Preheat the oven to 300 F and adjust the oven rack to center.
To blend the Oreo biscuits, crush them (about 20-25 of them) and grind them in a mixer to a fine powder.
Take the powdered biscuits in a medium-sized bowl. Add powdered sugar and mix it well. You can skip adding sugar if you don’t want extra sweetness apart from the biscuits.
Also add baking powder and baking soda to the mixture and blend it well.
Start adding raw milk to the mixture in little quantities so that you can get a thick and flowing liquid consistency. The cake batter is ready now.
Grease the cake tin/plate with ghee and place the butter paper over it. You can grease the butter paper as well with a little ghee.
Pro-tip – Just dust maida (all-purpose flour) at the bottom of the cake tin before pouring the batter. If you don’t have a butter paper. Dust well so that the cake comes out easily.
Pour the prepared cake batter into the tin evenly. Tap the tin to release any air bubbles within the batter.
Place the tin in the oven and bake the cake for about 25-30 minutes. An alternate if you don’t have an oven at your disposal, is a kadhai or a cooker. The steps are as follows:
Take about 200gms of salt in a kadhai/cooker and place a small rack or a stand over it.
Heat the contents covered in a medium flame for about 10-15 minutes.
Remove the lid and place the cake tin with the batter on the stand.
Close it with the lid and heat it for about 25-30 minutes.
We are basically creating the same heat as in the oven using a kadhai/cooker to bake the cake.
Remove the baked cake and insert a toothpick to check if it comes out clean. If it does, your oreo cake is ready. If not, you can re-heat it for another 5 to 10 minutes and remove the cake.
Cool it down completely, tilt the tin upside down onto another plate and remove the cake. Remove the butter paper from the top of the cake.
