Preheat oven to 350°F (175°C).

Combine butter, flour, brown sugar, salt, and 1/2 cup nuts in a bowl.

Mix ingredients until crumbly.

Press the mixture evenly into a 9x13 inch baking pan.

Bake for 12 minutes, or until lightly golden.

Let the crust cool completely.

In a separate bowl, cream together cream cheese and sugar until smooth.

Stir in the remaining 1/2 cup nuts.

Spread the cream cheese mixture evenly over the cooled crust.

Slice the bananas and arrange them over the cream cheese layer.

In a medium saucepan, whisk the strawberry-flavor danish dessert mix into the cold water.

Bring the mixture to a full boil over medium heat, stirring constantly.

Boil for exactly 1 minute, continuing to stir.

Remove from heat and let the pudding cool slightly.

Pour the warm pudding evenly over the bananas.

Refrigerate the dessert for at least 1 hour, or until completely cool and set.

Before serving, spread the thawed Cool Whip evenly over the top of the pudding.

Slice and serve chilled.
