If you follow the same ratio of soda to powder and use same product it should come out the same. You also need a relitively fresh box of soda each time. The soda part is really important. I have made poo batches many times from using soda that was just in my cupboard.
I bake a cake about once or twice a year and always have to remind myself not to use that box I’ve been using to deodorize the fridge for whatever time it’s been since I baked the last one.
