To begin making the Eggless Chocolate Ragi Cake - Pressure Cooker Cake first we will preheat our pressure cooker with salt or fine sand. 

Into the pressure cooker, add 1 cup of salt and make a bed of sand at the bottom of the pressure cooker. 

Cover the pressure cooker without the weight on and allow it to get preheated over medium heat for a minimum of 10 minutes.

In the meanwhile, prepare the flax meal egg replacer.

In a small mixing bowl, add the flaxseed powder and 3 tablespoons of water. Stir well to combine and allow it to rest for 10 minutes. After 10 minutes you will notice that the flax meal mixture will get a gooey consistency similar to that of eggs.

Once this is done, in a large mixing bowl; add the maida, ragi flour, cocoa powder, baking powder, sugar, cinnamon powder and give it a stir.

Add the milk, nutralite classic spread, flax meal egg replacer mixture and stir well to combine. Beat until the Eggless Chocolate Ragi Cake batter is fluffy. 

Grease the baking tin with oil and dust it with flour. Ensure the baking pan will fit into the pressure cooker.  Typically you can use a rice bowl which fits into the pressure cooker as your cake pan.

Pour the Eggless Chocolate Ragi Cake batter into the greased and dusted pan and place it into the preheated sand oven.

Cover the pressure cooker without the weight on and bake on low to medium heat for about 35 to 40 minutes until a toothpick when inserted inside comes out clean.

Once done, turn off the pressure cooker oven & remove the pan from the heat and allow it to cool completely. 

Once cooked, gently slide the knife around the edges to release the cake and cut it into wedges and serve.

Serve the Eggless Chocolate Ragi Cake along with a hot cup of Adrak Chai or even Filter Coffee for a snack or for a Sunday Morning Brunch along with Cheese Masala Omelette, Baked Beans & Toast.
