Instructions
 

Preparation

  • In a large bowl, whisk together the instant vanilla pudding mix and milk until thickened.
  • In another bowl, whip the heavy cream with the powdered sugar until soft peaks form.
  • Fold the whipped cream into the pudding mixture until fully combined.
  • Stir in the lemon juice, lemon zest, and vanilla extract.

Assembly

  • In a 9×13-inch baking dish, layer graham crackers at the bottom.
  • Spread half of the lemon pudding mixture over the crackers.
  • Add another layer of graham crackers on top, followed by the remaining pudding mixture.
  • Top with another layer of graham crackers.

Chilling

  • Refrigerate for at least 4 hours, or overnight if possible.

Notes

Chill long enough for flavors to meld; at least 4 hours or overnight is best. If using graham crackers, assemble the top layer closer to serving time if they become too soft.
