ripe bananas and press the cracker layers down gently as you assemble so pudding makes full contact. Store covered in the refrigerator for up to 4 days; freezing is not recommended because the crackers can lose texture after thawing. For a lighter option, swap the whole milk for low-fat milk and use light whipped topping if desired (texture may be slightly softer).
