I just googled and found this one ..let us know how it goes :-)

Yeastless Pizza Crust

1 3/4 cup all-purpose flour

1 tbls granulated sugar

1/2 tsp baking soda

1/2 tsp salt

2/3 cup buttermilk
For a thin, crisp crust, try this simple soda recipe. And remember: there's no reason why you can't add some herbs to enhance the flavor!

Combine flour, sugar, baking soda, and salt in a medium-sized bowl. Make a well in the center and add buttermilk; stir just enough to combine. Form dough into a ball, flatten slightly, then roll out with a rolling pin to the shape and size of your pan or pizza stone or pat into shape with your hands.
