Start by crushing the Oreo cookies, keeping a few aside for garnish.
Melt the butter and mix it with the crushed cookies. Distribute and fill the cookie mixture at the bottom of the glasses.
Next, whip the cream and add room temperature cream cheese and powdered sugar. Stir until smooth, forming the next layer.
Prepare the chocolate mousse according to the package instructions; this will be the next layer in the glasses.
Top it all off with some fresh strawberries and half an Oreo cookie for garnish.
