Convert from Micro to Conventional?

There is a recipe from a poster that isn't still on CC for Microwave PB Banana Brownies.

It says to micro on high for 6-8 minutes. Anyone have any idea what temp to bake it at in a conventional oven and approx how long?

I don't like microwaves but the recipe looks yummy!

It will be around 350 degrees for 35 to 40 minutes,

BUT I betcha they taste and turn out better in the microwave. From experience, microwave recipes are just that because they've been made specifically for the microwave. (Thus, tasting better)

Ok-will try it and see. Thanks!
