For the brownies, I had to get a square or rectangular pan - how could I make brownies in a round pan without even a single corner piece 🙃 - so I ordered this set of three 6-inch square pans with lids (eG-friendly Amazon.com link). One pan + lid was $9.49, two was $19.99 and three was priced at $16.49 or $5.50 each. The brand is Teamfar. I thought that was reasonable and I'm quite pleased with the quality. Thought I'd pass it on in case anyone else in the US is looking to expand their collection of tiny bakeware!
