Ingredients

Directions

  1. In a large bowl, mix pudding mix, milk, and cardamom.
  2. Stir in bananas.
  3. Fold in Cool Whip.
  4. In a 9×13 glass dish, start layering.
  5. Place one layer of graham crackers.
  6. Spread half the pudding mixture on top.
  7. Sprinkle on half of the blackberries.
  8. Add another layer of graham crackers, spreading blackberry jam on top of each cracker first.
  9. Add the rest of the pudding mixture.
  10. Sprinkle on the remaining blackberries.
  11. Top with one more layer of graham crackers, again spreading blackberry jam on each cracker first.
  12. Cover and refrigerate overnight so the graham crackers have a chance to soften.

Notes

  • Chill overnight: The rest in the fridge is essential—it softens the graham crackers into tender, cake-like layers.
  • Bananas fresh: Slice them just before assembling so they stay bright.
  • Cardamom to taste: Its warm spice is subtle here; adjust up or down as you like.
  • Jam between layers: Spreading blackberry jam on the crackers adds moisture and extra berry flavor.
  • Best fresh: Enjoy within a day or two before the bananas begin to darken.

Why This Works

  • Softening in reverse: Overnight moisture from the pudding turns crisp grahams tender, giving you cake-like layers with no baking.
  • Pudding sets firm: The mix thickens with milk into a spoonable, sliceable structure.
  • Folding in Cool Whip: Gently folding whipped topping lightens the pudding for an airy texture.
  • Jam seals the crackers: A thin layer of jam adds flavor and helps hold each cracker layer together.
