Making Coconut Oil Brownies involves a lot of gently stirring and scraping, so I use one tool – a heavy duty, heat resistant silicone scraper. I like the one I bought years ago from Pampered Chef. In fact, I liked it so much a bought a second.
I almost always use metal pans, but if you only have an 8 inch glass pan you could try that. It is usually recommended to reduce the baking temperature by 25 degrees when using a glass pan, so reduce temp to 325.
