In a mixing bowl, cream together the butter and sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition.

Stir in the milk and vanilla extract.

In a separate bowl, combine flour and baking powder. Gradually add to the wet mixture.

Pour the batter into the prepared baking pan and bake for 30 minutes or until a toothpick comes out clean.

In a bowl, fold the crushed cookies into the whipped cream.
