They take about three minutes to heat up some frozen. Or as I do, you can put them into a glassmicrowave dish the night before for reheating at work and they will be thawed and cook faster.
I made them in the rice cooker, as I normally do. I added dried cranberries and a stream of honey used 19 ounces of water and one cup of Steel cut oats.
This recipe filled 8 cupcake tin cups. I figure that's about for breakfasts. I put the 10 into the freezer and left it set up about three hours. Then I pop them out of the 10 and put them into a plastic baggie. Now when I am packing my breakfast I can grab one or two and throw it into a dish.
I like to have a hot meal for breakfast at work occasionally. Especially in the winter time.
I'll post some of my other brown bag fast food later this week.
