In a bowl, pour in the sugar-pistachio mix. Sift the flour, cornstarch, baking powder, soda, and salt into it. Whisk them all up till combined.

Grab another bowl, and mix olive oil, soy milk, vinegar, and vanilla together.

Pour the wet ingredients into the dry ones and stir gently. Stop when there are just a few spots of dry flour remaining.

Pour the batter into your prepared pan. Bake it for 35-45 minutes. Push in a skewer to test—if batter sticks, leave it in for another 5 minutes. Cool on a wire rack.

Once it’s cooled completely, use a skewer to poke holes all over the surface.
