Preheat the oven to 330 degrees F.
Grease an 8-inch round springform baking pan. Set aside.
Combine sugar and butter in a large mixing bowl. Using a handheld beater, cream butter, and sugar together until light in color and fluffy.
Next, add mawa to the creamed sugar-butter mixture. Beat the mixture until smooth and creamy.
Now, add yogurt to the mawa mixture. Mix until combined.
Add baking powder. Mix it well. Make sure to scrape the sides of the bowl regularly.
Add fine sooji to this mix. Beat until smooth and well blended.
Slowly add milk to the mawa sooji mixture. The batter may look curdled at this point. Don’t worry; it’s absolutely fine. This curdling of ingredients will not affect the final cake.
Once all the milk is used, scrape the sides of the bowl one last time.
Pour the sooji mawa cake batter in the greased pan.
Use an offset spatula spread the sooji mawa cake batter evenly into the corners and along the edges of the baking pan.
To help get rid of trapped air bubbles, tap the baking pan on the counter a few times. Sprinkle crushed pistachios on top.
Place the pan in the preheated oven and bake for 40-42 minutes or until the toothpick comes out clean.
Remove the Sooji mawa cake from the oven and set it over the counter to cool. Allow the cake to cool in the pan for 10-12 minutes.
Run a knife around the edges of the cake to loosen the band. Serve hot with a cup of hot tea or coffee.
