The above batter can be baked in 2 5 inch cake pans. I made only half of the measurement and used a 6 inch pan. So mine was thinner in height.
Preheat the oven to 180C, grease the cake pans with oil and line it with parchment paper.
In a large bowl, sift together wheat flour and ragi flour along with cocoa powder.
In another bowl, mix sugar with oil and beat well. Then add the curds. continue beating.
To this add baking soda and baking powder and whisk well to combine.
Add the melted dark chocolate to this mix and combine well.
To this wet mix, add the dry flour mix in two batches and mix with a spatula.
Fold in gently. Finally, add in the chocolate chips and give a final stir.
Divide the batter between the two cake pans, give it a good tap and bake the cake in the preheated oven for 40-45 minutes or until a skewer inserted in the middle comes out clean.
Once baked, let it stand for 10 mins, then top it with thick dark chocolate ganache.
