Preheat your oven to 450°F (232°C). Place a pizza stone in the oven to heat up.

In a large mixing bowl, combine the sourdough discard, all-purpose flour, salt, baking powder, and olive oil. Stir until it forms a dough.

Turn the dough out onto a floured surface and knead gently for about 1-2 minutes until smooth.

Divide the dough into two portions or keep it whole for one large pizza. Roll each portion out to your desired thickness.

Transfer the rolled-out dough onto parchment paper. Brush a thin layer of olive oil over the crust.

Bake the pizza in the preheated oven for 12-15 minutes until edges are golden brown.

Remove from the oven and let cool for 1 minute. Slice and serve warm.
