Combine all ingredients and mix well. Mixture should look like wet sand. Press mixture onto the bottom and sides of a removable bottom tart pan or cheesecake pan. Bake for 8 to 10 minutes until crust is dry and darker in color. Cool completely before filling. Do not remove from pan.
For the Filling
Whip together the cream cheese and yogurt until creamy and smooth. Add remaining ingredients, except for blueberries. Carefully pour into prepared crust, spreading evenly. Take care not to break the crust. Arrange blueberries on top of filling. Refrigerate at least one hour, overnight if possible, for tart to become firm. Carefully remove from pan, cut, serve, and enjoy!
