Prepare a round or circular tart pan of your choice. I chose round tart pan. Place oreo cookies in the jar of your mixer or processor. Grind them into fine powder. Now add melted butter, and grind them together to make a thick sticky paste.
Scoop this cookie mixture into the prepared pan. Spread it evenly. Using the back of a spoon, press it down to make a uniform base. Allow it to freeze until you prepare the filling.
Roughly chop the chocolate and place in a heat proof bowl, keep aside. Heat cream in a thick pan on low heat, do not allow it to boil. Pour hot cream over chopped chocolate.
Allow it to stand for few minutes. Using a spoon or a whisk, stir it gently till the chocolate melts. The heat of the cream will melt the chocolate.
Pour the ganache over the prepared tart base. Wash and clean fresh strawberries. Press them into the ganache. Allow the tart to set overnight or at least for 2 hours in refrigerator.
When ready to serve, remove from refrigerator and slice it. Enjoy.
