Can i use non stick cooker (futura pressure cooker) for making cake without oven
You can "steam" a cake in the pressure cooker using the Bain Marie or Pan-in-pot method.  Basically put the cake batter in a smaller heat-proof container (usually 7" or 20cm) that is buttered as usual.  Then in the pressure cooker add enough water to equal the minimum liquid (usually 1-2 cups), and a steamer basket or rack.  Add the container containing the batter onto the rack and pressure cook for about 20 minutes with natural release.  You'll want to increase the baking soda or powder by 50% to compensate for the extra pressure - but generally most of the "rise" in the cake will happen while the cooker is reaching pressure.

P.S. Be sure to construct a sling out of foil (a strip folded three times and placed under the container with the ends coming up the side of the cooker) to more easily lower and raise the cake.
