With pre-cooked sausage I'd use 400 degrees and check after 10 min. to see if bacon is crisp.
May need another 5 min.

I've done them at 350° for 20-25 minutes watching to make sure the sugar doesn't burn.

Thanks Ladies-- my oldest grandson asked if I would do these for our family Christmas gathering-- & now Gramma won't disappoint !

Oh & Ginger do I parboil them to get rid of some of the grease before they're wrapped & baked?

I guess you could or just have them on a rack so they're not swimming. LOL

Do you think they would travel well? I want to make them and take to a party, we would be driving about 40 minutes to the party. I don't think the oven will be available there.
I could put them in a preheated crock pot to travel if necessary after they come out of the oven at home.

I know you don't need this anymore, Diane, but I just happened to come across this on another site and so here it is FYI.

Take a package of Little Smokie mini sausages, wrap each in a half strip of bacon, secure with a toothpick and place side by side in a baking pan. Sprinkle with dark brown sugar and bake at 375F for 30 minutes. So Good!! Vilcat
