Leda, definitely a Peperomia. Looks like my P. clusiifolia. It might get redder/pinker edges if more light is possible for it this summer. Looks robust though, nice!! Mine bloomed right after I brought it inside for winter. More sun might help your plant with that, though the blooms aren't exciting to anyone except a real plant geek, as folks yakking here tend to be. You've probably seen pics and already know that... But most plant people like the fact that their plant is healthy/happy enough to bloom, even if the bloom just looks like a soft stick. Giving it a prune may have caused it to not be ready yet, but you DO have a ton of pretty leaves. Looks like doing that was a good idea..
